Health authorities in Shanghai and Anhui Province, where three cases of people being infected by a new type of bird flu were detected, have increased monitoring over influenza and unexplained pneumonia cases  as the Chinese Center for Disease Control and Prevention (China CDC) assured the public that the risks of infection from the disease are "relatively low."
Â
"Currently, some regions have detected a limited number of cases and no secondary cases have arisen among those close to the patients. Judging from the limited evidence, the risk of public infection from the virus is relatively low," the China CDC said in a post on its website.
Â
Xu Jianguo, director of the Institute of Infectious Disease Prevention and Control with the China CDC, told the Global Times Monday that at this point, great attention should be paid to this new virus but there is no need to panic.
Â
The new strain of bird flu, known as H7N9, resulted in two deaths in Shanghai and a victim in Chuzhou, Anhui, is now still in critical condition.
Â
It was the first case of people being infected by this strain of the virus.Â
