Sharp increase in TBE cases in Sweden
The number of people infected with the TBE virus in Sweden has increased significantly this year. So far, 213 cases have been reported, which is a substantial increase compared to previous years.
To put the figures into perspective, one can compare them with the same period in recent years. In 2024, 111 cases were reported, and in 2025, the figure was 138 cases at the same time. The current increase is therefore clear and is reflected in the statistics.
TBE, or tick-borne encephalitis, is a viral disease spread through tick bites. The virus can cause inflammation of the brain or the membranes surrounding the brain, which can lead to serious health problems. Authorities therefore often recommend vaccination for people who spend a lot of time in nature in high-risk areas.
It is still unclear exactly what the sharp increase is due to, but experts emphasize the importance of being vigilant about ticks when out in forests and fields. Wearing full-coverage clothing and checking the skin after spending time in nature are fundamental protective measures.
The Public Health Agency of Sweden continues to monitor the development closely. For those who live or spend time in areas where TBE is common, the advice is to review their vaccination protection to reduce the risk of contracting the disease.
