A virus, especially an “RNA virus” such as SARS-CoV-2, is expected to mutate and give rise to variants, some of which may be more easily transmitted. These variants may also be more or less effectively neutralized by the immune system since the mutations could alter the parts of the virus that are recognized by antibodies and T cells.

COVID-19 vaccination will protect most people from getting sick with COVID-19. A very small percentage of fully vaccinated people will still get COVID-19 if they are exposed to the COVID-19 virus. These are called vaccine breakthrough cases. Some people might not experience any symptoms and some people could become sick due to COVID-19.

Lysol is currently testing its other disinfecting products. Until we are able to provide a result, the EPA has listed other Lysol disinfectants that are effective against similar human coronaviruses or that meet the EPA Viral Emerging Pathogen Policy 2 (List N). These Lysol products meet their criteria, and can be used against the COVID-19 virus.
COVID-19 is caused by infection with a coronavirus first identified in 2019, and flu is caused by infection with influenza viruses. COVID-19 seems to spread more easily than flu. However, as more people become fully vaccinated against COVID-19, the spread of the virus that causes COVID-19 should slow down.
Despite the lack of evidence that the flu shot can protect you against the coronavirus, the authors of the Brazil study and other medical experts agree that it's important for the public to get the...

A person who contracts COVID-19 in their 70s has an 8 percent chance of dying, and a person in their 80s a nearly 15 percent chance of dying. The virus can be lethal in a variety of ways. Viral infections in the lungs can trigger an immune response so strong that it fatally damages the lungs.
To interpret any data on confirmed cases we need to know how much testing for COVID-19 the country actually does. The Our World in Data COVID-19 Testing dataset Because testing is so very crucial to understanding the spread of the pandemic and responding appropriately, we have focused our efforts on building a global dataset on COVID-19 testing.
