US may have 1 million pandemic flu cases
A surveillance expert from the CDC said yesterday at the agency's immunization group meeting in Atlanta that the true number of pandemic H1N1 cases in the United States could be as many as 1 million, the Associated Press (AP) reported today. Lyn Finelli said the projection was based on mathematical modeling and surveys from health officials. She told the Advisory Committee on Immunization Practices (ACIP) that 6% or more of the population from some urban areas could be infected with the virus.

Novel flu edging out seasonal strains in Australian state
The pandemic H1N1 strain is dominating seasonal flu strains in Victoria, according to a report from the Victoria Infectious Diseases Reference Laboratory (VIDRL) that covered last week. Of 138 influenza A samples tested, 60 were novel H1N1, 3 were H3N2, and 2 were seasonal H1N1. Victoria is the state with the most confirmed novel flu cases, 1,560 of Australia's 3,519. Experts predicted that the new flu strain might push out seasonal strains as the southern hemisphere's flu season progresses.

Part of UK moves away from pandemic flu containment
Health officials in England said pandemic flu response in two parts of the country will shift from a containment to a management strategy, the London Daily Mail reported today. The change, which affects London and West Midlands, means that schools will no longer close and that antiviral medication will no longer be given to close contacts of flu patients, only those who have illness symptoms. Also, most illnesses will be diagnosed clinically rather than through lab testing.

Two workers were sick at Argentine pig farm
Animal health officials from Argentina said yesterday in a report to the World Organization for Animal Health (OIE) that two workers at a pig farm where the animals tested positive for novel H1N1 were sick between Jun 7 and 9, but did not seek medical care or undergo testing. The report said pigs started getting sick on Jun 15. The virus sickened 30% of the 5,586 pigs, but none have died. The facility has its own restocking system, and no pigs have entered from outside the farm since July 2008.
