SARS-CoV-2 pathogenesis is very complex and not fully understood yet. Here, Jeong et al. show that intranasally infected K18-hACE2 transgenic mice develop ocular infection and retinal inflammation, while intratracheal infection results in the dissemination of SARS-CoV-2 from mouse lungs to their brain and eyes via unidirectional route and confirm the tissue tropism in Syrian hamster model.
