First Case of Tick-Borne Disease Confirmed in Norway This Year
Oslo, Norway – September 4, 2025 – Norway’s National Institute of Public Health (FHI) has confirmed the first case of tick-borne encephalitis (TBE) in a Norwegian resident this year. The case underscores the growing importance of preventative measures as tick populations expand and activity increases across the country.
The confirmation comes as health officials monitor rising tick numbers, with over 900 tick species identified globally and approximately ten detected within Norway. While several tick species exist in Norway – including the forest tick, hedgehog tick, sand tick, and mouse tick – the forest tick is of particular concern due to its role in transmitting infections to humans. This initial case serves as a critical reminder for individuals spending time outdoors to take precautions against tick bites.
“We have several ticks in Norway. The forest tick is the most crucial thing we follow when it comes to spread of infection to humans,” stated Steinert at FHI. “Of those established in Norway, we find, among other things, forest ticks, hedgehog ticks, sand swells and mouse ticks.”
The FHI recommends preventative measures such as wearing long sleeves and pants, using insect repellent, and performing thorough tick checks after spending time in wooded or grassy areas. Early detection and removal of ticks are crucial in minimizing the risk of infection.
