Abstract
Purpose
There are more than 500,000 employees in Germany alone who are at risk of being bitten by a tick at their workplace and thus also at risk of being infected with Borrelia burgdorferi s.l. or the tick-borne meningoencephalitis virus. So far, there are only a small number of studies on the risk of tick bites in Central Europe, in particular, for military personnel during relevant training activities.
Methods
During a total of 36 months of training in 2008/2009 and from 2012 to 2014, the number of tick bites and any resulting diseases of 1156 recruits under comparable conditions of exposure and prevention were documented based on their medical records. The incidence of tick bites was calculated with each recruit’s individual exposure time for field training.
Results
There were a total of 66 tick bites during an exposure time of 317,059 h of field training (0.21 tick bites per 1000 h of training). The risk of tick bites was found to have a seasonal dependency. In 6 out of the 66 cases in which someone was bitten, the patients consulted a physician for a follow-up examination, and in one of these cases the bite resulted in an infection requiring treatment.
Conclusions
It turns out that there is a rather low but relevant risk of being exposed to tick bites for military personnel during their field training. Under the given study conditions, months with a high risk of tick bites can be distinguished from months with a low risk of tick bites, which is of vital importance, in particular, for guidance and prevention.
