China on Sunday [10 Feb 2013] reported 2 human cases of the highly pathogenic avian influenza H5N1 virus in the south western city of Guiyang, the Ministry of Health announced. A 21 year old woman and a 31 year old man, who developed symptoms on 2 Feb 2013 and 3 Feb 2013 respectively, tested positive for the H5N1 virus on Sunday [10 Feb 2013], the Ministry said, citing local health authorities.
“They are in critical condition and medical workers are carrying out emergency treatment,” the ministry said in a statement. “No epidemiological connections have been found between the 2 cases.”
An investigation did not find the 2 had contacts with fowl before they fell ill, it said. People who had close contacts with the 2 patients have been put under medical observation, but none of them has been found ill so far.
The human highly pathogenic avian influenza is an acute respiratory infectious disease mainly caused by the deadly H5N1 virus. The main symptoms include high fever and pneumonia. The human cases of bird flu are mainly transmitted from poultry to humans and there are no reported outbreaks of sustained human-to-human transmission.
