Exploring the dynamics of SARS-CoV-2 and HIV Co-infection: Mutation risks, therapeutic efficacy, and future variant prevention

Abstract

High mutation rates in SARS-CoV-2, particularly among immunocompromised patients living with HIV, continue to complicate the current COVID-19 pandemic. The threshold for severe COVID-19 and a greater risk of mortality have increased in many immunocompromised individuals due to a weakened immune system. Low CD4+ T-cell counts in people living with both HIV and COVID-19 lead to prolonged disease duration and, therefore, an increased likelihood of viral infection with SARS-CoV-2 mutations in such individuals. These mutations could decrease the efficiency of ongoing vaccines and cause new outbreaks. Recently, the rise of new mutations in this patient population has created increasing concern; however, few data are currently available on the direct association of HIV infection with SARS-CoV-2 mutations. This review highlights the implications of SARS-CoV-2 and HIV co-infection, highlighting the need for extra caution and monitoring of the immune-compromised population during a pandemic. Access to HIV care and COVID-19 treatments, careful surveillance, and adapted health strategies are key to reducing risks and protecting these populations. Further research is required to elucidate the dynamics of mutations and develop intervention methods to manage COVID-19 among immunocompromised patients.
