Colorado tick fever (CTF) is a viral infection caused by the Colorado tick fever virus (CTFV). It is transmitted to humans by the bite of an infected tick, usually the Rocky Mountain wood tick. Symptoms of CTF include fever, headache, muscle aches, and fatigue. In some cases, a rash may also appear. Treatment is usually supportive, and most people recover without any long-term effects. However, in rare cases, complications such as meningitis or encephalitis can occur.
