IDPH says influenza now widespread in Iowa
The influenza virus is now “widespread,” the highest level of occurrence, according to the Iowa Department of Public Health (IDPH). Testing for the virus at Iowa Influenza Surveillance Network sites increased nearly 60 percent in Iowa for the week ending Dec. 27, 2014. The State Hygienic Lab has tested more than 1,000 specimens for the influenza virus, and the percentage of specimens that tested positive is increasing. IDPH has also confirmed two influenza-related deaths in children under the age of 18, and a third pediatric death is under investigation. Most of those hospitalized during the current influenza season have been adults 50 years and older.
All three strains of influenza currently circulating in Iowa -- A(H3N2), A(H1N1) and B -- are covered by this year’s vaccine. However, some of the A(H3N2) viruses appear to have “drifted,” or mutated, into a new strain. Despite the mutation, the current vaccine should still provide partial protection.
“Vaccination is still the best method of prevention,” according to Wade Aldous, director of the Disease Control Division at the State Hygienic Laboratory. “Even at this stage in the season, it’s still advisable to get the vaccine,” Aldous said.
The Iowa influenza season typically peaks in February but can last until May. Taking additional steps like staying home when ill, cleaning hands frequently and covering coughs and sneezes will also help reduce transmission of the virus.
Anyone displaying flu symptoms should immediately see their health care provider because antiviral drugs prescribed to combat the flu are most effective if administered within 48 hours of symptom onset.
