If the virus can copy itself and hijack enough of your cells without being wiped out by your immune system, that's how you get sick. Every now and then, an error occurs during the virus's copying process. That's a mutation.

Common questions

Is the virus that causes COVID-19 mutating?
Severe acute respiratory syndrome coronavirus 2, the virus that causes coronavirus disease 2019 (COVID-19), is accumulating genetic mutations that may have made it more contagious, according to a study published in mBIO.
What is the name of the virus that causes COVID-19?
The virus responsible for the COVID-19 pandemic, SARS-CoV-2, is part of a large family of coronaviruses. Coronaviruses usually cause mild to moderate upper-respiratory tract illnesses, like the common cold. However, SARS-CoV-2 can cause serious illness and even death.
Is the flu different from COVID-19?
Influenza (Flu) and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. COVID-19 is caused by infection with a new coronavirus (called SARS-CoV-2) and flu is caused by infection with influenza viruses.
Where did the coronavirus disease come from?
Experts say SARS-CoV-2 originated in bats. That's also how the coronaviruses behind Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS) got started. SARS-CoV-2 made the jump to humans at one of Wuhan's open-air “wet markets.”
