Is coronavirus disease contagious?

The virus that causes COVID-19 is spreading from person-to-person. People are thought to be most contagious when they are symptomatic (the sickest). That is why CDC recommends that these patients be isolated either in the hospital or at home (depending on how sick they are) until they are better and no longer pose a risk of infecting others. More recently the virus has also been detected in asymptomatic persons.

Can coronavirus survive in hot weather?

Generally coronaviruses survive for shorter periods at higher temperatures and higher humidity than in cooler or dryer environments. However, we don't have direct data for this virus, nor do we have direct data for a temperature-based cutoff for inactivation at this point. The necessary temperature would also be based on the materials of the surface, the environment, etc.

Can you contract the coronavirus disease from a package in the mail?

Coronaviruses are generally thought to be spread most often by respiratory droplets. Currently there is no evidence to support transmission of COVID-19 associated with imported goods and there have not been any cases of COVID-19 in the United States associated with imported goods.

Is it possible to be infected with the coronavirus disease through food?

Current evidence on other coronavirus strains shows that while coronaviruses appear to be stable at low and freezing temperatures for a certain period, food hygiene and good food safety practices can prevent their transmission through food.

Are children at risk for getting coronavirus disease?

Information about COVID-19 in children is somewhat limited, but current data suggest children with COVID-19 may have only mild symptoms. However, they can still pass this virus onto others who may be at higher risk, including older adults and people who have serious underlying medical conditions.

Can coronavirus be transmitted by touching a contaminated surface?

It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads.

How long can the novel coronavirus live on surfaces?

A recent study by the National Institutes of Health found that the coronavirus survives on a variety of different surfaces, including: In aerosols, for up to 3 hours On copper, for up to 4 hours On cardboard, for up to 24 hours On stainless steel and plastic, for up to 3 days
