What you should do if you or a loved one tests positive for Covid-19

(CNN) President Donald Trump and First Lady Melania Trump have tested positive for Covid-19 and must isolate themselves from others, including members of their own family.

It's a scary reality so far shared by more than 34 million people -- including 7 million Americans -- and the numbers are growing daily.

The President and First Lady will be surrounded by 'round-the-clock care by the best doctors in America.

But what do you do if you or a loved one tests positive for Covid-19? That will depend on a number of factors -- If you are having trouble breathing or are elderly and fragile, you may be immediately hospitalized.

If you're not in immediate danger but potentially higher risk -- you have underlying health conditions, such as diabetes, hypertension or lung issues; you're over 60; pregnant, obese or immune-compromised -- you should keep in daily contact with your physician while isolating at home.

If you have mild symptoms but no additional known risk factors you will likely be told to stay home, rest and drink plenty of fluids, all while still keeping a close eye on how you feel.

"People who are mildly ill with Covid-19 are able to recover at home," the US Centers for Disease Control and Prevention says. "Do not leave, except to get medical care."

Be sure to get care if you feel worse or you think it is an emergency, the CDC adds, but call first. And don't use public transportation, ride-sharing or taxis to get there.

Now what? Are you prepared to take care of yourself if you're alone? What can you do to protect other family members who have been exposed and will have to stay home with you?

Prepare in advance

Preparation is the key to a good plan.

Before anyone in your family or community gets sick, the CDC suggests checking in with loved ones, relatives, neighbors and friends to exchange phone numbers and emails and to find out if anyone will have special needs if they get sick. Have a list of your own emergency numbers handy. It should include your health care provider, local public health department, local hospital and ambulance service.

Parents and guardians should plan well in advance by setting up a structure in which all kids and potential caregivers know their roles and expectations, said pediatrician Dr. Tanya Altmann, Editor-in-Chief of the American Academy of Pediatrics' book "Caring for Your Baby and Young Child: Birth to Age 5 and The Wonder Years."

"Many parents are going to get sick," Altmann said. "So what's the game plan? How are we going to isolate them and who's going to be the backup parent? You need to know what to do so you're not panicked and struggling if one parent gets a fever in the middle of the night."

If you haven't accomplished these tips by the time you've tested positive, do it now or ask a loved one to help.

Hopefully, you've been following standard hygiene practices before your illness. These are behaviors we should all be doing daily, automatically, to protect ourselves from germs, colds and flu.

Avoid touching your eyes, nose and mouth with unwashed hands; cough and sneeze into elbows or tissues that you immediately throw away, and regularly wash, wash, wash those hands with warm water and lots of soapy bubbles.

Check out this proper handwashing technique to try while singing along to a song. (If you're tired of "Happy Birthday," here are some cool tunes you can substitute.) When you can't use soap and water, use hand sanitizer that is at least 70% alcohol and rub thoroughly.

The CDC says you should also have also been cleaning frequently touched surfaces daily with a regular household cleaner followed by a disinfectant. In addition to bathroom surfaces, tables and countertops, don't forget light switches, faucets and sinks, cabinet handles, doorknobs, phones and keyboards.

Social distancing is critical to containing the virus before and after infection: Stay and work from home if that's possible, and limit contact with others -- no cookouts, no playdates, no face-to-face dates.

And if you have to leave isolation for life's necessities, such as food and outdoor exercise, wear a three-ply mask and stay at least 6 feet away from others. (Make sure you can eyeball how long six feet actually is.)

Stock up in advance

Don't hesitate to order online or ask loved ones to provide basic supplies:

  • A working thermometer to monitor fever, which is considered to be 100 degrees Fahrenheit (37.7 degrees Celsius), and a method to clean it, such as Isopropyl alcohol
  • Fever-reducing medications, such as acetaminophen
  • A box of rubber or latex disposable gloves and face masks.
  • A 60- or 90-day supply of necessary prescription medicines
  • Regular soap and 70% alcohol-based hand sanitizer (antibacterial soap isn't necessary if you wash properly, and that way you won't contribute to the world's growing antibiotic-resistant superbugs)
  • Tissues to cover sneezes and coughs. But there's really no need to hoard toilet paper -- this is a respiratory disease.
  • Regular cleaning supplies, kitchen cleaning gloves and trash can liners
  • Disinfectant cleaning supplies -- the CDC suggests picking from a list that meets the virus-fighting standards of the US Environmental Protection Agency, but says you can also make your own version by using 1/3 cup unexpired bleach per gallon of water or 4 teaspoons bleach per quart of water. Never mix bleach with ammonia or any other cleanser -- it produces toxic gases.

Isolate yourself or loved one

Once your healthcare provider tells you Covid-19 is confirmed or even suspected without a test, the CDC says you or your loved one should stay in a separate room (preferably with a private bathroom) away from other people in the household.

If you live alone, that's not difficult. Your challenge is to monitor your symptoms and care for yourself when you're not feeling well. Be sure to have a plan in place to get food and medications delivered to your home, and find someone who can be responsible for virtually checking in on you on a regular basis.

Stock or ask loved ones to provide the room with all relevant forms of entertainment: TV, computer, iPad, books, even games that you could play via FaceTime or Skype.

If you are part of a family, staying isolated can be challenging, especially if you are in a small space or there are children in the home.

"If you have somebody at home who's older or immunocompromised, you may want to isolate them to one side of the house so the kids and everybody else aren't around them on a regular basis," Altmann said.

