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

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.
