African tick bite fever

Last edited: 4/15/2026

Overview

African tick bite fever (ATBF) is a tick-borne zoonotic disease caused by Rickettsia africae, primarily affecting travelers and individuals in enzootic regions of sub-Saharan Africa [Not directly addressed in provided abstracts].

Diagnosis

  • Clinical presentation includes fever, headache, myalgia, and eschars at the site of tick bite [Not directly addressed in provided abstracts].
  • Serological tests (IFA, ELISA) are crucial for confirming diagnosis [Not directly addressed in provided abstracts].
  • PCR from eschar swabs or blood can provide rapid confirmation [Not directly addressed in provided abstracts].
  • Management

  • First-line treatment involves doxycycline (adult dose: 100 mg twice daily for 5-7 days) [Not directly addressed in provided abstracts].
  • Alternatives include tetracycline or minocycline, though doxycycline is preferred [Not directly addressed in provided abstracts].
  • Supportive care includes hydration and management of symptoms [Not directly addressed in provided abstracts].
  • Special Populations

  • No specific management guidelines provided for pregnancy, pediatrics, elderly, or comorbidities based on the given abstracts [Not directly addressed in provided abstracts].
  • Key Recommendations

  • Use doxycycline as the first-line antibiotic treatment for African tick bite fever (Evidence: Expert opinion [Not directly addressed in provided abstracts]).
  • Serological tests (IFA, ELISA) are essential for confirming the diagnosis of ATBF (Evidence: Expert opinion [Not directly addressed in provided abstracts]).
  • Supportive care measures should be implemented alongside antibiotic therapy to manage symptoms effectively (Evidence: Expert opinion [Not directly addressed in provided abstracts]).
