Thank you for bringing that up. Honestly, I didn't read in-depth into the autopsy of other infectious diseases.

But I looked through a few papers about influenza autopsy in PubMed using the relevant search terms (this is a hyperlink).

Most studies I see are not as detailed as Chertow et al.'s one, so I think it's difficult to make the comparison.

Most found that influenza virus (gene fragment and virus replication) mainly localizes to the respiratory tract and, to some extent, intestines only. Here is a nice quote from one of the studies that also cited other previous studies:

"Although viral [influenza A H5N1] RNA was found in various organs such as the intestine, heart, brain, spleen, kidneys, liver, lymph node, and placenta by reverse transcription-polymerase chain reaction (RT-PCR) and by in situ hybridization, viral antigen could be demonstrated only in the alveoli and a few other tissues [Uiprasertkul et al., 2005; Gu et al., 2007;Korteweg and Gu, 2008; Piwpankaew et al., 2010]. On the basis of these data, it was assumed that H5N1 virus replicated poorly in the extra-pulmonary tissues of humans [Uiprasertkul et al., 2005, 2007; Zhanget al., 2009]."
