"Preliminary investigations conducted by the Chinese authorities have found no clear evidence of human-to-human transmission of the novel #coronavirus (2019-nCoV) identified in #Wuhan, #China,"
Nowhere did they claim it was not transmissible from human to human. They stated chinese authorities found no clear evidence of it. Should we start basing our decisions based on what China tells us? Know of any hospitals that don't put precautions in place for a respiratory virus? Maybe only in China?
