Hachoo the Flu?

By Corinna Schrankel, MD, FAAP

Yes, respiratory season is here. Typically the transition from late summer viruses to fall and winter respiratory illnesses occurs just when the kids are back in school and the germs start circulating.

Head colds, or upper respiratory illnesses (URIs) are just that. Symptoms include bothersome sneezing/congestion, cough from postnasal drip, a scratchy throat, and maybe a low-grade fever. But typically URIs are self-limited viral infections, gone within a few days. They are usually not associated with bacterial complications like sinus infection, strep, or pneumonia and therefore do not need antibiotic coverage

The flu, or influenza, on the other hand is a serious viral infection affecting the lower respiratory tract. It has a high incidence of pneumonia and secondary serious bacterial infections are very common, and sometimes need hospitalization, or in some cases, even lead to death. These complications are primarily the reason to vaccinate against influenza.

Every season the influenza virus changes just a little bit, or we have a totally new strain like the 2009 swine flu (H1N1), so we have to vaccinate every year to protect against that season's strain.

There are very few reasons NOT to vaccinate, one being severely allergic to eggs (not just “I don't like eggs”), or if you are sick with a fever. Your doctor or provider will be able to tell you which flu vaccine is better for you, the shot (killed/inactivated version) or the nose spray flumist (live-attenuated).

This year both the seasonal H3N2 and the H1N1 (swine flu) vaccines are included in one vaccine. All children less than nine years of age who have never had either the seasonal influenza vaccine or last year's H1N1 influenza vaccine should have two doses, given one month apart, in order to boost their immune response.

First defense measures to protect against respiratory illnesses are important. They include washing hands frequently, limiting contact with sick persons, and avoiding large crowds during the peak of respiratory season. Anti-infective gels and wipes are a must if you are on the go, and many public places offer hand sanitizers now too.

So, ask questions, call for advice, get informed and make the right choices when it comes to your child's health. Don't hesitate; vaccinate.
