  1. Fulltext. Nonocular chlamydia infection and risk of ocular reinfection after mass treatment in a trachoma hyperendemic area.

    Article - En anglais

    Fulltext.

    Purpose

    The presence of nasal discharge on a child's face increases the risk of active trachoma, suggesting that Chlamydia trachomatis in nasal secretions may be a possible source of ocular reinfection.

    The prevalence of chlamydia in nasal secretions and the risk of reinfection after mass treatment was investigated in a hyperendemic area of Tanzania.

    Methods

    In one village a total of 232 children aged 1 to 7 years were followed before and after mass treatment.

    Clinical trachoma, and microbiologic evidence of chlamydia, were assessed at baseline, 2 and 4 weeks into mass treatment, and 4 weeks after treatment stopped.

    The presence of chlamydia in ocular and nasal secretions was determined by polymerase chain reaction-enzyme immunoassay techniques.
