Coronavirus is a family of virus that leads to illness or aggravation of respiratory problems. It can be transmitted between animals and people, a phenomenon called spillover. COVID-19, a particular strain of this family of virus, has been massively found in humans. Official sources have reported that the virus spread from a group of people with pneumonia who were connected to a seafood and live animal market in Wuhan, China. The virus has since then spread between people in China and to other countries all over the world.
