The head of the University of Hong Kong's Centre for Infection, Ho Pak-leung, warned that the city should implement the strictest possible monitoring system for a mystery new viral pneumonia that infected dozens of people on the mainland, as it was highly possible that the illness was spreading from human to human. The microbiologist also warned that there could be a surge in cases during the upcoming Chinese New Year. Ho said he hoped the mainland would release more details as soon as possible about the patients infected with the disease, such as their medical history, to help experts analyse the illness and to allow for more effective preventive measures to be put in place.[50]
