What should I tell friends, family or coworkers who are hesitant to get vaccinated?
“It is a normal human reaction to be afraid,” pediatrician Dr. Edith Bracho-Sanchez said. “They’re having a normal reaction, and perhaps they haven’t been able to sit down with their physician.”
She suggests finding a time to have a calm, rational conversation — when neither person is angry or likely to start a fight.
“The first thing I would say is ‘I get it. I totally get where you’re coming from and I understand that you’re concerned about this,’” Bracho-Sanchez said.
It’s also important to cite scientific data — like the truth about side effects, the safety of Covid-19 vaccines and why it’s important for young, healthy people to get vaccinated.

Will we need Covid-19 booster shots? If so, how will we know when we need them?
It’s not clear if or when vaccine booster shots might be needed, CDC Director Dr. Rochelle Walensky said in late May.
Research shows the Pfizer/BioNTech and Moderna vaccines stay highly effective for at least six months (and counting).
But it’s not clear how long the protection provided by vaccines will last.
“We don’t know if it’s a year. We don’t know if it’s nine months. We don’t know if it’s two years yet,” board-certified internist Dr. Jorge Rodriguez said.
“Obviously, the people that were in the (vaccine trial) studies that started in October or so, they’re being followed on a regular basis” to help determine how long vaccine immunity lasts, Rodriguez said.

How long will we have to keep wearing masks?
“Fully vaccinated people can resume activities without wearing a mask or physically distancing, except where required by federal, state, local, tribal, or territorial laws, rules, and regulations, including local business and workplace guidance,” the CDC says.
But those who aren’t vaccinated should keep wearing masks in public places (especially indoors) and when it might be hard to keep distance from people who don’t live with you.
“It’s estimated that about 70% of Americans must be vaccinated before we get to herd immunity through vaccination. That’s the point where enough people have the immune protection that the virus won’t spread anymore,” said emergency medicine physician Dr. Leana Wen, a visiting professor at George Washington University Milken Institute School of Public Health.
“This means about 230 million Americans must receive the vaccine … At that point, we could probably see one another without masks — but not before.”
As of May 25, only about 131 million Americans — or about 39.5% of the US population — had been fully vaccinated, according to CDC data.

If I already had Covid-19, should I still get vaccinated?
“Yes, you should be vaccinated regardless of whether you already had COVID-19,” the CDC says.
“That’s because experts do not yet know how long you are protected from getting sick again after recovering from COVID-19.”
“There are actually six other coronaviruses – MERS and SARS and four other viruses that create the common cold. They don’t seem to do very well at creating long-term immunity,” epidemiologist Dr. Larry Brilliant said.
“Many of the vaccines that we’ve made in history are actually stronger than the virus is itself at creating immunity.”

How long will immunity last after getting a Covid-19 vaccine?
It’s too early to tell, the US Food and Drug Administration says.
The three vaccines currently used in the US were developed less than a year after Covid-19 was first detected in the US. The FDA said emergency authorization was swift, but it did not come at the cost of safety.
But since all Covid-19 vaccines are relatively new, it’s not clear exactly how long immunity from the vaccines will last.
“It may be that coronavirus vaccine becomes something that you have to get every year, like the flu vaccine,” emergency physician Dr. Leana Wen said.
Others say it’s possible you could go much longer without needing another Covid-19 vaccine — especially if enough people get vaccinated right now.
“The vaccine elicits such high levels of antibodies that even when confronted with a variant … there’s still meaningful protection,” said Dr. Scott Hensley, an immunologist at the University of Pennsylvania who has studied mRNA vaccines like Pfizer’s and Moderna’s for years.
“These mRNA vaccines – it really seems the level of antibodies they elicit are so high, they are persistent … I would not be surprised if this is a vaccine that we only get once.”
Vaccine trial participants are still being closely monitored. The Pfizer/BioNTech vaccine remains more than 91% effective against symptomatic Covid-19 for at least six months, the companies said. They said the vaccine also appeared to be fully effective against the worrying B.1.351 variant of the virus, which researchers feared had evolved to evade the protection of vaccines.

