Seasonal Influenza Vaccination Efforts
Seasonal influenza season typically begins in Iowa in late November or early December, peaking in January or February and ending in March or April.
While H1N1 disease is widespread right now, seasonal influenza disease has not yet been seen in the state, however, cases of seasonal influenza B and seasonal A(H3N2) have been reported by states in the Midwest region. More seasonal flu vaccine has been made this year than last year.
Seasonal influenza vaccine supply continues to arrive in the state with additional vaccine expected in November and December (The H1N1 vaccine does not provide protection from seasonal flu, or vice versa). It is anticipated there will be enough seasonal influenza vaccine for anyone wishing to be vaccinated.

Influenza activity has been declining; the highest levels of activity in schools and outpatient settings were reported approximately two weeks ago. However, H1N1 activity, including hospitalizations and deaths, remains far above baseline levels.

Weather’s Effect on Illness
As we go into the winter, not only do temperatures decrease but so does humidity. The loss of moisture in the air causes the mucosal membrane barrier to become less effective. This may be one of the reasons respiratory viruses and other diseases such as meningococcal meningitis cause more illness at this time of year. Studies have also shown that once someone has influenza or another severe respiratory virus, secondary infections, both bacterial and viral are more common.
Be sure you are up to date on not only the seasonal flu vaccine (and the H1N1 vaccine if recommended), but pneumococcal, meningococcal, Hib, and any other bacterial vaccines as recommended. Meningococcal vaccine is especially important for certain populations such as students living in dormitories and laboratorians who work with this organism.
