What is a coronavirus?
Coronaviruses are a type of virus known for causing disease in humans and are common across the world. COVID-19 is a disease causes by a new strain of coronavirus first identified in Wuhan City (China) in December 2019.
The incubation period of COVID-19 is between 2 and 14 days. This means that if a person remains well 14 days after contact with someone with a confirmed case of COVID-19, it is unlikely that they have been infected.

Droplets produced when an infected person coughs or sneezes (termed respiratory secretions) containing the virus are most likely to be the most important means of transmission.
There are two routes by which people could become infected:
