Two more human cases of H7N9 bird flu were reported in south China's Guangxi Zhuang Autonomous Region on Monday, bringing the total number of infections to eight in the region this year.
The two patients, from the cities of Baise and Wuzhou, are in critical condition, said a statement issued by the regional health and family planning commission.
Despite the new cases, the National Health and Family Planning Commission said on Friday that the H7N9 epidemic in the country has been on the decline since emergency measures were taken.
H7N9 was first reported in humans in China in March 2013 and is most likely to strike in winter and spring.
Disease control and prevention experts said the H7N9 virus could not be transmitted from human to human.
Experts recommended people avoid contact with dead and live poultry, buy poultry products with quarantine certificates and not to trust rumors.
