Flu season 2012-2013 could be bad

The CDC influenza surveillance system indicates that seasonal flu (H3N2) has gotten off to an earlier start than usual, and the attack rates are higher than usual. Collaborating labs are reporting steadily increasing numbers of isolates. There is only one reported case of a novel virus, indicating that genetic shift has not occurred. The ILI (influenza like illness) surveillance system indicates very high activity in Texas and in some of the southeastern states. See:

for CDC’s “Fluview”. 

The actual trends have been presaged by similar increases in search term inquiries in Google Flu Trends, which has been shown to predict actual flu activity–and precede surveillance data by weeks.
