We are concentrating on the 2019 nCoV outbreak, but we should not forget that other epizootic diseases, such as avian influenza, could again spur an outbreak in humans. Novel disease outbreaks are not necessarily sequential. It would be a disaster if public health officials had to battle an influenza epidemic along with a coronavirus epidemic.
