Pertussis Incidence rate

This indicator shows the Pertussis Incidence rate per 100,000 population. Pertussis is a cough illness lasting at least 2 weeks with one of the following: paroxysms of coughing, inspiratory "whoop," or posttussive vomiting, without other apparent cause (as reported by a health professional). Infants aged <1 year, who are at greatest risk for severe disease and death, continue to have the highest reported rate of pertussis across the US. School-aged children 7-10 years continue to contribute a significant proportion of reported pertussis cases; however, 2012 data indicate that pertussis is increasing among adolescents 13 and 14 years of age across the country.

Understanding the color Range

Each Health Indicator includes five-color range indexes. The color range index compares all counties in the state that have the same indicator in the same timeframe. It then calculates where the selected county falls in that range and displays the color that best reflects how the county is doing in comparison to the other counties in the filtered group. The range displays the highest and lowest county values within the state that have the same indicator for the same measurement period.

Current county values will be compared to State and National values if they are available.

Green and red arrows indicate that the county value is better or worse than the state or national value. The arrows will change directions and colors based on which end of the range is positive.
This icon simply means that the county value is equal to the state or national value.
Some indicators display blue, which means the data is not meant for health-status comparison, but is intended simply to provide information.
If history data is available the trend icon will point up or down based on its relationship to the last county value.
