H1N1 flu strain may be 'on its last legs' in South Dakota
Jon Walker ? Argus Leader ? February 10, 2010
South Dakota may have achieved herd immunity against H1N1 flu.
About 250,000 state residents have received the vaccine and another 150,000 have had the illness. That totals about half the population, perhaps enough to keep the virus from spreading.
?Once you vaccinate enough people it does interrupt the spread greatly,? said Dr. Aris Assimacopoulos, infection control director at Avera McKennan Hospital in Sioux Falls.
Specialists expected a third wave of H1N1 by this spring but waver now on that prediction. ?It?s probably correct to say this particular strain is on its last legs, but the concern will be whether you begin seeing a mutated form,? Assimacopoulos said.
