Iowa officials are reminding residents to take their yearly seasonal influenza vaccine.
The state Department of Public Health says people over 6 months old should get the vaccine. The State Hygienic Laboratory says the flu is circulating in Iowa.
Three cases of seasonal influenza have been identified in eastern and central Iowa in the last two months. None of the individuals were hospitalized, but they had a strain that can cause more serious illness.
Health officials urge people to cover their coughs and sneezes and to clean their hands frequently to help prevent the spread of the flu. The respiratory illness has symptoms that may include fever, headache, tiredness, cough, sore throat, nasal congestion and body aches.
