PHOENIX, AZ — State health officials say that the worst of H1N1
passed last flu season, according to The Herald.
"We expect H1N1
to be back again this year because that''s what happens when we have pandemics," said Karen Lewis, the medical director for the Arizona Immunization Program
, part of the state Department of Health Services
"But it tends to not have quite the severe impact because fewer total people are infected," Lewis added.
What impact H1N1
will have this year is difficult to predict: Individual immunity, immunizations from last year and the mutating nature of influenza make it difficult to forecast, said a spokesperson for the Maricopa County Department of Public Health
Despite this, health officials remain optimistic that H1N1
will not be as virulent as it was the previous year, the article noted.
