RIVM and Wageningen University researchers expect the tick bite season to reach its peak in the next few weeks. The peak will coincide with the start of the summer holidays.

Ticks are active again, as shown by the increase in tick bite reports on Tekenradar.nl. Quick action is important: the faster you remove a tick after it bites you, the lower your risk of contracting Lyme disease.

Today, RIVM will publish the new version of the Dutch Food Composition Database (Nederlands Voedingsstoffenbestand, NEVO). This contains information on the composition of more than 2,300 foods.

Each year, approximately 27,000 people are diagnosed with Lyme disease. For most, the symptoms disappear after treatment with antibiotics. Unfortunately, 25% of those treated have chronic symptoms, such as fatigue, concentration disorders or pain.

In 2022, the number of enteric infections – which mainly cause gastrointestinal symptoms – was higher than it was in the previous two years. However, the total number of infections was still lower than before the coronavirus pandemic.

In 2021, the number of Lyme disease diagnoses with a red ring or rash– known as an erythema migrans, or EM – remained as high as in the previous survey in 2017. GPs diagnosed 25,600 patients with a red ring or rash caused by the Lyme bacteria.

In 2022, the reported number of tick bites in the Netherlands fell by a third compared to previous years. In order to find a satisfactory explanation for such differences, researchers at WUR and RIVM have initiated a large-scale study via Tekenradar.nl. This will give them more insights into the 1.5 million tick bites in the Netherlands every year.

After recording 80,000 tick bites in 10 years via Tekenradar.nl, we now know that you are most likely to be bitten by a tick in Drenthe. Quickly removing the tick halves the chance of contracting Lyme disease.
