Influenza Activity Increasing in Buchanan County


In the last reporting week, the Iowa Influenza Surveillance Network indicated 130 influenza-related hospitalizations statewide, mostly among those aged 64 or greater. Several flu outbreaks have been reported in long-term care facilities, especially in central and western Iowa. The most common flu virus circulating is the influenza A(H3N2) strain, although four different strains have been identified. In years when A(H3N2) viruses dominate, the flu season tends to be more severe with more hospitalizations and deaths. Based upon CDC’s national estimates, an average of 300,000 Iowans get the flu every year and together, flu and its complication of pneumonia cause an average of 1,000 deaths yearly in Iowa.

The flu vaccine is the best defense against getting influenza; however, because some of the A(H3N2) viruses may only be partially covered in the vaccine, it’s even more important to take personal actions to help prevent the spread of illness. Remember the 3Cs: Cover your coughs and sneezes; Clean your hands frequently; and Contain germs by staying home when ill.

Anti-viral medications are an important second line of defense to treat the flu in persons at highest risk of developing more severe illness. Anti-viral medications can make flu illness shorter and reduce the risk of ending up in the hospital or dying from influenza. Antivirals work best if started within 48 hours or sooner of when flu symptoms begin.

The flu is a respiratory illness caused by viruses. The flu comes on suddenly and symptoms may include fever, headache, tiredness, cough, sore throat, nasal congestion, and body aches. Illness typically lasts two to seven days. Influenza may cause severe illness or even death in people such as the very young or very old, or those who have underlying health conditions. (The “stomach bug” which causes diarrhea and vomiting is not caused by the influenza virus but usually by norovirus; thus, the flu vaccine will not protect you against this illness.)

Contact your health care provider or the Buchanan County Public Health Department to find out where the vaccine is available in your community or use the Flu Vaccine Finder at www.flu.gov.
