I've only read the abstract, and it seems to clearly say that the virus can get to the brain via the lungs. So I have no idea what people ITT are on about regarding purposeful infection or masks for prevention. Regardless, this abstract also does not explain the mildness of the disease except for the immunocompromised and elderly, which to me renders the link between how you get the infection and fatality a bit suspicious.
If you read more than the abstract, it explains that animals that are infected nasally have much higher rates of brain infection than the fecal-oral route of infection.
Edit: changed "oral/fecal" to "fecal-oral," thanks calmworm. Also removed a period.
