Ticks, parasitic arachnids, are more active in the warmer seasons and live by feeding on the blood of their hosts. Tick-borne pathogens can be passed to humans by the bite of infected ticks with bacteria, viruses, or parasites. Some of the most common tick-borne diseases include tick-borne encephalitis (TBE) and borreliosis (Lyme disease).  EPA/CHRISTIAN BRUNA
