Italy Activates Health Surveillance for Four KLM Passengers

The Italian Ministry of Health announced on Saturday that it has activated health surveillance for four passengers who were on a recent KLM flight and may have been exposed to hantavirus. Public-health teams have identified and notified the individuals and begun active monitoring for symptoms.

Contact tracing is under way to determine whether other travelers or crew members require follow-up. Laboratory testing is being used to evaluate any symptomatic people.

Hantaviruses are typically transmitted to humans from rodents. In rare instances certain hantaviruses can cause severe respiratory illness; authorities say the risk to the general public remains low but stress that early detection and monitoring help limit spread and ensure prompt clinical care.

Anyone on the affected flight who develops fever, shortness of breath, or other concerning symptoms should seek medical attention and inform providers about their recent travel. Regional health authorities will provide updates as investigations progress.
