How do i know if i have pertussis?

Suspicion/duration: Since most adults have not bothered to get a pertussis booster, they represent a target of opportunity.Pertussis germs can ride into town in an international traveler or someone from the west coast & spread it to you (or your susceptible kids).In adults, it often seems to be a mild cold until you get past the initial phase, then the persistent "hundred days cough" sets in. Dx from test is possible.
