Module 1 of 8 · 8–12 minutes
Recognise ticks and understand scale

Tick awareness can reduce avoidable bites and delay in correct removal, while helping learners recognise when adult or clinical advice is appropriate. Some ticks transmit infections, including Lyme disease, but not every tick is infected and most bites do not cause illness. Teaching must balance meaningful prevention with calm, evidence-based risk communication.
Ticks are arachnids, not insects. Larvae have six legs; nymphs and adults have eight. Species, stage, sex and feeding state change appearance. Ticks can be extremely small, and a photograph cannot show whether one carries infection.
