Covid 19 is a highly contagious infectious disease caused by a novel Corona virus called Severe Acute Respiratory Syndrome-Corona virus 2 (SARS Cov 2). It spreads 2 to 4 times faster than regular flu and has a long incubation period of 14 days.

It was first reported from Wuhan city in the Hubei province of China in December 2019 and was the cause of an outbreak of pneumonia of unknown origin. It was declared as a pandemic by WHO on March 11 2020.

It is spread primarily through respiratory droplets when an infected person talks, sneezes or coughs. Airborne spreading has not been reported based on all the available evidence. However, people can get infected by touching contaminated surfaces or objects and then touching their eyes, nose or mouth.

Some people become infected but do not develop any symptoms at all. However, they can be carriers of the virus. Around 1 out of every 6 infected people can develop serious complications like pneumonia and breathing difficulties.
