Ticks Spread Across Sweden Linked to Climate Change

The spread of ticks across Sweden is linked to climate change, raising public health concerns.

Key Points

  • • Ticks have now spread across all of Sweden.
  • • Helena Partapuoli found a tick on her dog in Kiruna.
  • • SVA urges the public to submit ticks for research.
  • • The increase in ticks is attributed to climate change.

Ticks have now spread across all of Sweden, raising public health concerns as climate change impacts their distribution. Helena Partapuoli from Kiruna reported finding a tick on her dog, marking a notable observation as the days of northern regions being tick-free appear to be coming to an end. According to the Swedish National Veterinary Institute (SVA), the ticks identified in northern areas are primarily Ixodes ricinus and Ixodes persulcatus, though their presence is still relatively low compared to central and southern Sweden.

SVA researcher Anna Omazic remarked on the changing dynamics, explaining that while northern municipalities such as Norrbotten and Västerbotten are currently not classified as risk areas for tick-borne diseases, increased awareness is crucial. She advised the public to check themselves and their pets after spending time outdoors. Omazic further connected the rising incidence of ticks to climate change, mentioning that warmer winters and longer growing seasons allow these pests to thrive in previously uninhabitable areas.

Partapuoli, now vigilant, has altered her routine to inspect her dog daily for ticks. Although there are no current vaccination recommendations related to tick-borne diseases in the northern regions, the SVA encourages the community to send in ticks for research purposes, highlighting the importance of citizen involvement in tracking this growing health risk.