What are the side effects of the vaccines?
Some people have reported feeling temporary, flu-like symptoms. Don’t freak out if this happens to you, health experts say.
“These are immune responses, so if you feel something after vaccination, you should expect to feel that,” said Patricia Stinchfield of Children’s Hospitals and Clinics of Minnesota.
“And when you do, it’s normal that you have some arm soreness or some fatigue or some body aches or even some fever,” Stinchfield said. Some people may feel bad enough to need to stay home from work for a day, she said.
Read more about what to do if you do get side effects and why side effects are often a good sign.
The Pfizer/BioNTech vaccine has shown no serious safety concerns, Pfizer said. Pfizer has said side effects “such as fever, fatigue and chills” have been “generally mild to moderate” and lasted one to two days.
Moderna said its vaccine did not have any serious side effects. It said a small percentage of trial participants had symptoms such as body aches and headaches.
With the Johnson & Johnson vaccine, the most common side effects were pain at the injection site, headache, fatigue and muscle pain. While the CDC recommends the Johnson & Johnson vaccine, “women younger than 50 years old especially should be aware of the rare but increased risk of thrombosis with thrombocytopenia syndrome (TTS),” the agency says. “TTS is a serious condition that involves blood clots with low platelets. There are other COVID-19 vaccine options available for which this risk has not been seen.”

What is aerosolized spread? What’s the difference between aerosols and droplets?
Aerosolized spread is the potential for coronavirus to spread not just by respiratory droplets, but by even smaller particles called aerosols that can float in the air longer than droplets and can spread farther than 6 feet.
Respiratory aerosols and droplets are released when someone talks, breaths, sings, sneezes or coughs. But the main difference is size.
“If you have droplets that come out of a person, they generally go down within 6 feet,” said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases.
But aerosols (aka droplet nuclei) are smaller – less than 5 microns in diameter, according to the World Health Organization.
“Aerosol means the droplets don’t drop immediately,” Fauci said. “They hang around for a period of time.”
This becomes “very relevant” when you are indoors and there is poor ventilation, he said.
Multiple case studies suggest coronavirus can spread well beyond 6 feet through airborne transmission, such as during choir practices, said Dr. Amy Compton-Phillips, chief clinical officer of Providence Health System.
In Washington state, for example, 53 members of a choir fell sick and two people died after one member attended rehearsals and later tested positive for Covid-19.
In July, 239 scientists backed a letter urging public health agencies to recognize the potential for aerosolized spread.
“There is significant potential for inhalation exposure to viruses in microscopic respiratory droplets (microdroplets) at short to medium distances (up to several meters, or room scale), and we are advocating for the use of preventive measures to mitigate this route of airborne transmission,” the letter said.

How long does immunity last if you recover from Covid-19?
Research is still evolving, but a recent study examining antibodies suggests you could be immune for months after infection.
“Although this cannot provide conclusive evidence that these antibody responses protect from reinfection, we believe it is very likely that they will decrease the odds ratio of reinfection,” researchers from Mount Sinai wrote.
“It is still unclear if infection with SARS-CoV-2 [the scientific name for the novel coronavirus] in humans protects from reinfection and for how long.”
There have been some reports of people getting infected twice within several months. Doctors said a 25-year-old Nevada man appeared to be the first documented case of Covid-19 reinfection in the US. He was first diagnosed in April 2020, then recovered and tested negative twice. About a month later, he tested positive again.
A separate team of researchers said a 33-year-old man living in Hong Kong had Covid-19 twice, in March and August of 2020.
Last year, an 89-year-old Dutch woman – who also had a rare white blood cell cancer – died after catching Covid-19 twice, experts said. She became the first known person to die after getting reinfected.

More than 40% of US adults have at least one underlying condition that can put them at higher risk of severe complications, according to the CDC.
Those conditions include obesity, chronic obstructive pulmonary disease, heart disease, diabetes, and chronic kidney disease, according to the CDC.
People who have cancer, an organ transplant, sickle cell anemia, poorly controlled HIV or any autoimmune disorder are also at higher risk.
Covid-19 patients with pre-existing conditions — regardless of their age — are 6 times more likely to hospitalized and 12 times more likely to die from the disease than those who had no pre-existing conditions, CNN Chief Medical Correspondent Dr. Sanjay Gupta said.

Should we clean our cell phones daily?
Yes, that’s a good idea because cell phones are basically “petri dishes in our pockets” when you think about how many surfaces you touch before touching your phone.
You should regularly disinfect your mobile phone anyway, with or without a coronavirus pandemic.
“There’s probably quite a lot of microorganisms on there, because you’re holding them against your skin, you are handling them all the time, and also you’re speaking into them,” said Mark Fielder, a professor of medical microbiology at Kingston University.
“And speaking does release droplets of water just in normal speech. So it’s likely that a range of microbes – including Covid-19, should you happen to be infected with that virus – might end up on your phone.”

