In South Africa, a country with one of the highest levels of HIV prevalence, HIV-positive adults are the source case for a large proportion of pediatric tuberculosis (TB) cases. Unfortunately, TB index cases are not consistently asked about their child contacts, not all child contacts present to the clinic for TB screening, and it remains unknown what proportion of child contacts receive isoniazid preventive therapy (IPT)—a highly effective treatment for preventing TB in these children, long recommended by the World Health Organization. Project SOAR is assessing whether a symptom-based screening approach by TB nurses in community health clinics is more effective than the standard of care (traditional tuberculin skin test) in improving the proportion of TB-exposed children initiated on IPT.
