In a recent edition of 'Mann Ki Baat', the Prime Minister of India announced a significant achievement in the nation’s public health journey India has been declared free from Trachoma, a bacterial eye infection that can cause permanent blindness if left untreated. This declaration marks the culmination of decades of concerted public health efforts, surveillance, and awareness campaigns aimed at eliminating the disease.

Know About Trachoma

Trachoma is a bacterial eye infection caused by Chlamydia trachomatis. It is classified as a contagious disease, typically spreading through direct contact with the eye or nasal secretions of an infected person, or via contaminated objects such as towels and clothes. Repeated infections lead to scarring of the inner eyelid, which eventually causes the eyelashes to turn inward and scratch the cornea a condition called Trachomatous Trichiasis (TT) leading to irreversible blindness.

Trachoma primarily affects marginalised communities living in overcrowded areas with poor sanitation, lack of clean water, and inadequate hygiene facilities. Children are the most vulnerable group, and the infection often spreads easily within families and communities.

Trachoma As A Global Concern

The World Health Organization (WHO) classifies Trachoma as a Neglected Tropical Disease (NTD) due to its prevalence in impoverished settings and the relative lack of global awareness. According to WHO estimates, approximately 150 million people globally are at risk of contracting Trachoma, with a high concentration in parts of Africa, Asia, and Latin America.

India’s Journey To Eliminate Trachoma

India has a long history of combating Trachoma, beginning with the launch of the National Trachoma Control Programme in 1963. Over the years, efforts to control the disease were integrated into broader public health initiatives such as the National Programme for Control of Blindness (NPCB) and later, the National Programme for Control of Blindness & Visual Impairment (NPCBVI).

Key milestones in India’s fight against Trachoma include:

• 2017: India was declared free of infectious trachoma, a landmark achievement following a national survey that found negligible levels of active infection.

• 2019–2024: Continued district-wise surveillance across the country ensured that any re-emergence was closely monitored and swiftly addressed.

• 2021–2024: India conducted the National Trachomatous Trichiasis (TT only) Survey in over 200 previously endemic districts, as per WHO guidelines. This survey was crucial to officially validate the elimination of Trachoma as a public health problem, not just the infectious stage.

The SAFE Strategy: WHO's Framework For Elimination

To achieve and sustain Trachoma elimination, the WHO promotes the SAFE strategy, a multi-pronged approach comprising:

• S – Surgery: To correct trachomatous trichiasis, the blinding stage of the disease.

• A – Antibiotics: Mainly azithromycin, used to treat and clear active infections.

• F – Facial Cleanliness: Promoting hygiene to reduce transmission of bacteria.

• E – Environmental Improvement: Ensuring better sanitation, access to clean water, and community-level hygiene to interrupt the cycle of infection.

India’s successful implementation of the SAFE strategy played a pivotal role in its recognition as a Trachoma-free nation.

Eliminating Trachoma is more than a medical achievement it represents progress toward universal health coverage, social equity, and the Sustainable Development Goals (SDGs), especially those related to health, clean water, and sanitation. It also reflects India’s commitment to improving the quality of life for its most vulnerable populations through evidence-based and inclusive public health initiatives.

Conclusion

India’s elimination of Trachoma as a public health problem is a testament to the power of persistent health policies, community engagement, and intersectoral cooperation. With effective surveillance, robust treatment strategies, and public awareness, the nation has not only conquered a major health challenge but also set an example for other countries battling preventable diseases.
