Watch out this summer: TBE infections rising sharply

Sweden recorded 213 TBE infections by 20 July, almost twice the 111 reported at the same point in 2024, according to figures reported by SVT and TT.

The 2025 comparison was 138 cases by the same date. Sweden ultimately recorded 504 cases last year, 31 per cent more than in 2024. The Public Health Agency says incidence has risen by an average of six per cent a year since 2016.

TBE is a virus transmitted mainly through tick bites. Most infected people do not become ill, but some develop fever, headaches and muscle pain. A smaller group develops inflammation of the brain or its surrounding membranes, which can require hospital care and cause lasting problems.

The agency recommends vaccination for adults and children aged three or older who risk tick bites in its highest-risk areas. People with weakened immune systems have wider recommendations. Vaccination is usually self-funded, although regional subsidies vary.

Ticks favour moist, dense vegetation and are most active during the warmer months. The agency advises checking skin and clothing regularly, including the whole body after time in tick habitats. Contact 1177 if a bite is followed by fever, headache or feeling unwell.
