Avian influenza update on situation in China 6

The Chinese Ministry of Health has confirmed an additional case of someone on the China mainland, being infected with the H5N1 strain of the avian influenza virus. A 41 year old woman from the south east province of Fujian developed the symptoms associated with fever followed by pneumonia on December 6, 2005. She was then admitted to the hospital on December 8, 2005.The patient died on December the 21st.

On December 13, the initial laboratory tests on samples from the patient tested negative for H5N1. However, further tests on December 23, including PCR tests carried out at the Chinese Center for Disease Control in Beijing, showed positive results.

Persons who were in close contact with the infected women have so far showed no signs of the virus.

Authorities from the Agricultural department have so far not been able to confirm the presence of the H5 virus subtype in poultry in the vicinity of the patient’s residence or place of work. Investigators have not been able to confirm any direct contact between the patient and poultry prior to the onset of illness. The investigation, however, is continuing and answers to these and other questions are still being sought.

This is China’s seventh laboratory-confirmed human case. Of these cases, three have been fatal (including this latest case). To date, China has reported human cases in six provinces and regions: Hunan, Anhui, Guangxi, Liaoning, Jiangxi and Fujian.