Is it safe to go back to the gym?
There are certainly risks if you’re not vaccinated.
Coronavirus often spreads more easily indoors rather than outdoors — especially if you’re indoors for an extended period of time.
Researchers have also found that heavy breathing and singing can propel aerosolized viral particles farther and increase the risk of transmission.
During one fitness instructor workshop, about 30 participants with no symptoms trained intensely for four hours, according to research published by the CDC. Eight participants later tested positive, and more than 100 new cases of coronavirus were traced back to that fitness workshop.
To help mitigate the risk, many gyms are limiting capacity or requiring masks.
And while health experts have recommended staying 6 feet away from others, it’s smart to keep even more distance than that at the gym.
“With all the heavy breathing, you may even want to double the usual 6 feet to 12 feet, just to be safe,” CNN Chief Medical Correspondent Dr. Sanjay Gupta said.

I heard you can get Covid-19 through your eyes. Should we wear goggles, too?
Doctors say wearing eye protection (in addition to face masks) could help some people, but it’s not necessary for everyone.
Teachers who have younger students in the classroom are “likely to be in environments where children might pull down their masks, or not be very compliant with them,” epidemiologist Saskia Popescu said. “There is concern that you could get respiratory droplets in the eyes.”
If you’re a health care worker or taking care of someone at home who has coronavirus, it’s smart to wear eye protection, said Dr. Thomas Steinemann, clinical spokesperson for the American Academy of Ophthalmology.
(Note: Regular glasses or sunglasses aren’t enough, because they leave too many gaps around the eyes.)
But if you’re vaccinated or not in a high-risk situation, wearing goggles isn’t necessary.
While it’s still possible to get Covid-19 through the eyes, that scenario is less likely than getting it through your nose or mouth, Steinemann said.
He said if a significant number of people were getting coronavirus through their eyes, doctors would probably see more Covid-19 patients with conjunctivitis, also known as pink eye (though having pink eye doesn’t necessarily mean you have coronavirus).

Should people wear face shields instead of (or in addition to) face masks?
The CDC does not recommend using plastic face shields for everyday activities or as a substitute for face masks. There are a few exceptions, such as for those who are hearing-impaired and rely on lip-reading or those who have physical or mental health conditions that would be exacerbated by wearing a cloth face mask.
“Cloth face coverings are a critical preventive measure and are most essential in times when social distancing is difficult,” the CDC says.
Clinical and laboratory studies show cloth face coverings reduce the spray of droplets when worn over the nose and mouth – what the CDC refers to as “source control.” And many people are contagious even when they don’t have any symptoms and don’t know they’re infected.
Face shields worn in addition to masks can provide an added layer of protection and can also help people stop touching their faces. Workers who are around people for long periods of time, such as grocery store workers or hospital personnel, may want to wear face shields in addition to masks, to increase their protection.
If someone must use a face shield without a mask, the CDC says the shield “should wrap around the sides of the wearer’s face and extend to below the chin. Disposable face shields should only be worn for a single use. Reusable face shields should be cleaned and disinfected after each use.”

To ease their mask fears, try buying or making masks with fun designs on them. Or have your child customize his or her own masks by drawing on them with markers.
You can also order children’s face masks with superheroes on them or show your kids photos of their favorite celebrities wearing masks.
It’s also important to set a good example by wearing a mask yourself. Show your children your own mask, and let them know that by wearing one, they’ll be just like Mom or Dad.

Are cancer patients at higher risk of severe complications from Covid-19?
Yes. And the increased risk applies to cancer patients of all ages, the CDC says.

Researchers found that patients whose cancer was getting worse or spreading were more than five times more likely to die in a month if they caught Covid-19.
But there are steps cancer patients can take to stay as healthy as possible:
- Make sure you have at least a 30-day supply of your medications.
- Don’t delay any life-saving treatment or emergency care during this pandemic.
- Talk with your healthcare provider about your individual level of risk based on your condition, your treatment, and the level of transmission in your community.
- Don’t stop taking your medicines or alter your treatment plan without talking to your healthcare provider.

