As temperatures have warmed up, we are seeing that the "biting" season for ticks is already underway!
Until last year, we had seen increasing reports of Lyme disease cases for several years. In 2023, the number of locally reported RCAHD Lyme disease cases (91 cases) increased more than 50% over 2022 (58 cases).*
We are cautiously optimistic, however, that the drop in local cases of Lyme disease reported in 2024 (34 cases) will continue as people continue to take steps to prevent tick-borne illnesses.
In recent years, we have also seen increases in acquired red meat allergies, sometimes referred to as "alpha-gal syndrome," also caused by ticks. In addition to Lyme disease and alpha-gal, RCAHD routinely receives reports of other tick-borne diseases such as Rocky Mountain spotted fever and ehrlichiosis.
*The Lyme disease case definition changed in 2022, resulting in a reclassification of cases that may not have been previously counted.
Before going outside:
- Apply EPA-registered insect repellent
- Treat clothes and gear with products containing 0.5% permethrin
- Stick to the path and avoid brushy areas
- Prevent ticks on pets
The most important protection strategies are those that prevent you from being bitten in the first place. The best protection is to use an insect repellant that protects against both ticks and mosquitoes, such as those with a concentration of 20-50% DEET. Follow the product label directions for safe use on your skin and clothes. Although natural substances such as eucalyptus or lemon oil have repellant qualities, they may not be as effective as DEET.
Pre-treat your shoes and clothes with permethrin spray to provide a long-lasting repellant barrier. Also, tuck your pants into your socks when you are outdoors, and remember to protect your pets: medicated collars, and oral or topical products formulated for pets can be very effective.
After outdoor activity, inspect yourself and your children, clothing, and gear for ticks. The running water of a shower can also wash away ticks before they attach.