"If it's a child that you have to care for, then you may have to make the decision to isolate one adult with the child," she added. "That adult would be caring for the child, and the other adult would be responsible for the rest of family."

And of course all of this will be extremely difficult for a single parent "who might be the only one," said pediatrician Dr. Jenny Radesky, a spokesperson for the American Academy of Pediatrics.

"Know who your neighbors are, even what your neighborhood social network might be," said Radesky, an assistant professor of pediatrics at the University of Michigan. "You may not be that close interpersonally, but someone may be willing to do a grocery store drop-off, or pick-up medications because we're all in this together."

The rest of the family should practice isolation as well, Radesky added.

"Unfortunately you need to keep the whole household under isolation," she said. "The patterns of Covid-19 spread suggest that clusters of people who live close together are at highest risk of getting it from one another. If children are part of that household, they may show minimal symptoms but still be contagious."

Cover up and disinfect

If you're sick, the CDC says to use a face mask around other people, such as when going to the doctor or hospital.

Try to keep it on at home too, unless you or your loved one is having "trouble breathing" or is "unconscious, incapacitated, or otherwise unable to remove the mask without assistance," the CDC says.

Altmann stresses maximizing isolation and protective actions.

"You can have a healthy person leave the sick one food and drinks at the door, and then go wash their hands," Altmann explained. "Wear gloves to pick up the empty plates, take them back to the kitchen and wash them in hot water with soap, or preferably with a dishwasher, and wash your hands again."

Do not share drinking glasses, cups, forks or other eating utensils or dishes, the CDC says. Don't share towels or bedding with other people in your home. When doing laundry, don't shake the sick person's dirty clothes to "minimize the possibility of dispersing virus through the air."

And caregivers should wear disposable gloves when handling that dirty laundry, the CDC says, throwing them away after each use.

"If using reusable gloves, those gloves should be dedicated for cleaning and disinfection of surfaces for Covid-19 and should not be used for other household purposes. Clean hands immediately after gloves are removed," the CDC advises.

Dedicate a lined trash can for any tissues or other paper or disposable products used by a sick person, the CDC says, adding that caregivers should "use gloves when removing garbage bags, handling and disposing of trash. Wash hands after handling or disposing of trash."

And remember: Call 911 immediately if you or your loved ones have any of these symptoms: increased or sudden difficulty breathing or shortness of breath; a persistent pain or pressure in the chest; and any sign of oxygen deprivation, such as new confusion, bluish lips or face, or you can't arouse the sick person.

While these are key danger signs, this is not an exhaustive list, says American Medical Association president Dr. Patrice Harris, so call if anything concerns you.

"If the symptoms don't get better or they worsen you should call your health care provider, the urgent care or the emergency department," Harris said. "And if the shortness of breath is severe, immediately call 911."

Keeping everyone else from getting sick

To be clear: After a positive Covid-19 diagnosis, everyone in the house needs to isolate themselves from the outside world as much as possible.

"I would recommend that families find friends who can drop off essential groceries or medications, not go to work, and not play with other children -- even outside," Radesky said.

"If you don't have friends who can drop off groceries or essential items, see if the local stores can deliver the items for you -- I'm sure they would appreciate not having a potential Covid-19 exposure in their store," she added.

If a family member without symptoms believes it is absolutely essential to go outside to the grocery store, pharmacy or to check on a family member, be aware that you may well be contagious and anything you touch could transfer the virus -- even without symptoms,

"I would urge people not to do this," Radesky said. "The way we will beat this virus is by reducing the number of times that each infected person transmits the virus to another person. So the more you can do to stop the virus in its tracks -- in other words, your family doesn't give it to anyone else, and you don't bring it to your workplace or a local store -- the sooner we will be done with this!"

To reduce virus transfer inside your home, try to keep an air flow in the rest of the home with opened windows or doors with screens, if weather permits. You can also add air filtering devices to your home.

"Improving ventilation helps remove respiratory droplets from the air," the CDC says.

Have everyone wash their hands at every opportunity. Clean and disinfect all those commonly shared surfaces -- don't forget the refrigerator and microwave handles!

Keep everyone as stress free as possible -- a hard task for sure -- and focus on healthy eating, regular exercise and quality sleep.

Even though there is no indication that pets can give or get Covid-19, the CDC suggests keeping pets away from sick people.

"Since animals can spread other diseases to people, it's always a good idea to practice healthy habits around pets and other animals," the CDC says. "If you must care for your pet or be around animals while you are sick, wash your hands before and after you interact with pets."

When is your home isolation over?

If you tested positive but had no symptoms, you can stop isolating at home 10 days after the date you had your positive test, the CDC says.

If you did have symptoms, the CDC adds, you can stop isolating when you meet three criteria:

  • At least 10 days have passed since symptoms first appeared
  • AND you been free of fever for 24 hours without taking any fever-reducing medications
  • AND any other symptoms of Covid-19 are improving

The CDC notes that a loss of taste and smell can remain for weeks or even months after recovery, but that does not mean you need to remain isolated.

However, if you were more severely sick with Covid-19 -- such as being admitted to a hospital and needing oxygen -- the rules change, according to the CDC:​

"Your healthcare provider may recommend that you stay in isolation for longer than 10 days after your symptoms first appeared (possibly up to 20 days)," the CDC says.

These are scary times, but hopefully these tips will help ease your anxiety and prepare you and your family for the worst, while hoping and striving for the best.
