"The World health organization (WHO) has declared COVID-19 a pandemic. COVID 19 stands for coronavirus disease 2019 and is caused by the severe acute respiratory syndrome coronavirus 2.

Coronaviruses are a large family of viruses that are common in people and many different species of animals including cats and bats. Common human coronavirus typically causes a URTI, like the common cold. Most people get infected with one or more of these viruses at some point in their lives. The human coronavirus infection typically resolves on its own with basic rest while feeling miserable.

Rarely, the coronaviruses that infect animals can evolve and become a new human coronavirus which then infect and spread between people. Important examples of these type of coronavirus include severe acute respiratory syndrome coronavirus, SARS CoV for short in 2003 and Middle East respiratory syndrome coronavirus also known as MERS."
