Some reflections on comments

Recently Csabai et al. have found a metagenomic sample set originally collected at Antarctica that most likely as a result of
contamination contains traces of unique SARS-CoV-2 variants. Later on they identified putative host genomes. The preprints
resulted a wide discussion in the news and social media and some comments on the preprint server or via private emails. Here
we briefly reflect on some of them and present additional foreign sequences found in the same sample set.
