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 18 000 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.
31,6% of the ticks are carriers of an infectious disease. Every tenth tick positive for borrelia is at the same time a carrier for one more pathogen.
A tick can be a carrier of more than one infectious disease. More information about the risk of coinfection can be found here.
The incidence of infected ticks in individual years is shown in graphs
