My father had this go through his barn when my mare was there - she was only about 8-10 months at tht time (she's a rescue so we only know approxiamte birth date) She was still recovering from stavation at the time,  so she took a long while to get ever it - I would say probably 4 months before she was back to the condition she was in before strangles and at least another 2 months before she was back to normal body condition - though her growth was delayed a little - but most likely as much from the starvation as being sick.

Today she is a great looking 3 year old  - rising four now. No adverse effects at all and she's even caught up on her growth.

There were 2 other horses in the barn at the time (he thankfully had 3 out at a friend's facility when this happened) One other rescue survived (she was the carrier) and is still doing well but Dad lost the healthiest one, a 10 month old colt, to bastard strangles. Bastard strangles is rare, but most often fatal.

There were a few cases in the area when this came through - all carried by very poor horses that had come through an auction from out west when the drought's were happening. All horses except my father's one colt pulled through just fine.

I had a horse vaccinated for strangles and after being home less than a week from a trainers, he came down with strangles. 

I had four horses on the property, one to foal any day.  All four horses got strangles some worse than others. All had some form of break out with oosing puss.  My mare had strangles during foaling time and the babe was fine and never showed signs of strangles. She was lucky and had the benefit of her mother's colostrum.  My worse case was my 25 year gelding and he never got better, the vet said it was time so we put him down. 

It took two to four weeks for it to run it's course on all of them.  I had the gelding put down around four-five weeks and shouldn't have let him go that long, I just keep hoping he'd get better. 

If you've had the vet check him and he gives the OK, I wouldn't hesitate to buy if you really like the horse.   I still have two of the horses from that time and it's almost been six years and neither has any ill effects from that time.
