How is COVID-19 Coronavirus transmitted?

The disease is spread by droplets (invisible secretions from sneezing or coughing). It is therefore considered that close contact with a sick person is necessary to transmit the disease: same place of life, direct contact within a meter during a cough, sneeze or a discussion in the absence of protective measures. One of the other preferred vectors for the transmission of the virus is contact with unwashed hands.
This is why barrier gestures and social distancing measures are essential to protect oneself from the disease.
