Estudio corrobora que COVID-19 se originó en una pescadería china
An international study coordinated by the CNRS and the University of Arizona confirms that SARS-CoV-2 originated at the Huanan market in China. By analyzing open and public genomic data from China’s CDC, researchers identified the virus on surfaces of stalls selling wild animals, such as the raccoon dog and the civet. These findings strengthen the theory of an early zoonotic origin, directly linking the viral presence to species known to transmit coronaviruses similar to those infecting humans. The relevance of this article for the *open data* community is fundamental, as the conclusion relies entirely on the availability and reuse of genetic sequencing datasets published in accessible repositories. Although the earlier original study left some species identities unresolved, the researchers’ ability to reprocess, cross-reference, and analyze these public data was key to refining the understanding of plausible intermediate hosts. This demonstrates the value of scientific transparency and open access for accelerating epidemiological research. The implications of these results extend beyond the past, serving as a critical warning about the risks of interaction between wildlife and dense urban populations. The research underscores that, although laboratory safety has improved, insufficient measures have been taken to prevent future similar zoonotic scenarios. Therefore, understanding the precise origins of the pandemic, supported by robust and shared data, is essential for designing public health policies that protect global security and prevent future health crises.
