Chance of H7N9 outbreak remains low, experts say

The risk of an outbreak of the H7N9 bird flu virus is relatively low in Guangdong, despite reports of four new cases of the virus within five days last week, health experts said on Monday.

Zhang Yonghui, director of the Guangdong Provincial Disease Control and Prevention Center, expected sporadic infections of the bird flu virus in the coming months because winter and spring are the peak periods.

"Human immunity drops, and the virus is more likely to survive and spread in low temperatures," Zhang said.
