Are you going on holiday soon? OHPact needs your help! Help us by working with us to map mosquitoes, ticks and the diseases they can transmit.

Anyone aged 18 and over who is going on holiday for seven days or more in the Netherlands, Europe or the Dutch Caribbean this year can participate. During your holiday you answer a few questions via an app. In addition, we ask you to donate a few drops of blood once via a finger prick.
