People can catch Covid-19 from others who have the virus.
It is understood that the virus is highly infectious and moves from person to person in droplets from the nose or mouth which are spread when a person with Covid-19 coughs or exhales. In addition, the virus can survive for up to 72 hours out of the body on surfaces.
People can catch Covid-19 if they breathe in the droplets or touch infected surfaces and then touch their eyes, nose or mouth.
It is known that infected individuals who show no symptoms may still be able to pass on the virus, especially in the early stages of infection. This is described as asymptomatic spread.
