CDC Reports Record-High Tick-Related ER Visits in Summer 2025, Highest Since 2017, With Children and Elderly Most at Risk

The Centers for Disease Control and Prevention (CDC) has reported that the summer of 2025 is experiencing one of the worst tick seasons in recent years, with the highest number of tick-related emergency room visits since 2017. This surge in tick bites increases the risk of contracting Lyme disease and other tick-borne illnesses, which can be difficult to detect and cause serious long-term health problems. Children and the elderly are identified as the most vulnerable groups. The CDC notes that tick bites typically rise during summer and see a smaller spike in the fall, but this year's numbers are the worst since 2019. Health officials emphasize the importance of taking precautions outdoors and recommend the use of insect repellents. Lawmakers have expressed commitment to advocating for increased research and treatment investments for Lyme disease and related conditions.