Can central air conditioning spread Covid-19 in public places?
Technically, it can, but HVAC (heating/ventilation/air conditioning) systems are not thought to be a significant factor in the spread of coronavirus.
Many modern air conditioning systems will either filter out or dilute the virus. Ventilation systems with highly effective filters are a key way to eliminate droplets from the air, said Harvard environmental health researcher Joseph Gardner Allen.
Filters are rated by a MERV system – their “minimum efficiency reporting value” that specifies their ability to trap tiny particles. The MERV ratings go from 1 to 20. The higher the number, the better the filtration.
HEPA filters have the highest MERV ratings, between 17 and 20. HEPA filters are used by hospitals to create sterile rooms for surgeries and to control infectious diseases. They’re able to remove 99.97% of dust, pollen, mold, bacteria and other airborne particles as small as 0.3 microns.
For context, this coronavirus is thought to be between 0.06 to 1.4 microns in size.
But “HEPA filtration is not always going to be feasible or practical,” Allen said. “But there are other filters that can do the job. What is recommended now by the standard setting body for HVAC is a MERV 13 filter.”
High-efficiency filters in the 13-to-16 MERV range are often used in hospitals, nursing homes, research labs and other places where filtration is important.
“If you’re an owner of a home, building or mall, you want to have someone to assess your system and install the largest MERV number filter the system can reliably handle without dropping the volume of air that runs through it,” advised Erin Bromage, an associate professor of biology at the University of Massachusetts Dartmouth.
“In addition, virtually all modern air conditioning systems in commercial buildings have a process called makeup air where they bring in air from outside and condition it and bring it inside,” Bromage said. “It’s worse in regards to energy, but the more outside air we bring in, the more dilution of the virus we have and then the safer you are.”

How effective are different types of face masks? Which cloth masks work the best?
An N95 respirator provides the best protection. But throughout the pandemic, N95s have been in high demand and short supply.
As for other masks, different types have different levels of effectiveness, according to researchers at Florida Atlantic University.
They compared four types of face masks commonly used by the public: a stitched mask with two layers of fabric, a commercial cone mask, a folded handkerchief, and a bandana. Researchers tested each to see which would likely offer the most protection if someone coughed or sneezed.
— The stitched mask with two layers of fabric performed the best, with droplets traveling only 2.5 inches.
— With a cone-style mask, the droplets traveled about 8 inches.
— A folded handkerchief performed worse, with droplets traveling 1 foot, 3 inches.
— The bandana gave the least amount of protection of the cloth masks tested, with droplets traveling 3 feet.
— Still, any kind of cloth mask is better than none, the researchers found. Without any covering, droplets were able to travel 8 feet.
“People need to know that wearing masks can reduce transmission of the virus by as much as 50%, and those who refuse are putting their lives, their families, their friends, and their communities at risk,” said Dr. Christopher Murray, director of the University of Washington’s Institute for Health Metrics and Evaluation.

Can you get Covid-19 through sex?
The odds of transmitting coronavirus through sex hasn’t been thoroughly studied, though it has been found to exist in men’s semen.
But we do know Covid-19 is a highly contagious respiratory illness that can spread via saliva, coughs, sneezes, talking or breathing — with or without symptoms of illness.
So three Harvard physicians examined the likelihood of getting or giving Covid-19 during sex and made several recommendations.
For partners who haven’t been isolating together, they should wear masks and avoid kissing, the authors write.
In addition to wearing masks, people who have sex with partners outside of their home should also shower before and after; avoid sex acts that involve the oral transmission of bodily fluids; clean up the area afterward with soap or alcohol wipes to reduce their likelihood of infection.

If you do use a multi-stall public restroom, Nouri offers the following tips:
- Don’t use your freshly washed hands to turn off the water with the germ-laden faucet handle. Instead, use a paper towel to turn off the water and open the bathroom door. Throw away the paper towel immediately afterward.
- Wear a face mask. “Masks are one of the most effective ways to stop human-to-human transmission,” Nouri said. “If people in a public bathroom are not wearing masks, think twice before going in.”
- If the restroom looks crowded, wait until it clears out, if you can. “You’re reducing the risk of inhaling aerosolized particles from other people,” Nouri said.

