map. The map is based on lab confirmed cases. But we’re not testing everybody anymore. So the maps created when we were testing everyone are a good indication of the proportion of people with H1N1. Maps created since the testing change only indicate the proportion of people who have very serious cases of H1N1. Apples and oranges.

Pretty up to date as of this posting. Map I’m not sure I get the significance of this since most people are no longer getting tested. “Doctors are asked to only submit patients’ specimens for testing where lab results are required for clinical management of hospitalized cases of influenza-like illness or where patients are at high risk for complications from influenza. These include people who are immunocompromised, pregnant, under the age of 2 years or over age 65. ” Source. So what does this map really show?
What’s probably more interesting is this graph because it shows if things are getting worse on not by focusing on a tested population.
Figure from the Ontario influenza bulletin. Keep in mind these data come from IPHIS, and there’s likely a bit of a lag in getting the test results.
