Prevention and self-care
The COVID-19 vaccine is still the optimal way to protect yourself against COVID-19 infection, however there are additional medications available to help lower your risk of becoming infected with the virus. Our COVID-19 treatment and preventative medicine page provides information about your options.
If you think you might have COVID-19, there are steps you can take to help prevent the virus from spreading to others in your home and community, including:
- Get tested for COVID-19 and act as if you have the virus until you receive a negative result.
- Stay away from others if you have symptoms.
- Wear a mask that covers your nose and mouth while you are near others.
The best way to protect yourself and others from COVID-19 is by getting the COVID-19 vaccine and any boosters when eligible. Also, take these steps to avoid exposure to the virus:
- Avoid close contact with people who are sick.
- Avoid touching your eyes, nose, and mouth.
- Practice "social distancing." Stay at least six feet away from other people.
- Clean and disinfect high-touch objects and surfaces (counters, tabletops, doorknobs, bathroom fixtures, toilets, phones, keyboards, tablets and bedside tables, light switches) using a regular household cleaning spray or wipe.
- Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom, before eating, and after blowing your nose, coughing, or sneezing. If soap and water are not available, use an alcohol-based hand sanitizer with at least 60 percent alcohol.
- Because infected people can transmit the virus to others before showing symptoms, the CDC recommends wearing face coverings in public settings where other social distancing measures are difficult to maintain (e.g., grocery stores and pharmacies) especially in areas of significant community-based transmission.
In addition, to help prevent the spread of the disease to others and prepare for possible infection:
- Stay home when you are sick.
- Cover your cough or sneeze with a tissue (and then dispose of this) or your elbow.
- Contact your health care provider to ask about getting an extra supply of your regular prescription medicines to have on hand if there is an outbreak of COVID-19 in the community and you need to stay home for a long period of time.
- Be sure you have over-the-counter medicines and supplies (tissues, etc.) to treat fever and other symptoms. Most people will be able to recover from COVID-19 at home.
- Keep household items and groceries on hand so that you will be prepared to stay at home for a period of time.
The CDC has excellent advice to help prevent household members from getting infection if someone in the home has COVID-19. These include sleeping in separate rooms, using separate bathrooms if possible, frequent hand washing, and staying more than six feet away from the infected person.
Let your health care provider know right away if you are aware of having contact with a person who has tested positive for COVID-19. Your provider can determine if you need testing and provide more education on how to prevent further risk of infection to you and to prevent spread of infection to others.
If you test positive for COVID-19, the CDC recommends that you stay home for five days, regardless of your vaccination status. If you have no symptoms or your symptoms have resolved after five days, you can leave your house. You should continue to wear a mask around others for five additional days. If you have a fever, continue to stay home until your fever resolves.
If you cannot find a place to get tested, and do not have access to an at-home antigen test, you should assume your symptoms are likely to be from COVID-19. Isolate in accordance with CDC guidance and talk to your healthcare provider.
Individuals with COVID-19 can breastfeed if they wish to do so. They should:
- Practice respiratory hygiene during feeding, wearing a mask where available.
- Wash hands before and after touching the baby.
- Routinely clean and disinfect surfaces they have touched.
Being immunocompromised means that your immune system’s defenses are low, affecting its ability to fight off illness and infection, including COVID-19. Certain conditions like autoimmune diseases (i.e., lupus, rheumatoid arthritis, and Type 1 diabetes), your age, and a history of smoking could increase the chance of infection. Medical treatments, such as cancer treatments and organ and bone marrow transplants, can also weaken or suppress the immune system.
If you're immunocompromised, it’s especially important to protect yourself by getting vaccinated, wearing a mask, washing your hands, frequently disinfecting high-touch surface areas, and practicing social distancing. Penn Medicine has also put many safety measures in place throughout our locations to reduce the risk of COVID-19 exposure to even our most vulnerable patients.
The CDC has detailed advice regarding travel. If you travel, take the following routine precautions:
- Avoid contact with sick people.
- Avoid touching your eyes, nose, or mouth with unwashed hands.
- Clean your hands often by washing them with soap and water for at least 20 seconds or using an alcohol-based hand sanitizer—especially after going to the bathroom, before eating, and after coughing, sneezing, or blowing your nose.
- Make sure you are up-to-date with your vaccinations.
For symptom management, we recommend acetaminophen (Tylenol) to control fever or pain. If Tylenol doesn’t help your symptoms, NSAIDs such as ibuprofen (Motrin, Advil) or naproxen (Aleve, Naprosyn) can be used, but only at recommended doses.
No supplements or medications have been shown to reduce the risk of contracting COVID-19. The best way to prevent COVID-19 is to practice social distancing, to wash your hands regularly, and to wear a mask when in public.
Ultraviolet (UV) rays are part of sunlight. Studies show that UV light can be used to eliminate airborne COVID-19 particles and disinfect surfaces. For this reason, some hospitals, subways, and other public locations are using UV light to help disinfect areas when they are not occupied by people. While helpful for cleaning these areas, UV light has not been shown to prevent COVID-19 infection in humans or to eliminate the virus in infected patients. The safety and efficacy of many UV light devices sold to the public are not routinely reviewed, so these should be used with caution. Overexposure to ultraviolet rays can have harmful health effects and is a major risk factor for cancer. For these reasons, you should wear sunscreen on exposed skin when you’re in the sun for long periods.
Smoking marijuana, nicotine, or vape e-cigarettes leads to damage to lungs and airways that may put you at further risk of harm from a COVID-19 infection. Cannabis and nicotine are among many substances currently being studied in the context of COVID-19, but no data are available yet. In the interim, the harms of smoking to your airways are well-established in the medical literature.
Vitamin D is among the many medications being studied in the prevention and treatment of COVID-19. However, researchers are still trying to evaluate vitamin D's role in preventing or treating COVID-19. There are no established recommendations for its use at this time. It’s important to discuss with your physician whether vitamin D supplementation may be appropriate for you.
There are many physical and mental health benefits of regular exercise. Exercise is important to maintain health, prevent weight gain, reduce stress and anxiety, and improve sleep. Some studies even show that regular, moderate-intensity exercise may have immune-boosting benefits, but the impact of exercise on susceptibility to COVID-19 is not known.
If you have any chronic medical conditions or have not exercised in a while, it’s best to check with your physician before picking up a new exercise regimen.
