(Bloomberg) — A mysterious lung infection in the central Chinese city of Wuhan is being monitored by the World Health Organization, which said it’s in active communication with its counterparts in China, where an investigation is underway to determine the cause.
The United Nations agency activated its incident-management system at the country, regional and global level and is standing ready to launch a broader response if it’s needed, the WHO’s regional office in Manila said in Twitter posts Saturday.
As of Friday, 44 people had been diagnosed with pneumonia, the cause of which is unknown, the Wuhan Municipal Health Commission said in a statement. That’s up from 27 three days earlier. Eleven people are in serious condition. Some of the infected worked at a fresh seafood and produce market in the city.
“China has extensive capacity to respond to public health events and is responding proactively and rapidly to the current incident in Wuhan –- isolating patients, tracing close contacts, cleaning up the market, and searching for the cause and for additional cases,” the WHO said.
Pathogen studies have ruled out more common respiratory diseases, including influenza, avian flu and adenovirus, Wuhan health authorities said. All the patients are being treated under quarantine, according to the commission.
