The origin of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is contentious. Most studies have focused on a zoonotic origin, but definitive evidence such as an intermediary animal host is lacking. We used an established risk analysis tool for differentiating natural and unnatural epidemics, the modified Grunow–Finke assessment tool (mGFT) to study the origin of SARS‐COV‐2. The mGFT scores 11 criteria to provide a likelihood of natural or unnatural origin. Using published literature and publicly available sources of information, we applied the mGFT to the origin of SARS‐CoV‐2. The mGFT scored 41/60 points (68%), with high inter‐rater reliability (100%), indicating a greater likelihood of an unnatural than natural origin of SARS‐CoV‐2. This risk assessment cannot prove the origin of SARS‐CoV‐2 but shows that the possibility of a laboratory origin cannot be easily dismissed. [ABSTRACT FROM AUTHOR] |
