Bornavirus: vigilance in demand! First dead in Bavaria alerts experts

The Bornavirus, also known as Borna Disease Virus 1 (Bodv-1), was long considered animal disease that affects sheep and horses. But since 2018, scientists have known that the virus can also lead to severe brain inflammation in humans. Current reports and medical examinations have shown that the disease that is considered to be fatal can no longer be dismissed as a pure animal disease. This is confirmed by a recently reported death and two new infections in Bavaria.

On June 2, 2025, it was announced that two people in Pfaffenhofen, Bavaria, are infected with Bornavirus. One of the infected people has already died while the other is in medical treatment. According to estimates by the Robert Koch Institute (RKI), around five to ten acute illnesses occur annually in Germany. Most human infections are registered in rural areas, especially in Bavaria.

transmission and danger

The virus is transferred to humans through contact with Feldspitz mice that act as a natural host. As a rule, these small animals do not show symptoms, but they output the virus over urine, feces and saliva. In Central Europe, the endemic areas for the Bornavirus can be found especially in Bavaria, Saxony-Anhalt, Brandenburg and Thuringia. An exact type of transmission has not yet been clearly clarified; Possible ways are the contact with infected animals, inhaling contaminated dust or eating contaminated food.

The disease was not liable to report until 2020; Since then, the RKI has registered up to six acute cases a year. Symptoms of infection are extremely serious and at the beginning contain headache, fever and general feeling of illness, followed by neurological problems such as language and gait disorders. As a rule, the disease leads to severe consequential damage or death in a short time. So far, all patients have died after a single case after incorrect diagnosis.

prevention measures

Since there is no specific therapy or vaccination against the BornaVirus so far, preventive measures are of the utmost importance. The RKI recommends not having direct contact with Feldspitz mice and their excretions, since the risk of infection is highest. In addition, dead mice should never be touched with bare hands and always used when cleaning the cat.

The health authorities advise you to identify and eliminate food sources of pointed mice in the garden or house. The touch of Igeln, whose role as a carrier is still unclear, should also take place with caution. Despite the low infection rate, the Bornavirus remains a serious health risk, especially in rural areas in Germany. In view of the alarming news, it is important to be aware of the potential dangers and take appropriate protective measures.
