How long was the child there ? It doesn't seem like he was there that long .... Wash everything that he touched and wash your hands well ..... It's only contagious by touching the eye and touching your eye so if he touched his eye and then touched a toy and then another kids touched the sane toy and then touched his eye .... You see what I'm saying ... So if he wasn't rubbing his eye ( cause pink eye is itchy) and if you didn't touch it then you should be good .... It is the kind of thing that can keep going around .... You can get over the counter drops for pink eye and I think 24 hours after dosage should be good ....
