There is a surge of COVID-19 infections happening across the U.S. Midwest, including many of the communities served by Mayo Clinic Health System in Wisconsin, Iowa and Minnesota. Some of those locations have activated hospital emergency surge plans to manage the number of patients hospitalized with COVID-19 infections.
As the COVID-19 pandemic continues, with dire news about upward pandemic trends, it may be tempting to believe inaccurate, questionable claims. Perhaps you’ve heard theories about COVID-19 on social media, or from friends and family members?
Let’s set the record straight about myths.
Myth: Spikes in COVID-19 cases are because of increased testing.
Fact: The rise in infections is not related to increased testing. Of greater concern than the number of tests performed is the increase in the percentage of positive results. This means that the virus is quickly spreading in communities. Learn about the different types of COVID-19 tests.
COVID-19 testing is critical, as it helps people make decisions to self-isolate and guides health care providers’ decisions for medical treatment. Widespread testing also allows local health departments to monitor the virus’ spread, and make recommendations to schools and businesses.
Myth: We can achieve herd immunity by letting the virus spread through the population.
Fact: Herd immunity occurs when a large portion of a community (the herd) becomes immune to a disease, making the spread of disease from person to person unlikely. As a result, the whole community becomes protected — not just those who are immune. There are some significant problems with relying on community infection to create herd immunity to the virus that causes COVID-19. First, it isn’t yet clear if infection with the COVID-19 virus makes a person immune to future infection. If it does not create immunity, herd immunity will not work.
Even if COVID-19 infection creates long-lasting immunity to SARS-CoV-2, the virus that causes COVID-19, a large number of people would have to become infected to reach the herd immunity threshold. Experts estimate that 70% of the population in the U.S. — more than 200 million people — would have to recover from COVID-19 to halt the epidemic. This amount of infection also could lead to serious, and potentially long-term, complications and millions of deaths. If many people become sick with COVID-19 at once, the health care system could quickly become overwhelmed.
Myth: Cold weather and snow can kill COVID-19.
There is no scientific evidence to believe colder weather can kill COVID-19 or other viruses. The normal human body temperature remains around 36.5 C to 37 C, regardless of the external temperature or weather.
Use these practices to reduce the spread of COVID-19 in our communities:
• Wear a mask in public. I wear a mask to protect you. You wear a mask to protect me.
• Keep your physical distance — 6 feet or about two arms’ lengths apart from other people.
• Avoid in-person gatherings.
• Wash your hands with soap and water. It’s simple and effective.
• Stay home if you do not feel well.
• Get a test if you have COVID-19 symptoms. Call your local health care provider to schedule a test.
• Self-isolate if you have been around someone who is sick or tested positive.
Myth: COVID-19 is no worse than the seasonal flu.
Fact: During the COVID-19 pandemic, you may have heard that COVID-19 is similar to the flu. It is true both are contagious respiratory diseases caused by viruses, and people with COVID-19 and the flu may share some common symptoms.
However, after closer comparison, the viruses have been found to affect people differently and have differences. Symptoms of COVID-19 and the flu appear at different times. COVID-19 symptoms generally appear two to 14 days after exposure. Flu symptoms usually appear about one to four days after exposure. With COVID-19, you may experience loss of taste or smell.
COVID-19 appears to be more contagious and spread more quickly than the flu. Severe illness, such as lung injury, may be more frequent with COVID-19 than with influenza. The death rate also appears to be higher with COVID-19 than the flu. COVID-19 can cause different complications than the flu, such as blood clots and multisystem inflammatory syndrome in children.
Another difference is the flu can be treated with antiviral drugs. No antiviral drugs are currently approved and available to treat COVID-19. Researchers are evaluating many drugs and treatments for COVID-19. Some drugs may help reduce the severity of COVID-19.
Myth: I’m currently taking an antibiotic, so this may prevent or treat COVID-19.
Fact: Antibiotics treat only bacteria, not viruses. COVID-19 is caused by a virus. Therefore, antibiotics should not be used for prevention or treatment. However, some people who are hospitalized for COVID-19 may receive antibiotics because they have a different bacterial infection at the same time.
Myth: Fabric masks don’t protect yourself or others from COVID-19.
Fact: Simply put, wearing a cloth mask helps decrease the spread of COVID-19. Research shows that a significant number of people with COVID-19 lack symptoms or are considered asymptomatic. These people may not know they are transmitting the virus to others when they talk, sneeze, cough or raise their voice (e.g., singing or shouting). You should wear a cloth mask to reduce the chance of transmitting respiratory droplets (spit) to others around you. You should wear a mask to protect others, and they should wear a mask to protect you.
Myth: Children who develop COVID-19 don’t become critically ill.
Fact: Most children with COVID-19 have mild symptoms or no symptoms at all. However, some children get severely ill from COVID-19. They might require hospitalization, intensive care or a ventilator to help them breathe. In rare cases, they may die.
Although the CDC reports fewer children have been sick with COVID-19 compared with adults, children can be infected and become ill with the virus that causes COVID-19, and also spread the virus to others. Children, like adults, who have COVID-19 but have no symptoms (asymptomatic) can still spread the virus to others.
