In a closed air system, it seems this would be a problem. It is strange to me that nobody had problems before getting on the plane. Or if they did, they certainly shouldn't have flown.

Yup, the recirculated air can't be beat as a means of bacterial transmission. Some have argued the problem has gotten worse since the airlines banned smoking and hence cut back on the rate of air replenishment.

The airline industry needs this, at this time, like a hole in the head.

One way to be sure to get treatment in the US, huh?
