Researchers found that SARS-CoV-2 (COVID-19) virus underwent more than thirty mutations in an African AIDS patient.
- The patient was diagnosed with AIDS back in 2006
- She contracted COVID-19 in September 2020 and tested positive for about 216 days
- During the period of infection, SARS-CoV-2 underwent mutations more than thirty times, two of which correlate with variants of concern
What is Immunosuppression?
Immunosuppression is the suppression of the immune response in the human body either partially or entirely. Some diseases can make people immunosuppressed, which in turn predisposes the body to infections. Immunosuppression can also be induced artificially by medications to help transplanted organs survive.Read More..





Highlights of the Case
The 36-year-old woman was diagnosed with AIDS back in 2006. She began to observe weakness and gradually became immunosuppressed. She tested positive for COVID-19 in September 2020 and carried SARS-CoV-2 for 216 days within her.During that period, the virus underwent more than 30 mutations in which 13 occurred to the spike protein, and 19 others caused genetic shifts in the viral genome.
Two of the viral mutations that occurred in her body seem to correlate with the mutations that created 'variants of concern.'
- E484K mutation, which is part of the Alpha variant B.1.1.7 (first seen in the UK)
- N510Y mutation, which is part of the Beta variant B.1.351 (first seen in South Africa)
Dr. Juan Ambrosini, associate professor of infectious diseases at the University of Barcelona, commented, "But it is probably the exception rather than the rule for people living for HIV because prolonged infection requires severe immunocompromise." In this case, the woman in the case study was immunosuppressed.
The study report of this exclusive COVID-19 case was published as a preprint in the medical journal medRxiv.
