Total number of nymphs (DON), prevalence (NIP) and estimated number of infected nymphs (DIN) per year and location (over 200 m2 and in multiple sessions). Prevalence (NIP) is calculated for each year–location combination by dividing the total number of Borrelia-positive nymphs by the total number of tested nymphs. For Vaals, the DIN and DON are based on a single transect from 2014 onwards because the other transect was not sampled after December 2013
