  • Tillett et al. found evidence of SARS-CoV-2 re-infection by identifying two viruses with distinct genetic sequences corresponding to two different periods of illness in the same person. The two positive specimens were collected 48 days apart from a patient in Nevada. In between collection of the two positive samples, the patient made a full symptomatic recovery and had two negative SARS-CoV-2 tests.
  • The person involved was not using any immunosuppressive medications and does not have any significant immunological conditions.
