After weeks of low to moderate influenza levels in Iowa, the Iowa Department of Public Health (IDPH) reports statewide surveillance indicates flu activity is increasing. The most common flu virus circulating is the influenza A (H3N2) strain, although four different strains have been identified.

The flu vaccine is the best defense against getting the influenza; however, because some of the A (N3N2) 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 3 Cs: Cover your coughs and sneezes; Clean your hands frequently; and Contain germs by staying home when ill.

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.
