The Friedrich Loeffler Institute for Animal Health on the Riems, together with the Berlin Charité, was able to detect the Tula virus in a person for the first time. The virus belongs to the so-called hantaviruses.

For the first time, the tula virus, which occurs mainly in field mice, has been directly identified as the cause of a disease in humans. Molecular biological evidence of the hantavirus pathogen was provided jointly by researchers from the Friedrich Loeffler Institute (FLI) and the Charité in Berlin. The Loeffler Institute announced on Tuesday. According to the Robert Koch Institute (RKI), there has so far been very little indirect evidence of such an infection in Germany. According to the FLI, a young man in the hospital showed symptoms of acute kidney failure. Further investigations confirmed the suspicion of a hantavirus disease.

Rats and mice are possible vectors

It was not initially possible to determine which virus exactly caused the disease. A molecular analysis then showed that it was a tula virus infection. “This result now moves the field mouse and the tula virus associated with it more into the focus of hantavirus epidemiology and will require better typing of hantavirus diseases in the future,” said Rainer Ulrich, Head of the National Reference Laboratory for Hantaviruses in Animals at the FLI. Joint follow-up studies with the Julius Kühn Institute should therefore determine the spread of the tula virus in field mice and other voles more precisely. “The occurrence of human infections with the tula virus should be monitored more closely, precisely because of the mass reproductions that occur in the field mouse,” emphasized Ulrich. Hantaviruses are transmitted to humans through rodents such as rats and mice.

No human-to-human transmission

The viruses are usually inhaled, for example through contaminated dust. The viruses do not spread from person to person in Germany. According to the Robert Koch Institute (RKI), the number of cases fluctuates. Infections with the hantavirus usually cause illnesses with flu-like symptoms – high fever, headache and body aches; also nausea or vomiting. The kidneys can also be impaired, leading to acute kidney failure. Only the symptoms can be treated. There are no specific drugs or vaccinations. In Germany, hantavirus diseases in humans have so far been attributed primarily to the Puumala virus in bank voles, according to the information. This virus only occurs in the western, northwest and southern parts of Germany. The tula virus, which is closely related to the puumala virus, occurs in all parts of Germany.
