COVID-19 knowledge, attitudes, and practices among people vulnerable to HIV in Uganda: A cross-sectional cohort...

People with behavioral vulnerability to HIV face barriers to healthcare engagement that may impede uptake of non-pharmaceutical and other interventions to prevent COVID-19. Understanding COVID-19 knowledge, attitudes, and practices in this population can inform disease prevention efforts during future pandemics.

From October 2022 to September 2024, we enrolled participants aged 14-55 years without HIV who endorsed recent sexually transmitted infection, injection drug use, transactional sex, condomless sex, and/or anal sex with male partners. At enrollment, we collected socio-behavioral data, including assessments of COVID-19 knowledge, attitudes, and practices. Robust Poisson regression with purposeful variable selection was used to estimate prevalence ratios with 95% confidence intervals for factors associated with COVID-19 preventive practices.

Among 418 participants, 228 (56.9%) were female, the median age was 21 years (interquartile range 19-24), and 362 (84.9%) reported sex work. Knowledge about SARS-CoV-2 transmission routes was high (95.4%) but lower for the consequences of genetic variants (48.5%-69.7%) and possibility for asymptomatic infection or transmission (66.7%-80.8%). Handwashing was practiced by 90.8% of participants in the preceding month, whereas mask-wearing (76.5%), avoiding symptomatic people (73.7%), and any history of COVID-19 vaccination (46.9%) were less prevalent. Males were more likely to report avoiding symptomatic people (adjusted prevalence ratio 1.16 [95% confidence interval 1.03-1.31]) and COVID-19 vaccination (1.30 [1.05-1.60]). Enrollment during the BQ.1/BQ.1.1 Omicron wave was associated with less mask-wearing (0.81 [0.67-0.99]) but more vaccination (1.59 [1.29-1.95]).

We observed variable COVID-19 knowledge and attitudes among Ugandan adolescents and adults with little impact on COVID-19 preventive practices. Efforts to address suboptimal uptake of disease preventive practices during this and future disease outbreaks will require more than just improving knowledge.
