Virologist at Erasmus MC and coauthor of the Huanan market SARS-CoV-2 emergence study

Disputed An exact match for the sentence is reproduced as part of the abstract of the Zenodo preprint “The Huanan market was the epicenter of SARS-CoV-2 emergence” in contemporaneous coverage pointing to that same Zenodo preprint, and the Zenodo record itself shows a February 26, 2022 publication with 18 named authors, including Marion P. G. Koopmans. But the source is a multi-author paper, not a statement attributed to Koopmans alone, so this is a misattributed single-author quote on this platform.
