What is COVID-19?
It is an infectious viral disease which is caused by the SARS-CoV-2 virus (COVID-19), which like any other virus tricks our immune system until it fails to work and eliminates it from the body. It causes respiratory illness in the human body and can lead to multi-organ failure as the disease progresses. The virus for this disease originated in Wuhan, China, from where it spread to other parts of the world. Till date, the virus is mutating itself creating havoc in the world. The virus is small in size and therefore can escape into the air easily. It is inhaled by a healthy person and can cause the same disease. The severity, however, can vary from person to person depending on their respective immunities. It can also occur asymptomatically in some people and can silently remain unnoticed but can be transmitted to others. The virus attacks the respiratory system of an individual and can prove fatal as well.
