The problem with this article is that it's not really an unbiased view of the scientific literature; and the ArsTechnica author is not an expert (she has a Ph.D. in microbiology, but this really requires specialized knowledge of a virologist or infectious disease expert). ArsTechnica itself is also not unbiased.

No, but on the second page, they report on some studies which may be helpful in forming your own opinion.
