China - H5N1 Avian
Influenza Update

From Patricia Doyle, PhD

Hello Jeff - I sent this to you so that you, too, could read the double speak in this one. The 31 year old truck driver who contracted H5N1 might have contracted H5N1 by visiting a 'live' poultry market. Yes, but in another sentence they claim that there are no poultry outbreaks in the area.
Even if we are to assume that the man simply walked through the live market, then we can safely assume that the virus is MORE potent and virulent - as he had NO direct contact with poultry. Normally, we saw people infected who had PROLONGED, direct contact with poultry.
I think it obvious that the virus IS changing and we may see people who do not have prolonged, direct contact with infected birds taking ill. In future cases it may become obvious that people will: 1. contract H5N1 from brief contact with infected birds, and 2. contract H5N1 from infected people via human-to-human contact. At first, the human-to-human contact may be via close family contact but eventually it will probably be via brief social contact.

The Ministry of Health in China has confirmed the country's 19th case of human infection with the H5N1 avian influenza virus.
The patient is a 31-year-old man employed as a truck driver in Shenzhen City, Guangdong Province, near the border with Hong Kong. He developed symptoms on 3 Jun 2006 and was hospitalized on 9 Jun. He remains hospitalized, in critical condition, with severe pneumonia.
Investigation of his source of infection is under way. Preliminary reports indicate the man visited a local market where live poultry are sold on several occasions prior to symptom onset. However, health authorities have not been able to determine whether he was exposed to infected poultry at that market or elsewhere.
H5N1 infections in poultry have not been officially reported in the area.
The last (18th) confirmed case from China was an 8-year-old girl from the southwestern province of Sichuan. She developed symptoms of fever and pneumonia on 16 Apr 2006 -- see ProMED ref.(54) below. Of the 19 laboratory-confirmed cases in China reported to date, 12 have been fatal -- see WHO table at
