COVID-19 Infection among People with HIV/AIDS in Africa: Knowledge Gaps, Public Health Preparedness and Research Priorities.

The emergence of novel virus SARS-CoV-2 that causes COVID-19 has complicated Africa's public health challenges, especially with the pre-existing epidemics such as HIV/AIDS. We highlight the known evidence related to COVID-19 infections among people with HIV (PWH) with specific reference to Africa. The knowledge gaps, level of public health preparedness and the potential research priorities are also outlined. Although the epidemiology and clinical course of COVID-19 in HIV patients are evolving, existing evidence indicate that the disease outcomes are comparable to that of the general population. However, PWH with low CD4 cell counts may have worse outcomes than individuals with restored immunity, whereas old age and co-morbidities such as obesity, hypertension and diabetes can further increase their overall risk. While there may be slight disruption of HIV service delivery in selected African countries, the resilience and resourcefulness of others have helped to sustain HIV service delivery and enhanced the level of public health preparedness and fight against the pandemic. The paucity of data and research studies on HIV-COVID-19 coinfection in Africa, call for concerted efforts to address these limitations.
