What is Covid-19?

COVID-19 is a contagious disease caused by severe acute respiratory SARS-CoV-2 The first known case was identified in Wuhan, China, in December 2019. The disease has since spread to over 200 countries and territories, resulting in a pandemic.

COVID-19 is primarily spread through respiratory droplets produced when an infected person coughs, sneezes, or talks. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
