Really gd annoying. The cough just doesn't stop and it's like it forces you to cough as hard as you can all the time. Easy to understand why young and old can die from it, but not the worst illness I've had. Last about a week with the cough being the worst in the first half.

I got a bronchitis infection years later though that may have been related to damage from the whooping, and I think that nearly killed me. The cough wasn't nearly as strong, but it was far more prevalent and lasted nearly three weeks, constantly preventing me from sleeping.
