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

Some ticks can transmit infections, including Lyme disease. Not every tick is infected and most tick bites do not result in illness, but awareness helps people reduce bites, find attached ticks and remove them promptly and correctly, and recognise when symptoms need appropriate health advice. The course teaches calm, proportionate action—not fear or self-diagnosis.
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.
