Expected peak in tick bite season

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.

Remove ticks quickly, reduce your risk of Lyme disease

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.

Predicting who will experience symptoms after Lyme disease remains challenging

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.

Number of Lyme disease diagnoses remains high

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.

Fewer reports of tick bites in 2022

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.

Antibiotic use and antimicrobial resistance remain stable

Antibiotic resistance in the Netherlands remained stable in 2021 compared with the five previous years. This is evident from the 2022 annual NethMap/MARAN report.

Can healthy gut microbes protect us against antibiotic-resistant bacteria?

It is largely assumed within the scientific community that a healthy intestinal microbiome can provide resistance against the settling, growth and multiplication of antibiotic-resistant bacteria.

Ten years of Tick Radar 80,000 tick bite reports; chances of being bitten highest in Drenthe

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.

Sewage treatment workers not more likely to carry antibiotic-resistant bacteria
