A friends ds (15 months) has conjunctivitis (pink eye) and I have a 16 month old dd. They want to come and visit on Wednesday but I am rather apprehensive. Apparently he woke up yesterday morning with the infection. She plans to get antibiotics for him today and says that the second he starts taking these, he is no longer infectious. I said I wasnt entirely sure of that. Frankly, I do not want them to come around. Does anyone know how long conjunctivitis is contagious for and if you take antibiotics, does this really mean the infection is no longer contagious?
