Tick-Borne Diseases Surge Nationwide Driven by Climate Change

Tick-borne diseases are increasing across various U.S. regions, driven largely by climate change which extends tick seasons and expands their habitats. In California, cases of anaplasmosis in dogs have nearly tripled over the past five years, signaling growing public health risks as these ticks also transmit Lyme disease. South Carolina sees rising tick-borne illnesses such as Rocky Mountain Spotted Fever, Lyme disease, and Southern Tick-Associated Rash Illness, with experts emphasizing preventive measures. Oklahoma reports its highest emergency room visits for tick bites since 2019, attributed to milder winters and wetter springs that support tick survival, urging public vigilance in personal and pet tick prevention. In New England, notably Maine and Massachusetts, babesiosis cases have surged dramatically, with the disease season extending from just over two months to nearly year-round, highlighting the impact of climate warming on disease prevalence. Experts across these regions stress the importance of protective actions like wearing appropriate clothing, using repellents, and conducting thorough tick checks to combat the rising threat of tick-borne diseases.
