Show abstract

We evaluated the probability of need for public health action against trachoma in Esmeraldas province, Ecuador. Compared to global references, seroconversion rates to Chlamydia trachomatis Pgp3 in children suggest high probability of action needed in rural villages (91%) and lower in more urban areas (32%), motivating further trachoma assessment.
