1. Lyme disease
This is an inflammatory condition caused by strains of Borrelia bacteria, carried by blacklegged ticks. It’s the most common tick-related illness, and it often comes with a rash, as well as fever, nausea and muscle and joint pain. Remember: ticks may thrive in deciduous forests but populations are spreading to more urban settings.
