Tick Populations Expand, Bringing New Disease Concerns

Why it matters locally: West Virginia, with its significant rural and forested areas, may see an increased burden on public health resources, including those at Berkeley Medical Center and Mon Health Medical Center, as tick-borne diseases become more prevalent across the state.

Ticks are expanding their geographic range, introducing new public health concerns, according to Holly Gaff, a mathematical ecologist at Old Dominion University. While certain areas of the country have long dealt with tick populations, researchers now observe them in previously unaffected regions. The expansion of tick habitats brings with it new threats. Gaff, who studies tick ecology, noted these changes during a discussion with William Brangham concerning the parasites' broader distribution. Scientists continue to monitor these developments to understand the full scope of the expanded tick presence and the associated health implications.
