Bloom aligned reads from 176 environmental samples to the SARS-CoV-2 genome and a panel of chordate mitochondrial genomes, then correlated per-sample SARS-CoV-2 read counts against each species’ mtDNA read counts. The virus tracks fish/livestock/human material (species handled or deposited by people throughout the market) at least as strongly as any susceptible mammal, and shows a negative association with raccoon dog and hoary bamboo rat. The ranking is analysis-choice-sensitive (excluding the first sampling timepoint makes Oriental rat snake most-correlated; linear vs log scale and non-zero-only subsets shift the ordering), but raccoon dog stays negative. Same China-CDC market set (D-1) that S-35 analyses toward the opposite emphasis.
