Reading time: 2 min

Coronavirus is a family of viruses that normally only affects animals. Some can also be transmitted from animals to people, causing respiratory problems that generally have mild symptoms.

SARS-CoV-2 is a new type of coronavirus that can affect people. It was first detected in December 2019, in Wuhan City, Hubei Province, China. In 80% of cases it produces only mild respiratory symptoms.

The virus is known as Coronavirus SARS-CoV-2 and the disease that it causes is COVID-19.

How is Coronavirus SARS-CoV-2 transmitted?

By analogy with other infections caused by similar viruses, it seems that it is transmitted by:

Man coughing

Direct contact with respiratory secretions or droplets that are generated by the coughing or sneezing of a sick person. These secretions infect another person if they come in contact with the nose, eyes or mouth of that person. Therefore, when you cough it is important to cover your mouth with tissues or cough into the inside of your elbow, and wash your hands frequently.
