Ticks can spread diseases when they are infected with certain types of bacteria, viruses, or parasites. Transmission to humans occurs through the bite of an infected tick. People who spend time outdoors in tick-infested environments are at an increased risk of becoming infected. Ticks are most active in warmer months (April-September), though tickborne diseases have been reported during every month of the year.
