You catch Covid-19 from being around other people who have Covid-19. People who are infected breathe out tiny droplets of water containing the virus which float in the air for a while. If you breathe in the droplets, you can catch the virus. The tiny droplets containing the virus also get onto things, like a door handle. If you touch those things and then touch your face, the droplets can get into your body through your mouth, nose or eyes and you can get infected. But the virus in the droplets, whether in the air or on surfaces, die out after a while. Because of this, you can’t catch Covid-19 very easily unless you meet other people who have Covid-19 or visit places where they have been quite soon before you. Covid-19 is like a ‘small cloud of possible infection’ that follows people who are infected, not a poison that contaminates places for a long time. Indoor places are much more dangerous than outdoors because there is less moving air to blow the droplets away.
