Four more people in East China have been confirmed to be infected with the H7N9 bird fluvirus, as a nationwide screening program has been launched for the rare but lethal strain.

Feng Zijian, director of emergency response at the Chinese Center for Disease Prevention andControl, said the country has launched a nationwide program to screen for H7N9 among patients with pneumonia, where the cause is unknown.

這一計劃得到了包括醫(yī)院在內(nèi)的公共衛(wèi)生組織監(jiān)測系統(tǒng)的支持，目的在于及時發(fā)現(xiàn)新病例。

The program, supported by surveillance systems at public health institutions including hospitals, is aimed at timely detection of new cases.
