The first patients hospitalised for infection with the novel coronavirus (2019-nCoV) had viral pneumonia, with most initial symptoms being fever, dry cough and malaise, according to one of the first publications on the outbreak.

Another early report notes that some infected people in the community may be asymptomatic but shedding virus, while others are described as “cryptic cases of walking pneumonia”.
