Since the new coronavirus was first reported in Wuhan, China in December, infectious respiratory disease COVID-19 has spread rapidly in China and neighboring countries and beyond.
The first confirmed cases of coronavirus outside of China occurred on January 20 in Japan, Thailand and South Korea. On January 21, the first case in the United States was identified in Washington State. On March 11, the World Health Organization declared the epidemic a pandemic – the first time since H1N1 in 2009.
This particular virus, officially known as SARS-CoV-2, is just the third strain of coronavirus known to cause serious symptoms in humans frequently. The other two strains are responsible for Middle East respiratory syndrome and severe acute respiratory syndrome.
