Coronavirus Disease 2019: Myth vs. Fact

Reviewed By:

There's a lot of information circulating about COVID-19, the disease caused by the new coronavirus, so it’s important to know what’s true and what’s not. Lisa Maragakis, M.D., M.P.H., senior director of infection prevention at Johns Hopkins, helps clarify information to help keep you and your family healthy and safe.

TRUE or FALSE? A vaccine to cure COVID-19 is available.

The answer is false.

There is no vaccine for the new coronavirus right now. Scientists have already begun working on one, but developing a vaccine that is safe and effective in human beings will take many months.

TRUE or FALSE? You can protect yourself from COVID-19 by swallowing or gargling with bleach, taking acetic acid or steroids, or using essential oils, salt water, ethanol or other substances.

The answer is false.

None of these recommendations protects you from getting COVID-19, and some of these practices may be dangerous. The best ways to protect yourself from this coronavirus (and other viruses) include:

Washing your hands frequently and thoroughly, using soap and hot water.

Avoiding close contact with people who are sick, sneezing or coughing.

In addition, you can avoid spreading your own germs by coughing into the crook of your elbow and staying home when you are sick.

TRUE or FALSE? The new coronavirus was deliberately created or released by people.

The answer is false.

Viruses can change over time. Occasionally, a disease outbreak happens when a virus that is common in an animal such as a pig, bat or bird undergoes changes and passes to humans. This is likely how the new coronavirus came to be.

TRUE or FALSE? Ordering or buying products shipped from overseas will make a person sick.

The answer is false.

Researchers are studying the new coronavirus to learn more about how it infects people. As of this writing, the World Health Organization (WHO) says that the likelihood of becoming infected with COVID-19 from a commercial package is low since it has likely traveled over several days and been exposed to different temperatures and conditions during transit.

TRUE or FALSE? A face mask will protect you from COVID-19.

The answer is false.

Certain models of professional, tight-fitting respirators (such as the N95) can protect health care workers as they care for infected patients.

For the general public without respiratory illness, wearing lightweight disposable surgical masks is not recommended. Because they don’t fit tightly, they may allow tiny infected droplets to get into the nose, mouth or eyes. Also, people with the virus on their hands who touch their face under a mask might become infected.

People with a respiratory illness can wear these masks to lessen their chance of infecting others. Bear in mind that stocking up on masks makes fewer available for sick patients and health care workers who need them.
