This study examined whether incident cases of pertussis cluster in urban census tracts and identified community characteristics that predict high-incidence areas.
An ecological study design was used.
The study population included all persons diagnosed with pertussis from January 1,1986, through December 31,1994.
Maps of rates were constructed via a geographic information system and clustering was statistically confirmed.
Associations between pertussis rates and community characteristics were tested.
Mapping and statistical analysis revealed spatial clustering of pertussis.
Higher age-adjusted rates of pertussis infection were associated with higher proportions of residents below poverty level.
In urban areas, pertussis infection clusters in areas of poverty.
