    Our objective was to assess human immunodeficiency virus (HIV) knowledge and sexual behaviors in 294 perinatally HIV-infected youth aged 18 to 25 years from a psychosocial support group in Kampala using a self-administered survey. Seventy-nine percent reported an undetectable viral load, 9.5% detectable, and 12% did not know. Of those with sexual partners, 19% did not know the HIV status of their partner, 64% knew negative, and 22% knew positive. Sixty-two percent disclosed their HIV status to their partner. Seventy-two percent of participants previously had sex, and of those, 57% were sexually active in the last three months. Sixty-eight percent of participants used methods to prevent pregnancy. Seventy percent of participants denied physical, sexual, or emotional intimate partner violence. There was good adherence to antiretroviral therapy and a high proportion of contraceptive use, highlighting the importance of integrating these topics into psychosocial support programs for youth living with HIV.

    Abstract Abstract Background The true burden of COVID‐19 in low‐ and middle‐income countries remains poorly characterized, especially in Africa. Even prior to the availability of SARS‐CoV‐2 vaccines, countries in Africa had lower numbers of reported COVID‐19 related hospitalizations and deaths than other regions globally. Methods Ugandan blood donors were evaluated between October 2019 and April 2022 for IgG antibodies to SARS‐CoV‐2 nucleocapsid (N), spike (S), and five variants of the S protein using multiplexed electrochemiluminescence immunoassays (MesoScale Diagnostics, Rockville, MD). Seropositivity for N and S was assigned using manufacturer‐provided cutoffs and trends in seroprevalence were estimated by quarter. Statistically significant associations between N and S antibody seropositivity and donor characteristics in November–December 2021 were assessed by chi‐square tests. Results A total of 5393 blood unit samples from donors were evaluated. N and S seropositivity increased throughout the pandemic to 82.6% in January–April 2022. Among seropositive individuals, N and S antibody levels increased ≥9‐fold over the study period. In November–December 2021, seropositivity to N and S antibody was higher among repeat donors (61.3%) compared with new donors (55.1%; p = .043) and among donors from Kampala (capital city of Uganda) compared with rural regions ( p = .007). Seropositivity to S antibody was significantly lower among HIV‐seropositive individuals (58.8% vs. 84.9%; p = .009). Conclusions Despite previously reported low numbers of COVID‐19 cases and related deaths in Uganda, high SARS‐CoV‐2 seroprevalence and increasing antibody levels among blood donors indicated that the country experienced high levels of infection over the course of the pandemic.
