We report a 23% asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS
CoV-2) Omicron carriage rate in participants being enrolled into a clinical trial in South
Africa, 15-fold higher than in trials before Omicron. We also found lower CD4+ T-cell counts
in persons with human immunodeficiency virus (HIV) strongly correlated with increased
odds of being SARS-CoV-2 polymerase chain reaction (PCR) positive.

Abstract
We report a 23% asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) Omicron carriage rate in participants being enrolled into a clinical trial in South Africa, 15-fold higher than in trials before Omicron. We also found lower CD4 + T-cell counts in persons with human immunodeficiency virus (HIV) strongly correlated with increased odds of being SARS-CoV-2 polymerase chain reaction (PCR) positive.
