Episode notes
Reported Cases Underestimate True Burden
- Official reports vastly undercount true Lyme incidence compared with modelled estimates.
- The CDC estimates ~476,000 US diagnoses and treatments per year versus ~89,000 reported cases in 2023.
Tick Life Cycle Drives Transmission Risk
- Ticks require blood meals at each life stage and feed on many wild hosts before humans.
- Only a few tick species transmit Borrelia, though over 900 tick species exist.
Remove Ticks Quickly And Correctly
- Remove attached ticks promptly using a tick remover, card, or fine-tip tweezers.
- Grip the tick close to the skin and pull straight out; don't wait for medical help.
