Association Between Duration of SARS-CoV-2 Positivity and Long COVID

Clin Infect Dis. 2023 Nov 30;77(11):1531-1533. doi: 10.1093/cid/ciad434.

Abstract

In an observational study, we analyzed 1293 healthcare workers previously infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), of which 34.1% developed postacute sequelae of SARS-CoV-2 infection (also known as long COVID). Using a multivariate logistic regression model, we demonstrate that the likelihood of developing long COVID in infected individuals rises with the increasing of duration of infection and that 3 doses of the BNT162b2 vaccine are protective, even during the Omicron wave.

Keywords: COVID-19; SARS-CoV-2 infection; long COVID; vaccine.
