COVID-19 is the name of the disease caused by the new coronavirus that is called SARS-CoV-2, or sometimes just "novel coronavirus".
the incubation period may range from 2–14 days.
Coronaviruses are members of the coronavirus family of viruses — one of the many families that include viruses able to infect people and animals. Seven members of the coronavirus family can make people ill, one of which is the new coronavirus strain SARS-CoV-2, which causes COVID-19.
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.
At this time, there is no evidence that companion animals, including pets, can spread COVID-19 or that they might be a source of infection in the United States.
In COVID-19, 'CO' stands for 'corona,' 'VI' for 'virus,' and 'D' for disease. Formerly, this disease was referred to as "2019 novel coronavirus" or "2019-nCoV". There are many types of human coronaviruses including some that commonly cause mild upper-respiratory tract illnesses.
