H7N9, a bird flu strain, strikes in winter and spring. It was first reported in humans in China in March 2013.

New infections of the bird flu kept popping up in separate provinces. More than 10 cases have been reported since January begins, in Jiangxi, Shandong, Hunan, Guangdong, Guizhou, Shanghai and Macao.

Experts with the Chinese Center for Disease Control and Prevention said that China had entered high season for infection of the H7N9 virus, and the possibility of more reported cases in southern China was not being ruled out.

The public should avoid contact with dead poultry, live poultry, birds and their waste, and purchase only certified poultry products, they advised.
