Despite a long, cold winter, ticks in Sweden can remain active, as they benefit from a snow cover that provides insulation. The first active tick was found in Kalmar County in January, with another reported in Jönköping County by March. Experts, like Dave Karlsson, suggest that the early appearance of these ticks may signal a year with a higher-than-normal tick population, increasing the risks of tick-borne diseases.

Ticks are known carriers of serious diseases such as Tick-borne Encephalitis (TBE) and Lyme disease (borreliosis). While vaccination is available for TBE, there is currently no vaccine for Lyme disease. The article highlights concerns over the potential rise in TBE cases in Sweden, referencing statistics from the Public Health Agency of Sweden that show a notable increase in reported cases in recent years. This trend raises public health alarms, urging outdoor enthusiasts to be vigilant.

The data indicates that the number of TBE cases fluctuated over the years, with 2023 showing 595 cases and projections indicating similar or increased incidence in the near future. Given the ticks' prevalence and associated risks, especially in a notable tick year, health authorities are likely to heighten their focus on both public education about ticks and the available preventive measures for the diseases they carry.
