Suspected hantavirus case in Romania – epidemiological investigation under way in Arad and Bihor

Health authorities in Romania have launched an epidemiological investigation after a patient admitted to a psychiatric unit in Bihor County developed symptoms consistent with a hantavirus infection. The case has raised concern among specialists, as it is the first of its kind reported in the region.

The patient in question had been admitted to Ștei Hospital since 2023 and recently presented with clinical manifestations typical of hantavirus infection. The National Institute of Public Health (Institutul Național de Sănătate Publică) confirmed that the situation is being thoroughly investigated in order to establish a definitive diagnosis and identify the source of contamination.

The epidemiological investigation is being conducted simultaneously across two counties — Arad and Bihor — with health authorities working to trace the route of infection and identify any individuals who may have been exposed to risk. This process involves assessing hygiene conditions in medical facilities and identifying all of the patient's direct contacts.

Hantavirus is a viral infection transmitted primarily through contact with rodents or through inhalation of contaminated particles from environments in which they live. Symptoms can include fever, muscle pain, respiratory problems and, in severe cases, kidney failure.

For elderly people and those with chronic conditions, this infection can pose heightened risks, which is why authorities are urging increased vigilance and strict adherence to hygiene measures in care facilities.
