Introduction The COVID‐19 pandemic reached the African continent in less than three months from when the first cases were reported from mainland China. As COVID‐19 preparedness and response plans were rapidly instituted across sub‐Saharan Africa, many governments and donor organizations braced themselves for the unknown impact the COVID‐19 pandemic would have in under‐resourced settings with high burdens of PLHIV. The potential negative impact of COVID‐19 in these countries is uncertain, but is estimated to contribute both directly and indirectly to the morbidity and mortality of PLHIV, requiring countries to leverage existing HIV care systems to propel COVID‐19 responses, while safeguarding PLHIV and HIV programme gains. In anticipation of COVID‐19‐related disruptions, PEPFAR promptly established guidance to rapidly adapt HIV programmes to maintain essential HIV services while protecting recipients of care and staff from COVID‐19. This commentary reviews PEPFAR’s COVID‐19 technical guidance and provides country‐specific examples of programme adaptions in sub‐Saharan Africa. Discussion The COVID‐19 pandemic may pose significant risks to the continuity of HIV services, especially in countries with high HIV prevalence and weak and over‐burdened health systems. Although there is currently limited understanding of how COVID‐19 affects PLHIV, it is imperative that public health systems and academic centres monitor the impact of COVID‐19 on PLHIV. The general principles of the HIV programme adaptation guidance from PEPFAR prioritize protecting the gains in the HIV response while minimizing in‐person home and facility visits and other direct contact when COVID‐19 control measures are in effect. PEPFAR‐supported clinical, laboratory, supply chain, community and data reporting systems can play an important role in mitigating the impact of COVID‐19 in sub‐Saharan Africa. Conclusions As community transmission of COVID‐19 continues and the number of country cases rise, fragile health systems may be strained. Utilizing the adaptive, data‐driven programme approaches in facilities and communities established and supported by PEPFAR provides the opportunity to strengthen the COVID‐19 response while protecting the immense gains spanning HIV prevention, testing and treatment reached thus far.
BackgroundLimited data exists to inform contact tracing guidelines in children and HIV-affected populations. We evaluated the yield and additionality of household contact and source case investigations in Swaziland, a TB/HIV high-burden setting, while prioritizing identification of childhood TB.MethodsIn partnership with 7 local TB clinics, we implemented standardized contact tracing of index cases (IC) receiving TB treatment. Prioritizing child contacts and HIV-affected households, screening officers screened contacts for TB symptoms and to identify risk factors associated with TB. We ascertained factors moderating the yield of contact tracing and measured the impact of our program by additional notifications.ResultsFrom March 2013 to November 2015, 3,258 ICs (54% bacteriologically confirmed; 70% HIV-infected; 85% adults) were enrolled leading to evaluation of 12,175 contacts (median age 18 years, IQR 24–42; 45% children; 9% HIV-infected). Among contacts, 196 TB cases (56% bacteriologically confirmed) were diagnosed resulting in a program yield of 1.6% for all forms of TB. The number needed to screen (NNS) to identify a bacteriologically confirmed TB case or all forms TB case traced from a child IC <5 years was respectively 62% and 40% greater than the NNS for tracing from an adult IC. In year one, we demonstrated a 32% increase in detection of bacteriologically confirmed child TB. Contacts were more likely to have TB if <5 years (OR = 2.0), HIV-infected (OR = 4.9), reporting ≥1 TB symptoms (OR = 7.7), and sharing a bed (OR = 1.7) or home (OR = 1.4) with the IC. There was a 1.4 fold increased chance of detecting a TB case in households known to be HIV-affected.ConclusionContact tracing prioritizing children is not only feasible in a TB/HIV high-burden setting but contributes to overall case detection. Our findings support WHO guidelines prioritizing contact tracing among children and HIV-infected populations while highlighting potential to integrate TB and HIV case finding.
