oh, and if there are infants in any of those homes:

http://en.wikipedia.org/wiki/Pertussis#Prognosis

Infection in newborns is particularly severe. Pertussis is fatal in an estimated one in 100 infants under two months, and fatal in one in 200 infants aged two to 12 months. Infants under one are also more likely to develop complications (e.g., pneumonia (20%), encephalopathy, seizures (1%), failure to thrive, and death (0.2%)). Pertussis can cause severe paroxysm-induced cerebral hypoxia and apnea. Reported fatalities from pertussis in infants have increased substantially over the past 20 years.
