If it's a virus, it's not a bacteria... but anyway, I've never experienced it personally, but they're definitely transmitted from one infected animal to another. You'll want to thoroughly clean everything she's had contact with. Did they happen to say which corona virus? There are several different ones, depending on what species it primarily affects, dogs, cats, humans, rats, mice, even cows have their own variety. Glad she's doing okay though. Fast treatment is great!
