CDC(@CDCgov):In October 2024, an American man returned to Iowa after traveling to Liberia, unknowingly carrying Lassa fever. His illness showed how quickly a health threat abroad can become a threat at home. Drawing on 16 years of CDC partnership in Liberia, CDC-trained disease detectives and other global health teams partnered with CDC experts to quickly provide U.S. health officials with critical guidance to help prevent its spread—protecting Americans here at home. #CrisisToControl
