The period between the time of infection and the time symptoms manifest is called the incubation period.

Transmission of Coronavirus

COVID-19 can be spread from one person to another through respiratory droplets from the coughs and sneezes of infected persons. So just contact with the respiratory droplets of an infected person would get you infected too.

The virus is said to be active even on surfaces of things around us. This means it takes some time for the virus on a surface to die off. This leaves us prone to being infected when we also come in contact with a surface that still has an active virus. Different surfaces have shown different periods for the virus to die off.

The virus is dead on copper after 4 hours, 24 hours on cardboard, 72 hours on stainless steel and 72 hours on plastic. This would make us more careful with everything around us. This disease has also not shown any attack on children and pregnant women up until now.
