Transmission of novel coronavirus
It is currently unknown.
Further investigations are required to confirm the mode for animal-to-human and human-to-human tramission.
It is suggested that human-to-human transmission is most likely to be through direct contact with case-patients, by respiratory droplets and by fomites (contaminated objects and surfaces), as is seen with SARS-CoV and MERS-CoV infections.
What about existing cases?
Most people with confirmed novel coronavirus worked at or visited a seafood and live animal market in Wuhan. Authorities close this market from 1 January 2020.
Chinese health authorities have now implemented monitoring, control and prevention measures including contact tracing and isolation of cases. Authorities are also closing and sterilising other wet markets in the area.
