Most tick bites are harmless. But some ticks carry more serious diseases such as Lyme disease, babesiosis, and Rocky Mountain spotted fever. Some ticks, most commonly the lone star tick found in South, East, and Central states, can cause Alpha-gal syndrome. This results in an allergic reaction to red meat and other things. These diseases can spread to people. Lyme disease is the biggest concern. It's carried by blacklegged ticks. In the eastern and midwestern United States, it is often called the deer tick, and on the West Coast, it is call the blacklegged tick. Many public health departments can look at a tick and know if it's the type that causes Lyme disease. If this service is available in your area, save the tick and bring it in. Put the tick in a plastic bag that seals at the top, or in a jar. If you can't identify the tick and you were bitten in a part of the country where there's a risk of Lyme disease, contact your doctor. Discuss with the doctor if treatment, usually an antibiotic, is needed to lower the chance of Lyme disease.
