Coronavirus Outbreak 2020

Coronaviruses are species of virus belonging to the subfamily Coronavirinae in the family Coronaviridae, in the order Nidovirales. Coronaviruses are enveloped viruses with a positive-sense single-stranded RNA genome and with a nucleocapsid of helical symmetry. The genomic size of coronaviruses ranges from approximately 26 to 32 kilobases, the largest for an RNA virus.

Novel coronavirus, denoted 2019-nCoV by the WHO and also known as Wuhan coronavirus, Wuhan flu, Wuhan seafood market pneumonia virus and Wuhan pneumonia, is a positive-sense, single-stranded RNA coronavirus first reported in 2019. The virus was genomically sequenced after nucleic acid testing on a positive patient sample in a patient with pneumonia during the 2019–2020 Wuhan pneumonia outbreak.

On 20 January 2020, human-to-human transmission was confirmed in Guangdong province, China, according to Zhong Nanshan, head of the health commission team investigating the outbreak. No specific treatment for the new virus is currently available, but existing anti-virals could be repurposed. Wikipedia
