Trachoma.

Area of Science:

• Ophthalmology
• Infectious Diseases
• Public Health

Background:

• Trachoma is the leading infectious cause of blindness globally and a major focus for the World Health Organization's 2030 elimination goal.
• It is caused by repeated Chlamydia trachomatis infections in childhood, leading to conjunctival scarring and potentially irreversible vision loss.
• Affected populations are often in impoverished, rural areas with limited access to water and sanitation, disproportionately impacting women and children.

Purpose of the Study:

• To review the global progress and challenges in eliminating trachoma as a public health problem.
• To highlight the effectiveness of the SAFE strategy (Surgery, Antibiotics, Facial cleanliness, Environmental improvement).
• To identify the need for new or intensified approaches to combat persistent and recurring trachoma.

Main Methods:

• The study is a review of the current status of trachoma elimination programs worldwide.
• It analyzes the impact and success of the SAFE strategy over the past two decades.
• It identifies areas with persistent or recrudescent active trachoma.

Main Results:

• The SAFE strategy has led to considerable success, with 21 countries eliminating trachoma by December 2024.
• Several other countries are on track to meet elimination targets soon.
• However, challenges remain due to persistent and recrudescent active trachoma in certain populations.

Conclusions:

• While significant progress has been made, the 2030 global trachoma elimination target faces challenges.
• Continued success requires the development and implementation of novel or intensified interventions.
• Accelerating elimination efforts is crucial in settings with persistent disease.
