UK: Four people have tested positive for avian influenza

UK 25 May, 2007 Tests were performed on nine people associated with the farm, and the Health Protection Agency said in a news release that four people had tested positive for the H7N2 strain of the virus.
The Welsh health authorities said that in all but one of the four human cases the virus had spread from poultry. The other case may have been transmitted from person to person.
The only documented human case of H7 in the UK was in 1996, when a woman farmer contracted H7N7 influenza and suffered conjunctivitis.
The outbreak in Corwen is believed to have developed after 15 22-week-old Rhode Island chickens were brought to the smallholding two weeks ago, bringing the total number of birds on site to 45 chickens and two geese.
But one of the birds died the day after they were taken to the site, and by May 17, 10 birds were dead, all from the new group of chickens.
Welsh veterinary officials think the infected chickens could have been exposed to the virus on May 7 at the Chelford Market in Cheshire.