Doctors strongly recommend performing CPR when someone needs it.
You could be hundreds of times more likely to save that dying person’s life than you are to die from Covid-19 if you contract it after performing CPR, according to a report published by a group of Seattle emergency room physicians in the journal Circulation.
But it’s important to act quickly for CPR to be effective.
“The chance of survival goes down by 10% for every minute without CPR,” said Dr. Comilla Sasson, vice president for science and innovation in emergency cardiovascular care at the American Heart Association. “It’s a 10-minute window to death in many cases.”
If you’re not certified in CPR, performing chest compressions could also buy more time until help arrives. Bystanders should “provide high-quality chest compressions by pushing hard and fast in the middle of the victim’s chest, with minimal interruptions,” the American Heart Association said.
If you’re not sure how “fast” to do to those chest compressions, singing any of these popular songs will help you get the right rhythm.

“Spraying or fumigation of outdoor spaces, such as streets or marketplaces, is also not recommended to kill the COVID-19 virus or other pathogens because disinfectant is inactivated by dirt and debris, and it is not feasible to manually clean and remove all organic matter from such spaces,” the WHO said.
“Moreover, spraying porous surfaces, such as sidewalks and unpaved walkways, would be even less effective.” Besides, the ground isn’t typically a source of infection, the WHO said.
And once the disinfectant wears off, an infected person could easily contaminate the surface again.

Hot water is best for killing bacteria and viruses in your laundry. But you don’t want to use that kind of scalding hot water on your skin.

Cold water will also work, “but you have to make sure you work really vigorously to get a lather and get everything soapy and bubbly,” said chemist Bill Wuest, an associate professor at Emory University. To do that, you might need to sing “Happy Birthday” three times instead of twice.
“Warm water with soap gets a much better lather – more bubbles,” Wuest said. “It’s an indication that the soap is … trying to encapsulate the dirt and the bacteria and the viruses in them.”

Are smokers or vapers at higher risk? What if I only smoke weed?
This is not a good time to be vaping or smoking anything, including weed.
“Vaping affects your lungs at every level. It affects the immune function in your nasal cavity by affecting cilia, which push foreign things out,” said Prof. Stanton Glantz, director of the Center for Tobacco Research Control and Education at University of California San Francisco.
When you vape, “the ability of your upper airways to clear viruses is compromised,” Glantz said.
Tobacco smokers are at especially high risk. In a study from China, where the first Covid-19 outbreak occurred, smokers were 14 times more likely to develop severe complications than non-smokers.
Even occasionally smoking marijuana can put you at greater risk.
“What happens to your airways when you smoke cannabis is that it causes some degree of inflammation, very similar to bronchitis, very similar to the type of inflammation that cigarette smoking can cause,” said pulmonologist Dr. Albert Rizzo, chief medical officer for the American Lung Association.
“Now you have some airway inflammation, and you get an infection on top of it. So yes, your chance of getting more complications is there.”

Does this pandemic have anything to do with the 5G network?
No. That’s just a hoax going around the internet.
“The theory that 5G might compromise the immune system and thus enable people to get sick from corona is based on nothing,” said Eric van Rongen, chairman of the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

My ex and I have joint custody of our kids. Is it safe for them to go between two homes?
Ideally, you should limit your children’s potential exposures to coronavirus and work out the safest plan possible with your ex.
The problem: Some state and county family courts might be closed, or open only for emergencies involving abuse or endangerment. So it might be difficult to formally modify pre-existing custody agreements.
But some states may be offering some flexibility during the pandemic. And there may be creative solutions, such as spending more time with one parent now in exchange for extra time with the other parent after the pandemic ends.

Should I wear a face mask in public? If so, how do I make one?
For unvaccinated people, the CDC “recommends wearing cloth face coverings in public settings where other social distancing measures are difficult to maintain (e.g., grocery stores and pharmacies).”
There are several key points:

If there’s no cure, why go to the hospital unless you have a breathing problem?
Most coronavirus patients don’t need to be hospitalized. “The vast majority of people – about 80% – will do well without any specific intervention,” said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases.
Those patients should get plenty of rest, hydrate frequently and take fever-reducing medication.
“The current guidance – and this may change – is that if you have symptoms that are similar to the cold and the flu and these are mild symptoms to moderate symptoms, stay at home and try to manage them,” said Dr. Patrice Harris, president of the American Medical Association.
But about 20% of coronavirus patients get advanced disease. “Older patients and individuals who have underlying medical conditions or are immunocompromised should contact their physician early in the course of even mild illness,” the CDC says.
The CDC also says you should get immediate help if you have:
- Trouble breathing
- Persistent pain or pressure in the chest
- Sudden confusion
- Bluish lips or face
“This list is not all inclusive,” the CDC says. “Please consult your medical provider for any other symptoms that are severe or concerning.”

