Colorado tick fever

Last edited: 4/16/2026

Overview

Colorado tick fever (CTF) is a viral infection transmitted by the bite of the Rocky Mountain wood tick (Dermacentor andersoni), causing symptoms such as fever, headache, myalgia, and occasionally hepatitis or encephalitis 1.

Diagnosis

  • Clinical presentation includes sudden high fever, chills, headache, myalgia, and sometimes gastrointestinal symptoms 1.
  • Serological testing (IgM and IgG antibodies) is crucial for confirming diagnosis 1.
  • Polymerase chain reaction (PCR) can detect viral RNA early in the course of illness 1.

    • Management

  • Supportive care is the mainstay, including hydration, antipyretics, and analgesics 1.
  • No specific antiviral treatment is universally recommended; ribavirin has been used in severe cases but evidence is limited 1.
  • Hospitalization may be necessary for monitoring and supportive care in severe cases 1.

    • Special Populations

  • No specific guidelines provided in the abstracts regarding pregnancy, pediatrics, elderly, or comorbidities 1.

    • Key Recommendations

  • Confirm diagnosis using serological tests (IgM/IgG antibodies) and consider PCR for early detection (Evidence: Moderate 1).
  • Provide supportive care including hydration and symptomatic relief with antipyretics and analgesics (Evidence: Expert opinion 1).
  • Hospitalize patients with severe symptoms for close monitoring and supportive management (Evidence: Expert opinion 1).
