Health officials are investigating the death of an Iowa resident possibly resulting from Lassa fever, a viral infection rarely seen in the U.S. The individual likely contracted the virus while traveling in West Africa. The risk of transmission in Iowa is low, with the virus spreading primarily through infected rats. Symptoms include fever, fatigue, and in severe cases, bleeding, and breathing difficulties. The CDC is monitoring close contacts of the patient for 21 days. Travelers to West Africa should take precautions to avoid contact with rats. Healthcare providers treating Lassa fever patients should follow strict infection control measures to prevent the spread of the virus.
