Well, I am about 99% positive my son got whooping cough from week one in Cooperstown. Especially now that NY has admitted to an outbreak of it. My daughter got it from him. Both had the boosters too!
So if you kid is coughing and you were in cooperstown go IMMEDIATELY and get on anti-biotics. If you don't catch it in the first few days, the damage is done and you are in for 4-6 weeks of nasty coughing for you kids. My daughter would throw up every night for 2 weeks.
