Actually the most common way is through aerosolized particles, meaning there is a ton of rat shit and piss somewhere in your living space (like an attic or crawlspace) and it gets into your air supply. Far less commonly but still possibly it can be through direct exposure to feces and urine, or even more rarely through a scratch/bite
Despite this it’s astoundingly rare. 20-50 cases annually for the entirety of the USA and less than 1000 from 1993-2022
