The yet to be peer-reviewed study showed that a 22-year-old female with uncontrolled advanced HIV infection was persistently infected with SARS-CoV-2 beta variant for 9 months. As she stopped her HIV treatment, the virus accumulated "more than 20 additional mutations" in her body, said researchers from the Universities of Stellenbosch and KwaZulu-Natal, among others. However, with anti-retroviral therapy, the HIV was "suppressed" and COVID virus was "cleared within 6-9 weeks".
"Increased vigilance is warranted to benefit affected individuals and prevent the emergence of novel SARS-CoV-2 variants," the researchers said. The study demonstrated that COVID-19 may mutate rapidly in those whose immune system is weakened by HIV infection. It has already been observed that COVID-19 can linger for many months in patients who are HIV positive but who have, for varying reasons, not been taking the medicines that would enable them to lead healthy lives.
