We are writing regarding the Letter entitled “Role of non‐structural Proteins in the Pathogenesis of SARSCoV‐2” from Ribeiro da Silva et al., published in Journal of Medical Virology(1). We welcome the discussion on published article, which could improve the science and clarify any controversial issues. This article is protected by copyright. All rights reserved.

in the absence of any experimental study, we would feel that the authors would agree that the analysis of full-length genomes during outbreak it is useful and could help in the identification of specific mutation that could be related (or not) to any possible differential clinical outcomes 3 . Despite the only use of bioinformatics-based analysis, which is unlike to explain the pathogenetic process underling the SARS-CoV-2 infection, we have been proposing hypotheses based on objective data analysis in our study. Whether the hypothesis is correct would require further experimental validation. No doubt, that the hypothesis may be wrong or maybe right and very likely experiments will be able to prove or disprove them. As the letter's authors says, experiments may be complex and time consuming while there is no a-priori guarantee that they will definitively clarify the phenomenon under study. The role of rigorous and state-of-the-art theoretical analyses, by means of bioinformatics and molecular epidemiology approaches, is to support rational design of experiments and help the interpretation of the results in the hope to speed up the process of knowledge acquisition 4 . We do hope that the letter's authors will undertake all the experiments necessary to decipher the biology and pathogenesis of this dreadful virus also taking into account our hypotheses.

Collaborations among groups with different expertise are necessary to fight and win the battle against emerging pathogens.
