Within 3 years, numerous mutations in the SARS-CoV-2 genome relevant to its fitness have resulted in a series of variants of concern (VOCs), such as Alpha, Beta, Gamma, Delta, and Omicron [1]. There is, however, one place the virus could have been hiding while it evolved into omicron that probably would have been in health officials' blind spot: inside the body of a single person. Specifically, a person whose immune system was suppressed — for example, as a result of an untreated HIV infection.
