My three-year-old son has pinkeye. I just noticed the goop about half an hour ago. Our Pedi didn’t even ask to see him, just said he’d call in the scrip. And, uh, swim lessons were this morning, so my son spent 45 minutes in the pool. Think I should call the Y, or not bother? What are the odds the rest of us will get it?
And for the record, I had an uncharacteristic minor freakout about this. I don’t really even know why. My five-year-old daughter is napping, blissfully unaware of the oozing horror infestating her little brothers eyes.
IANAD, however this is MPSIMS and not GQ.
There are several different causes for Conjunctivitis. It can be Bacterial, Viral or Chemical. It can be contagious or not. It could have been caused by the pool water and just be a severe irritation.
It probably is a good idea to call the Y as it might be the pool water’s chemical mix that caused the problem. If it is bacteria & contagious, it is not possible to contaminate the pool but the kids mights have shared towels or something else where the bacteria could have been passed around.
As my goal was to thoroughly confuse you with my oddball knowledge on this subject, I hopefully succeeded. 
What did the Doctor say? You should be asking him.
BTW: assume your son if contagious and assume he will be rubbing his eyes. Be careful he does not pass it to the rest of your family by frequent hand washings for everyone.

Heh. I told the doc I suspected pinkeye and described the symptoms (redness inside the eyelids, mild discomfort, greenish-yellow goop). He agreed, pointed out it’s actually referred to as Conjunctivitus, got my pharm info and gave me instructions for applying the ointment. That was really the extent of the conversation. I’d be surprised if I was on the phone with him for more than two minutes.
I called the Y. The girl I talked to told me she’d let the aquatics staff know.
I was diagnosed with pink-eye yesterday. I was prescribed eye drops, one drop an eye, four times a day. I’ve only done three treatments so far and I already notice quite a difference. Good luck to your son on for a similarly quick recovery!
