Integrated serosurveillance to assess disease elimination in coastal Ecuador: onchocerciasis, yaws, and trachoma
Serologic surveillance found no evidence of <i>O. volvulus</i> or <i>T. pallidum</i> transmission, consistent with elimination. High Pgp3 seroconversion rates suggest ongoing <i>C. trachomatis</i> transmission in rural villages. Results highlight the value of integrated serologic surveillance and motivate in-depth trachoma surveillance in Esmeraldas.
