A presentation at this year’s European Congress on Clinical Microbiology & Infectious Diseases (ECCMID), held online this year, will discuss the growing evidence that the beta SARS-CoV-2 variant first identified in South Africa is leading to more severe disease in people living with HIV, and that failure to clear SARS-CoV-2 infection in a patient with advanced HIV creates conditions that can lead to evolution of dangerous mutations in SARS-CoV-2.

Control of HIV with antiretroviral therapy could be the key to preventing such evolution of SARS-CoV-2 in patients with advanced HIV, how many lexapro to get high since clearance of the virus is compromised if HIV is allowed to replicate for a long time and results in major damage to the immune system.

“Evolved mutations lead to escape from neutralisation, which means antibodies made as a result of previous natural infection or vaccination would work less well to protect you from a new infection,” explains session presenter Dr. Alex Sigal, Africa Health Research Institute, KwaZulu-Natal, South Africa, and Max Planck Institute for Infection Biology, Berlin, Germany. “SARS-CoV-2 may mutate extensively within one person if infection persists.”

In his talk, Dr. Sigal will present a case study of a patient with advanced HIV who, despite having only mild COVID-19 illness, tested SARS-CoV-2 positive for 216 days. Genomic sequencing revealed shifts in the patient’s SARS-CoV-2 viral population over time, involving multiple mutations at key sites including the spike protein domain which SARS-CoV-2 uses to enter human cells. The evolved virus was tested and shown to have variant-like properties in terms of its ability to escape antibodies.
