I’m not a vet or doctor… but I would say most likely no.
There are a couple diseases discussed in the article I linked to below: monkeypox and tularemia. However, the monkeypox was actually just a scare and “during this outbreak NO rabbit was EVER infected with monkeypox. […] HRS reminds the public that rabbits pose no risk of transmitting monkeypox to humans or to other species.” As for the tularemia, “Pet and domestic rabbits do not carry tularemia and therefore cannot infecta person with this disease. They pose no risk of tularemia infection to humans or to other animals, and fears concerning pet rabbits and tularemia are unfounded.”
So unless you have a wild bunny you don’t have to worry about tularemia. I’d just make sure your friend washes her hands thoroughly before going home. Changing clothes and putting the ones she wore to your house in the wash right away would also be good. Like fecal matter from any animal, there will be bacteria in your rabbit’s poop, but unless she was playing in it, she probably won’t have picked up anything. If your rabbit is sick, there might be more cause for concern; however, I volunteer at the shelter, and often spend hours cleaning sick cat cages. I’ve never caught anything – I use a scoop and make sure not to touch the soiled litter, and I wash my hands before I leave and then shower and wash my clothes right when I get home. Leroy (my rabbit) has never been affected either. Granted, I’m talking about sick cats and I’m completely healthy, so it’s probably a bit different, but still. Hope that helps!

Oh also, I’ve never caught anything from Leroy and he’s never caught anything from me. Then again, since I’ve had him, we’ve both been healthy.
