• W4387580996 abstract "Abstract People living with HIV (PLHIV) are a unique population because of their altered immune systems and taking antiretroviral therapy (ART) that may modify risk of SARS-CoV-2. Evidence from sub-Saharan African countries suggests that, despite not having higher SARS-CoV-2 infection prevalence than HIV-negative persons, PLHIV suffer worse COVID-19 outcomes. We assessed the prevalence of SARS-COV-2 infection by HIV status in Zambia in July 2020. We analyzed data from three different concurrent SARS-CoV-2 prevalence surveys (household, outpatient-department, and health-worker) conducted in six districts of Zambia in July 2020. Information on demographics and medical history was collected. Nasopharyngeal swabs were used to screen for SARS-CoV-2 RNA using polymerase-chain-reaction (PCR) and blood specimens were screened for SARS-CoV-2 virus-specific antibodies using an enzyme-linked-immunosorbent-assay (ELISA). Test-specific SARS-CoV-2 prevalence was calculated. Multilevel logistic regression models were used to measure test-specific adjusted odd ratios (aORs) of SARS-CoV-2 positivity by HIV status, controlling for demographic and medical history. We analysed the outcomes of the two different tests separately. Among 7,092 participants, 4,717 (66.5%) consented to blood-draw and 4,642 (65.5%) consented to nasopharyngeal swab. Overall SARS-CoV-2 positivity was 9.4% by PCR and 3.8% by ELISA. SARS-CoV-2 prevalence detected by PCR was higher among PLHIV than HIV-negative respondents (12.4% vs 9.1%, respectively, OR: 1.4, 95% confidence intervals [CI]: 1.0-1.9) and lower by ELISA (1.9% vs 3.9%, respectively, OR: 0.5, 95%CI: 0.2-0.9). Among PLHIV, not being on ART was an independent predictor of SARS-CoV-2 PCR positivity (aOR: 5.24,95% CI: 1.19-22.22) but did not have a significant effect on ELISA results. During the first COVID-19 wave in Zambia, PLHIV were more likely to be acutely infected with SARS-CoV-2 but less likely to be seropositive than participants without HIV. Intervention programs could focus on early access to COVID-19 vaccinations, testing and ART might reduce COVID-19 morbidity among PLHIV." @default.