Why are people stocking up on bottled water? Is the water supply at risk?
No, the water supply is not at risk.
“The COVID-19 virus has not been detected in drinking water,” the CDC says. “Conventional water treatment methods that use filtration and disinfection, such as those in most municipal drinking water systems, should remove or inactivate the virus that causes COVID-19.”
So there’s no need to hoard drinking water, said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases. Fauci said he and his wife are still drinking tap water.
Work/life myths & misinformation
How do I safely take care of someone who’s sick?
It may be difficult to know whether your loved one has coronavirus or another illness.
So it’s critical to play it safe and not infect yourself and, in turn, others. The CDC suggests:
- Giving the sick person their own room to stay in, if possible. Keep the door closed.
- Having only one person serve as the caretaker.
- Asking the sick person to wear a face mask, if they are able to. If the mask causes breathing difficulties, then the caretaker should wear a mask instead.
What are the symptoms?
Fatigue, fever, dry cough, difficulty breathing and the loss of taste or smell are some of the symptoms of Covid-19.
Symptoms can appear anywhere from 2 days to 2 weeks after exposure, the CDC says. But some people get no symptoms at all and can infect others without knowing it.
The illness varies in its severity. And while many people can recover at home just fine, some people — including young, previously healthy adults — are suffering long-term symptoms.
The stores are all out of disinfectant sprays and hand sanitizer. Can I make my own?
Yes, you can make both at home.
“Unexpired household bleach will be effective against coronaviruses when properly diluted” if you’re trying to kill coronavirus on a non-porous surface, the US Centers for Disease Control and Prevention said.
The CDC’s recipe calls for diluting 5 tablespoons (or ⅓ cup) of bleach per gallon of water, or 4 teaspoons of bleach per quart of water.
What you’ll need:
- 2/3 cup 91% isopropyl alcohol (rubbing alcohol)
- 1/3 cup aloe vera gel
- Mixing bowl
- Spoon or something for whisking
- Small container, such as a 3 oz. travel bottle
- Optional: essential oil to give your hand sanitizer a fragrance
In a mixing bowl, stir isopropyl alcohol and aloe vera gel together until well blended.
Add 8-10 drops of scented essential oil (optional, but nice). Stir.
Pour the homemade hand sanitizer into an empty container and seal.
Write “hand sanitizer” on a piece of masking tape and attach to the bottle.

Should I stock up on extra food and supplies?
Harvard Medical School recommends keeping a two-week to 30-day supply of nonperishable food at home. And if you don’t use them now, they may come in handy for power outages or extreme weather.
It’s also a good idea to keep at least a 30-day supply of prescription medications you may need, though it can be difficult to get them early. Consider mail-ordering medications.
Can I be fired if I stay home sick?
But there are exceptions. Employers who make workers with Covid-19 come in may be violating Occupational Safety and Health Administration [OSHA] regulations, said Donna Ballman, who heads an employee advocacy law firm in Florida.
What happens when workers don’t get paid sick leave?
But there is no federal mandate that requires companies to offer paid sick leave, and almost a quarter of all US workers don’t get it, according to 2019 government data. Some state and local governments have passed laws that require companies to offer paid sick leave.
The Family and Medical Leave Act (FMLA) can sometimes protect a worker’s job in the event they get sick, but it won’t guarantee they get paid while they’re out.
Employee advocates urge businesses to consider the special circumstances of the Covid-19, and some already have
Can managers send a sick worker home?
The Society for Human Resource Management recommends companies “actively encourage sick employees to stay home, send symptomatic employees home until they are able to return to work safely, and require employees returning from high-risk areas to telework during the incubation period (of 14 days).”
If a manager feels an employee’s illness poses a direct threat to colleagues’ safety, the manager may be able to insist the employee be evaluated by a doctor, said Alka Ramchandani-Raj, an attorney specializing in workplace safety.
If traveling on a plane, how do I stay safe?
Since Covid-19 is a respiratory disease, some airlines are now requiring passengers to wear face masks during the flight, except for while eating or drinking.
Health experts suggest eating, drinking and using the restroom before getting on the plane, to eliminate the need to take off your mask or go into a cramped lavatory on board.
And always be mindful of where your hands have been, travel medicine specialist Dr. Richard Dawood said.
Airport handrails, door handles and airplane lavatory levers are notoriously dirty.
“It is OK to touch these things as long as you then wash or sanitize your hands before contaminating your face, touching or handling food,” Dawood said.
“Hand sanitizers are great. So are antiseptic hand wipes, which you can also use to wipe down armrests, remote controls at your seat and your tray table.”

