Make sure the tick is fully removed from the skin. Take a pain reliever if necessary (do not give aspirin to children -- it is associated with Reye syndrome in some viral illnesses). If complications develop, treatment will be aimed at controlling the symptoms.
Colorado tick fever usually goes away by itself and is not dangerous.
There is a risk for aseptic meningitis, encephalitis, and hemorrhagic fever, but these complications are extremely rare.
Call your health care provider if you are unable to fully remove a tick embedded in the skin, if you or your child develop symptoms of this disease, if symptoms worsen or do not improve with treatment, or if new symptoms develop.
