Trachoma

Description

Trachoma is the leading infectious cause of blindness in the world. Caused by the bacterium Chlamydia trachomatis, recurrent episodes of infection during childhood lead to severe conjunctival inflammation, followed by scarring, and consequent rubbing of the eyelashes on the cornea, increase the likelihood of blindness in later life. An estimated 137 million people are at risk of blindness from trachoma. The risk factors for trachoma are closely linked to lack of access to adequate water and sanitation and inadequate hygiene practices in communities, and it can be transmitted by routes such as direct person-to person contact, the vector Musca sorbens, and contact with cloths. Currently, trachoma remains endemic in 45 countries, so investment for promotion and health education of proper face and hand hygiene, provision of latrines, and installation of water sources in at-risk communities, coupled with the antibiotic distribution and surgery programs in place, are essential to the success of the SAFE strategy and the elimination of trachoma as a Public Health problem.
