Debunking common COVID-19 myths

The current COVID-19 pandemic is a quickly evolving situation, and ever-changing information about the disease can be confusing. When it comes to protecting yourself from COVID-19 and how the virus behaves, it’s important to know what is true and what is not. Here are some myths you might have come across, along with the facts that clear up those myths.

Myth: If I wear a cloth face covering/homemade mask, it’s fine for me to resume normal activities and I’m safe to go out to public spaces.
Fact: Wearing a mask can help slow the spread, but we should still practice social distancing, staying at least six feet away from others when not at home.

Myth: A vaccine to cure COVID-19 is available.
Fact: There is no vaccine for the novel coronavirus right now. Researchers are working hard to develop a vaccine that is safe and effective for humans, but that will take many months. 

Myth: The novel coronavirus was deliberately created or released.
Fact: Viruses can change over time. It is likely that the coronavirus began as a disease in a common animal, such as a pig, bat, or bird, and underwent a change that allowed it to pass to humans.

Myth: Handwashing only kills coronavirus if you use hot water.
Fact: Washing your hands with hot water isn't any more effective than with cold water. Washing your hands often with soap and water is recommended as one of the best ways to limit the spread of the coronavirus, but the temperature of the water doesn't matter. It's the scrubbing action that cleans your hands. Wash your hands with soap and water for at least 20 seconds.

Myth: Hand dryers can kill COVID-19.
Fact: It’s been shown with other viruses that hand dryers actually increase the air circulation of viruses as that air blows on your hands. Whenever possible, avoid hand dryers and use clean paper towels instead.

Myth: Rinsing your nose with saline can help prevent infection with COVID-19.
Fact: Although nasal rinses can help with sinusitis and with allergies, there’s no direct evidence that they kill the novel coronavirus.

Myth: Antibiotics can kill COVID-19.
Fact: COVID-19 is caused by the novel coronavirus, and no antibiotic can kill a virus. Antibiotics should be used only in cases of a known, documented bacterial infection.

Myth: Lots of vitamin C will ward off COVID-19.
Fact: There is no evidence that taking extra vitamin C will fight against COVID-19.

Myth: Like colds and flu, COVID-19 will fade with warmer weather.
Fact: Because the novel coronavirus is exactly that—novel, or new—there is a lot researchers still don’t know about how it behaves. One recent study suggests that coronavirus might prefer cooler climates and spreads more slowly in warmer climates, but it’s too early to tell.

Myth: Drinking lots of water can prevent COVID-19.
Fact: This rumor is based on the idea that water “washes” the virus into the acidic environment of the stomach, but there’s no basis for that idea. It’s always a good idea to stay hydrated, and if you’re sick, it’s important to drink fluids and rest to speed up recovery.

Myth: Rural communities don't need to worry about COVID-19 because of their sparse populations.
Fact: This is a dangerous myth. Everyone needs to take steps, including social distancing and frequent hand washing, to slow the spread of this serious disease.
