Trachoma

Trachoma, which is the commonest infectious cause of blindness, is caused by Chlamydia trachomatis. Children who have the active stages of the disease are the reservoir of infection, while blindness, which occurs after repeated episodes of infection, principally affects adults. Boys and girls are equally affected by active infection, while blindness is more common in women. Trachoma is a condition of poverty and is a focal disease, affecting communities that have poor water supplies and sanitation and poor health services. The organism is transmitted from person to person through direct and indirect contact and by flies. Blindness can be prevented by surgery to correct in turning of the upper lid (trichiasis), while the infection and its transmission can be reduced with surgery, antibiotics, facial cleanliness and environmental change (the SAFE strategy).

 

Achievement to date:

Al l 75 districts of Nepal have been mapped for trachoma prevalence;

20 districts were found as trachoma endemic districts having prevalence of active trachoma more than 10%;

WHO recommended SAFE strategy was implemented in trachoma endemic districts;

SAFE stands for; “ S” for Surgery,  “A” Antibiotics, “F” for face washing , “E” for environment improvement;

27,974 TT surgery were performed for sight restoration;

1,47,090,21 doses of “Zithromax” antibiotics were administered since 2002 to till date;

Face washing & environmental improvement activities were conducted in collaboration with Department of Water Supply & Sewerage (DWSS) in all trachoma endemic districts;

Massive IEC materials were distributed to create public awareness in all trachoma endemic districts;

Surveillance Survey after 2 years of conduction of Impact survey was completed in 10 SAFE implemented districts;

Now, the prevalence of trachoma after surveillance survey is found less than WHO elimination thresholds.

 

Future Plan:

Complete remaining surveillance survey in 10 districts;

Plan to conduct surveillance survey II round in India bordering districts;

Plan to carry out M&E and interaction program on trachoma surveillance in non-bordering trachoma SAFE implemented districts;

Hold a District & National level stake holders meeting;

Continue the TT surgery for reported cases;

Continue the cooperation with DWSS for F&E components.
