Summary

Story summary

Lyme disease affects nearly 500,000 people annually in the U.S., with 15% of Nantucket residents impacted.
Dr. Timothy Lepore, the island's only surgeon, treats many Lyme patients and may retire if disease transmission decreases.
Researchers plan to genetically engineer mice to be immune to Lyme disease, aiming to reduce their population.
Nantucket's ecosystem, altered by imported deer, has led to increased tick and mouse populations.
A small field trial will assess the ecological effects of engineered mice before wider implementation.
