Impact of variant of concern and vaccination status on COVID-19 infection virological dynamics in end stage kidney disease patients receiving haemodialysis.

Our study suggests that patients infected during delta-variant period of COVID-19 illness, have higher viral load at presentation and prolonged viral shedding, especially in the unvaccinated cohort. However, prolonged time to negative PCR is likely due to inactive virus shedding, and that conversion to negative PCR may not be a necessary pre-requisite for de-isolation.
