Weekly Epidemiological Record. WHO Alliance for the Global Elimination of Trachoma by 2020: progress report on elimination of trachoma, 2018; 2019
Trachoma, caused by particular serovars of Chlamydia trachomatis, is the leading infectious cause of blindness. Infection is transmitted within ocular and nasal secretions that are passed from person to person on fingers, fomites (such as bedding) and eye-seeking flies (particularly Musca sorbens). Ophthalmic infection is associated with an inflammatory conjunctivitis known as “active trachoma”.
