"Shouldn’t we all be dead by now?" is the first question that Kent Sepkowitz, card-carrying hospital epidemiologist, asks in his latest article in Newsweek. He goes on to ponder why it's almost February and there's so little influenza activity and suggests that nothing we have done to prepare has made any difference including influenza vaccination and alcohol hand rub . He hints that perhaps La Nina or climate could be a possibility.
He concludes by saying: "In fact, what we are seeing here is the dark secret of medicine and public health: the fact that we usually have no clue why something, good or bad, is happening...(and) should accept that we are mere spectators to an inscrutable alliance of virus, animal, and climate, a longstanding collaboration that we cannot, as yet, influence — though getting that flu shot might help."
