The Coronavirus Disease, or Covd-19, was discovered in Wuhan, China in 2019. It is caused by a virus (SARS-CoV-2).

A virus is a tiny living thing that causes sickness by gaining access to host cells and then takes them over to multiply itself.

Covid-19 targets the cells of the respiratory or breathing system. It can affect your lungs and airways. Most people with the COVID-19 virus will experience mild to moderate respiratory (breathing) illness and recover without needing special treatment.

COVID-19 is called a pandemic because it is an infectious disease affecting different countries affecting and a large number of people.
