On December 31, 2019, the World Health Organization (WHO) was informed of an outbreak of “pneumonia of unknown cause”, detected in Wuhan City, Hubei Province, the seventh-largest city in China with 11 million residents.
Previously referred to as 2019 novel coronavirus or 2019-nCoV, the disease originated from a new coronavirus that has not been previously identified. In a span of just a few month, the number of infected cases has grown in unprecedented rate and WHO has declared it as pandemic in March 2020.
