The risk of "limited human-to-human transmission"

The situation of infection among healthcare workers is an indicator of the transmissibility of a virus. Hong Kong people still have fresh memories of the widespread infection of SARS among healthcare workers when the outbreak began in the city's hospitals. By comparison, the Wuhan pneumonia caused by the novel coronavirus has not infected any healthcare workers so far. Drosten thinks it shows that the virus is not easily transmissible from human to human. The main syndromes of the disease are fever and pneumonia. The upper respiratory tract is spared. The absence of syndromes like sneezing or a runny nose naturally means that it is harder to spread the disease.
