See full answer COVID-19 is a new disease and we are still learning how it spreads. The virus that causes COVID-19 is thought to mainly spread from close contact (i.e., within about 6 feet) with a person who is currently sick with COVID-19. The virus likely spreads primarily through respiratory droplets produced when an infected person coughs or sneezes, similar to how influenza and other respiratory infections spread. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. This type of spread is not a concern after death. 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.
COVID-19 is caused by a coronavirus called SARS-CoV-2. Coronaviruses are a large family of viruses that are common in people and may different species of animals, including camels, cattle, cats, and bats. Rarely, animal coronaviruses can infect people and then spread between people. This occurred with MERS-CoV and SARS-CoV, and now with the virus that causes COVID-19.
Plan and Prepare. Frequently wash hands with soap and water for at least 20 seconds. If soap and water are not readily available use hand sanitizer with at least 60% alcohol. Cover coughs and sneezes with a tissue or use the inside of your elbow. Clean frequently touched objects and surfaces. Stay home when sick.
A recent study found that the COVID-19 coronavirus can survive up to four hours on copper, up to 24 hours on cardboard, and up to two to three days on plastic and stainless steel.
Information about COVID-19 in children is somewhat limited, but current data suggest children with COVID-19 may only have 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.
