After being the worldwide epicenter of H1N1 swine flu this spring, H1N1 has been non-existent in NYC this fall. According to NYC health officials, there has been only one confirmed death in the city since August 30th, compared to scores in the spring. Some doctors are calling it "herd immunity". Since nearly 1 million New Yorkers were infected this spring, nearly everyone was probably exposed. Areas which previously did not see outbreaks, in the South and Midwest are now experiencing what we were months ago. Even more encouraging is that the 3 week moving average of deaths from all types of influenza is well below the rates of 2007 and 2008.
