Saw a bat trying to hide in my balcony yesterday. From that sight I'm paranoid if it had contaminated the clothes drying there. My son used a cloth mask that was drying there, hours later we noticed the bat trying to hide in the balcony floor ( it then flew away) . Is there a risk of rabies from this exposure (if the bat has touched the masks which we don't know). Should we consider administration of rabies vaccine?
