It’s tick season and public health officials are urging caution over a wider region of the country, particularly with respect to the lone star tick with a bite that can cause a red-meat allergy, or Alpha-Gal Syndrome. While the risk is still believed to be low, Maggie Astor reports in the New York Times that the spread of alpha-gal has increased in recent years due to a “warmer climate, land use changes and growing deer populations.”
Residents of the Northeast should be more concerned about blacklegged ticks and the spread of Lyme disease, Astor reports, but being aware is important still. The lone star is prevalent mainly in the South. Experts quoted in the story note the aggressive nature of lone star ticks, which “seek people out by sensing carbon dioxide … and may travel a few meters in pursuit.” Blacklegged ticks generally wait for contact.
For Stateline.org, Amanda Wartford reports an increase in emergency room visits for tick bites this year, based on data from the Centers for Disease Control and Prevention: “This year’s current figures are preliminary and subject to change, but if they hold, this year’s rate may be the highest since 2017.” More states are increasing their monitoring of tick bites, so public health officials can make more accurate predictions.
Due to warmer weather across the country, tick season is expected to last into the fall.
