The infectious disease caused by the most recently discovered coronavirus is known as COVID-19. This new virus and disease were unknown before the outbreak began in China (Wuhan) in December 2019.
The incubation period (time between catching the virus or exposure to a virus and the appearance of the first symptoms of the disease) for COVID-19 range from 1-14 days, most commonly around five days. According to findings from new studies, an infected person may be contagious even before they start to experience the first symptoms. The reproduction number (R0) of the virus is estimated to be 2–3. This means that one infected person can infect 2 to 3 others.