Since a plane’s cabin keeps circulating air, will I get sick if another passenger is sick?
Most viruses don’t spread easily on airplanes because of how the air circulates and is filtered, the CDC says.
Modern commercial jets recirculate 10-50% of the air in the cabin, mixed with outside air.
“The recirculated air passes through a series of filters 20-30 times per hour,” the CDC says.
“Furthermore, air generally circulates in defined areas within the aircraft, thus limiting the radius of distribution of pathogens spread by small-particle aerosols. As a result, the cabin air environment is not conducive to the spread of most infectious diseases.”
If I have a weakened immune system, should I cancel my travel plans?
People who are immunocompromised “are at higher risk from this illness, as well as other illnesses like the flu. Avoiding contact with ill people is crucial,” Washington state’s Snohomish Health District said.
“While rates of infection may not differ significantly between healthy and immunocompromised travelers, the latter are at greater risk for severe disease,” according to researchers from the Washington University School of Medicine.
What do I do if I think I’m sick?
Stay home. Call your doctor to talk about your symptoms and let them know you’re coming for an appointment so they can prepare for your visit, the CDC says.
Only a Covid-19 test can diagnose you with coronavirus, but if you suspect you have it, isolate yourself at home.
Many patients with coronavirus are able to recover at home. If you’ve been diagnosed and your illness is worsening, seek medical attention promptly. You may need to be monitored in a hospital.
Treatment & Prevention
Should I spray myself or my kids with disinfectant?
No. Those products work on surfaces but can be dangerous to your body.
There are some chemical disinfectants, including bleach, 75% ethanol, peracetic acid and chloroform, that may kill the virus on surfaces.
But if the virus is already in your body, putting those substances on your skin or under your nose won’t kill it, the World Health Organization says. And those chemicals can harm you.
Treatment & Prevention myths & misinformation
I’ve heard that home remedies can cure or prevent the virus. Is that true?
There’s no evidence from the outbreak that eating garlic, sipping water every 15 minutes or taking vitamin C will protect people from the new coronavirus. Same goes for using essential oils or colloidal silver.

Why waste a test kit on a person without symptoms?
Some people with coronavirus have mild or no symptoms. And in some cases, symptoms don’t appear until up to 14 days after infection.
During that incubation period, it’s possible to get coronavirus from someone with no symptoms. It’s also possible you may have coronavirus without feeling sick and are accidentally infecting others.

Why has the US been so far behind other countries with testing?
Experts said cuts in federal funding for public health and problems with early testing has forced the US to play catch-up.
Problems with public health infrastructure: Two years ago, the CDC stopped funding epidemic prevention activities in 39 countries, including China. This happened because the Trump administration refused to allocate money to a program that started during the 2014 Ebola outbreak.
Former CDC director Dr. Tom Frieden warned that move “would significantly increase the chance an epidemic will spread without our knowledge and endanger lives in our country and around the world.”
Problems with the testing: Malfunctions, shortages and delays in availability have all contributed to the slowdown.
In the first few weeks of the outbreak in the US, the CDC was the only facility in the country that could confirm test results — even though a World Health Organization test became available around the same time.
Some test kits that were sent around the country were flawed — a move that put the US behind about “four to five weeks,” says Dr. Rob Davidson, executive director of the Committee to Protect Medicare.

Did Dean Koontz predict this outbreak in the book “The Eyes of Darkness” almost 40 years ago?
No. There are some interesting coincidences in the 1981 fiction novel, which says “a severe pneumonia-like illness will spread around the globe” around the year 2020. Modern editions of the book call the biological strain “Wuhan-400,” and the current coronavirus outbreak started in Wuhan, China.
But there are important differences between the book and reality. The original version of the book called the strain the “Gorki-400,” in reference to a Russian locality, before it was later changed to the “Wuhan-400.” In the book, the virus was man-made, while scientists believe the novel coronavirus started in animals and jumped to humans. And in the book, the virus had a 100% mortality rate. Early estimates of the mortality rate for this coronavirus outbreak range from 2-4%.
