Shenzhen has reported its first, and Guangdong’s sixth, case of a human infected with the H7N9 strain of bird flu, The Standard reports. The 38 year-old man surnamed Ou is in a critical condition.

Ou went to a clinic in Longgang District’s Nanling Village on Dec. 9 with a fever and a cough. On December 17, a sample from the patient tested positive for the H7N9 avian influenza virus at the Shenzhen Disease Control and Prevention Centre. The results were confirmed by provincial authorities one day later. He is now at Shenzhen No 3 People’s Hospital.

On Wednesday, Yangjiang was found to have its second and Guangdong’s fifth case. The 62 year-old male patient is also in a critical condition.

Guangdong appeared to have been out of the woods when the province’s first sufferer was discharged from hospital in early September. However, the province’s approach to containing the virus has been far from exemplary.
