More than a quarter of people with Lyme disease continue to have long-term symptoms that lead to limitations in daily life even after treatment.

Every year about 1.5 million ticks bite someone in the Netherlands, especially between March and October. Most people will not get sick of that.

RIVM has investigated the so-called giant tick that was found in Odoorn in the province of Drenthe on 13 July. It is a Hyalomma marginatum female. 

One in 5 tick bites occurs in an urban area. Although most tick bites occur in the countryside, many people are bitten in urban areas as well.

For the first time, a person in the Netherlands has fallen ill after a bite from a tick carrying the tick-borne encephalitis virus (TBE virus).
