The origin of COVID-19 is highly debated – most studies have focused on a zoonotic origin, but research from the journal Risk Analysis, examined the likelihood of an unnatural origin (i.e. from a laboratory.)
The results indicate a greater likelihood of an unnatural than natural origin of the virus. The researchers used an established risk analysis tool for differentiating natural and unnatural epidemics, the modified Grunow-Finke assessment tool (mGFT) to study the origin of COVID-19.
This risk assessment cannot prove the specific origin of COVID-19 but shows that the possibility of a laboratory origin cannot be easily dismissed.
