Causes Of Covid 19

Covid-19 is caused by infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus strains. It can affect your upper respiratory tract (sinuses, nose, and throat) or lower respiratory tract (windpipe and lungs). In more severe cases, the infection can cause pneumonia, severe acute respiratory syndrome, kidney failure, and even death.

The virus is transmitted mainly through the respiratory route after an infected person coughs, sneezes, sings, talks, or breathes. A new infection occurs when virus-containing particles exhaled by an infected person, either respiratory droplets or aerosols, get into the mouth, nose, or eyes of other people who are in close contact with the infected person. During human-to-human transmission, an average of 1000 infectious SARS-CoV-2 versions is thought to initiate a new infection.
