Objectives: Evidence indicates that people living with HIV (PLHIV) are more impacted by COVID-19. The burden of SARS-CoV-2 infection among PLHIV is unknown in Nigeria. Methods: We conducted repeated cross-sectional SARS-CoV-2 serosurveys in 14 states and the Federal Capital Territory in Nigeria among PLHIV who had an HIV viral load (VL) test during April 2022 to January 2023. Evidence of SARS-CoV-2 immunoglobulin G (IgG) antibodies was assessed using a multiplex bead assay to measure IgG to spike (S), receptor binding domain (RBD), and nucleocapsid (N) proteins to identify potential infection and/or vaccination status. Results: Between April 2022 and January 2023, 47,614 remnant VL samples were included and tested for SARS-CoV-2 antibodies. Seroprevalence of SARS-CoV-2 infection, defined as IgG antibodies to spike and RBD591 [S+] and nucleocapsid [N+], (S+N+), ranged between 21.1% (95% confidence intervals [CI]: 11.4-31.8) in Ekiti State in January 2023 to 71.4% (95% CI 71.9-81.9) in Gombe State in November 2022, with overall steady trends within and between states over time, across age and sex. Conclusion: High rates of SARS-CoV-2 antibody seroprevalence among PLHIV in Nigeria were observed. This underscores the need to understand the association between HIV and SARS-CoV-2 to inform strategies to reduce the threat posed by COVID-19.
