The risk of developing long COVID has decreased significantly over the course of the COVID-19 pandemic, according to an analysis of data led by Washington University School of Medicine in St. Louis. Researchers attributed about 70% of the risk reduction to vaccination against COVID-19 and 30% to changes over time, including the SARS-CoV-2 virus’s evolving characteristics and improved detection and management of COVID-19.
The research is published July 17 in The New England Journal of Medicine. “The research on declining rates of long COVID marks the rare occasion when I have good news to report regarding this virus,” said the study’s senior author, Ziyad Al-Aly, MD , a Washington University clinical epidemiologist and global leader .
