Popis: Initiation of NM/R treatment on Day 0 in a 71-year-old vaccinated and boosted male resulted in rapid resolution of COVID-19 symptoms followed one week later by the development of typical cold symptoms. SARS-CoV-2 viral load fluctuated in parallel with symptoms, with two distinct peaks on Day 1 and Day 9 of illness. No other respiratory pathogens were identified. Viral samples demonstrated sequence identity for the omicron subvariant BA.1 on Days 1, 7, and 11. Our findings suggest that viral replication and COVID-19 symptoms may recur after very early treatment with NM/R before natural immunity is sufficient to fully clear SARS-CoV-2.
