Clinical characteristics of the case.

Plasma viral load (left y-axis), CD4⁺ cell count, and CD4⁺/CD8⁺ ratio (right y-axis) were measured at every study visit. Detection limit of the standard diagnostic viral load assay was <400 copies/ml (1997–1999: day 0–365 after diagnosis), <40 copies/ml (1999–2021: day 365–8340 after diagnosis), and <20 (2021--present: 8340--present after diagnosis). Additional ultrasensitive viral load PCR tests (<5 copies/ml) were performed and are depicted as red dots.
