The provider will make sure the tick is fully removed from the skin.

You may be told to take a pain reliever if you need it. DO NOT give aspirin to a child who has the disease. Aspirin has been linked with Reye syndrome in children. It may also cause other problems in Colorado tick fever.

How do I prevent Colorado Tick Fever?

When walking or hiking in tick-infested areas:

Wear light-colored clothing, which shows ticks more easily than darker colors. This makes them easier to remove.

Check yourself and your pets frequently. If you find ticks, remove them right away by using tweezers, pulling carefully and steadily. Insect repellent may be helpful.
