In a split decision today, a World Health Organization (WHO) emergency committee held off on recommending a public health emergency of international concern (PHEIC) over China’s novel coronavirus (2019-nCoV) outbreak and will meet again tomorrow to reconsider after learning more about severity and transmission between humans.

China’s number of new novel coronavirus (2019-nCoV) cases nearly doubled since yesterday, approaching 600, as city officials in Wuhan—the center of the outbreak—announced aggressive measures to slow the spread of the virus, including shutting off transportation from the city.

Meanwhile, Hong Kong and Macao reported their first cases linked to the outbreak, and Thailand reported two more.

In a related development, a team based at Imperial College London today in a new estimate of 2019-nCoV activity in Wuhan said the city probably now has 4,000 symptomatic cases. The report’s 95% confidence interval ranges from 1,000 to 9,700.
