Hello, My Family Just Fostered A Rescue Chihuahua Dog (found

Hello,

My family just fostered a rescue Chihuahua dog (found him on side of the road) We had him at home for 24 hours , and then turned him over to a reputable rescue. They said because it appears that he has ringworm-(has not been tested yet) that we are all at risk for contracting ringworm. Besides washing everything that he touched-bedding etc... what are our chances of contracting ringworm which I know is a fungus. Thanks
