Monitoring transmission intensity of trachoma with serology

Donna Huber on June 5, 2023

Trachoma, caused by ocular Chlamydia trachomatis infection, is targeted for global elimination as a public health problem by 2030. To provide evidence for use of antibodies to monitor C. trachomatis transmission, we collated IgG responses to Pgp3 antigen, PCR positivity, and clinical observations from 19,811 children aged 1-9 years in 14 populations. We demonstrate that …

Evaluation of a Single Dose of Azithromycin for Trachoma in Low-Prevalence Communities
