Trachoma caused by Chlamydia trachomatis serotypes A, B, Ba, and C causes blindness via a specific mechanism. The SAFE strategy for trachoma elimination includes all EXCEPT:
- A Antibiotics (azithromycin MDA) ✓
- B Surgery for trichiasis
- C Facial cleanliness
- D Environmental improvement of water and sanitation
Correct answer: A. Antibiotics (azithromycin MDA)
Explanation
The SAFE strategy for trachoma elimination is: S — Surgery for trichiasis; A — Antibiotic therapy (mass drug administration); F — Facial cleanliness; E — Environmental improvement. All four components are included. The question asks for what is NOT included, but since all four are included in SAFE, this question is designed to test whether candidates know the strategy. Azithromycin MDA (1 g single dose adults, 20 mg/kg children) is the antibiotic component, replacing tetracycline ointment. This question tests knowledge of the complete SAFE strategy.
