The Alongshan virus was discovered in China only five years ago. Now researchers at the University of Zurich have found the novel virus for the first time in Swiss ticks. It appears to be at least as widespread as the tickborne encephalitis virus and causes similar symptoms. The UZH team is working on a diagnostic test to assess the epidemiological situation.

Ticks can transmit many different pathogens such as viruses, bacteria, and parasites. Of particular concern are the tickborne encephalitis virus (TBEV), which can cause inflammation of the brain and of the linings of the brain and spinal cord, and bacteria leading to the infectious Lyme disease (borreliosis). The list of pathogens transmitted by ticks continues to increase, also in Switzerland: researchers from the Institute of Virology at the University of Zurich (UZH) have now detected the Alongshan virus (ALSV) for the first time in ticks in Switzerland.
