Argentina's Hantavirus Outbreak Raises Concerns Ahead of World Cup in the U.S.
Argentina is currently experiencing a significant outbreak of hantavirus, with 101 confirmed cases and 32 deaths reported since June 2025. The Andes virus strain, primarily found in Argentina and Chile, is of particular concern due to its capability for limited human-to-human transmission. This outbreak coincides with the upcoming World Cup, where thousands of Argentine fans are expected to travel to the United States to support their national team. The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) have stated that the risk of widespread transmission in the U.S. is low, as the virus requires prolonged, close contact for transmission. However, health officials are monitoring the situation closely, especially given the large crowds expected at World Cup events.
