In 2021, Prof. Domingo performed a review of the scientific literature on the origin of SARS-CoV-2 in Environmental Research. One year after, because of the important advances on the knowledge of this virus, he has published an updated review in Environmental Research.

According to the results of the review, the origin of SARS-CoV-2 cannot be not established yet, although most papers point out to a zoonotic origin of this coronavirus. In any case, the hypothesis of an unnatural origin of SARS-CoV-2 cannot be yet scientifically discarded. Imoprtantly, most of the available papers on the origin of SARC-CoV-2 are not experimental studies.
