The following chart depicts the percentage of ticks carrying pathogens that cause infectious diseases in humans.
Here you can see an overview of the results of more than 17 000 ticks analyzed by the team of Dr. Burýšková in Protean s.r.o. laboratory. All ticks were removed from human skin throughout the Czech Republic.
