PITTSBURGH — The University of Pittsburgh’s Center for Vaccine Research estimates that more than one in five people in the Pittsburgh area got the swine flu last year.
The study is based on 100 anonymous blood samples taken from each of several age groups, and the results were then extrapolated for Allegheny County’s 1.2 million residents.
Based on the sample results, the scientists estimate that 261,000 county residents got the flu – or about 21.5 percent of all residents.
The study found that school-age children were the most likely to get the swine flu, about 45 percent of them did. People over 70 fared better. Only 5 percent of them got the flu.
