A Chinese woman has been quarantined in Thailand with a mystery strain, authorities said on Monday, the first time it has been detected outside China. In all, 41 cases of pneumonia - a symptom of the disease - have been reported in the central Chinese city of Wuhan, mainly through exposure at a seafood market.
Dr. Maria Van Kerkhove, acting head of WHO's emerging diseases unit, told a Geneva news briefing that the agency had given guidance to hospitals worldwide about infection control in case of spread, including by a "super-spreading" event in a health care setting. "This is something on our radar, it is possible, we need to prepare ourselves," she said.
