Everything starts with December 31, 2019, when the World Health Organization (WHO) was informed of an outbreak of “pneumonia of unknown cause” detected in Wuhan City, Hubei Province, China – the seventh-largest city in China with 11 million residents.
The first reported infected individuals, some of whom showed symptoms as early as December 8, were discovered to be among stallholders from the Wuhan South China Seafood Market. Subsequently, the wet market was closed on Jan 1. The virus causing the outbreak was quickly determined to be a novel coronavirus. On January 10, gene sequencing further determined it to be the new Wuhan coronavirus, namely 2019-nCoV, a beta coronavirus, related to the Middle Eastern Respiratory Syndrome virus (MERS-CoV) and the Severe Acute Respiratory Syndrome virus (SARS-CoV). However, the mortality and transmissibility of 2019-nCoV are still unknown, and likely to vary from those of the prior referenced coronaviruses.
Infected travelers (primarily air) are known to be responsible for introductions of the virus outside Wuhan. On Jan 13 Thailand reported the first international case outside China, while the first cases within China, but outside of Wuhan were reported on January 19, in Guangdong and Beijing. On January 20, China’s National Health Commission (NHC) confirmed that the coronavirus can be transmitted between humans. On the same day human infections with 2019-nCoV had also been confirmed in Japan and South Korea, and the following day cases in the U.S. and Taiwan were detected in travelers returning from Wuhan. On January 21 multiple provinces in China were also reporting new cases and infection was confirmed in 15 healthcare workers, with six fatalities reported. Additional travel cases have now been confirmed in Hong Kong, Macau, Singapore and Vietnam. On Jan 22, a WHO emergency committee convened to discuss whether the outbreak should be classified as a public health emergency of international concern (PHEIC) under International Health Regulations, but were initially undecided due to lack of information, before deciding against the declaration.
+ 14K deaths confirmed + ~100k total recovered cases confirmed.

All of the 213 deaths reported have been in China, 182 were from Hubei province, two from Henan province, one from Beijing, one from Hainan province, one from Heilongjiang province, one from Hebei province, one from Shanghai, and one from Sichuan province.
In response to this ongoing public health emergency, The Center for Systems Science and Engineering (CSSE) at JHU has developed an online dashboard (static snapshot shown upper) in order to visualize and track the reported cases on a daily timescale; the complete set of data is downloadable as a google sheet. The case data visualized is collected from various sources, including WHO, U.S. CDC, ECDC China CDC (CCDC), NHC and DXY. DXY is a Chinese website that aggregates NHC and local CCDC situation reports in near real-time, providing more current regional case estimates than the national level reporting organizations are capable of, and is thus used for all the mainland China cases reported in our dashboard (confirmed, suspected, recovered, deaths). U.S. cases (confirmed, suspected, recovered, deaths) are taken from the U.S. CDC, and all other countries (suspected and confirmed) case data is taken from the corresponding regional health departments. The dashboard is intended to provide the public with an understanding of the outbreak situation as it unfolds, with transparent data sources.
