Guangdong province has warned of a possible outbreak of H7N9 bird flu in the coming months after a new case was reported on Wednesday.

Zhang Yonghui, director of Guangdong provincial center of disease control, warned that Guangdong has entered a peak period for flu cases.

Cities in the Pearl River Delta, which borders Hong Kong and Macao, have higher risks of an outbreak of H7N9 in winter and spring, "the traditionally peak period for flu", Zhang said.
