Pertussis - Florida Health CHARTS - Florida Department of Health

Pertussis

Pertussis, also known as whooping cough, is a highly contagious respiratory disease caused by the bacterium Bordetella pertussis. Pertussis is known for uncontrollable, violent coughing which often makes it hard to breathe. Pertussis can affect people of all ages, but can be very serious, even deadly, for babies less than a year old. The best way to protect against pertussis is by getting vaccinated.

Pertussis is monitored because it is a highly contagious vaccine-preventable disease.

In 2024, the rate per 100,000 of Pertussis in Alachua County was 1.7 compared to Florida at 3.1. The line graph shows change over time when there are at least three years of data.

Data Note(s)

Merlin Code(s): 03390
This disease became reportable prior to 1992. Counts and rates include confirmed and probable cases of Pertussis
Data presented here are from Merlin, Florida's web-based reportable diseases and conditions surveillance system. Note that any data prior to 1992 are not maintained in Merlin and should be interpreted with caution.
Data in this report are aggregated by the date the case was reported to the Bureau of Epidemiology, Florida Department of Health. Cases are assigned to Florida counties based on the county of residence at the time of the disease identification, regardless of where they became ill or were hospitalized, diagnosed, or exposed.
Rates based on less than 20 cases are not reliable and should be interpreted with caution.
All population-based rates are calculated using July 1 Florida population estimates from the Florida Legislature, Office of Economic and Demographic Research.
This is primary, quantitative data.

Chart will display if there are at least three years of data.
Multi-year counts are a sum of the selected years, not an average.
Quartiles are calculated when data are available for at least 51 counties.
MOV - Measure of Variability: Probable range of values resulting from random fluctuations in the number of events. Not calculated when numerator is below 5 or denominator is below 20, or count or rate is suppressed. The MOV is useful for comparing rates to a goal or standard. For example, if the absolute difference between the county rate and the statewide rate is less than the MOV, the county rate is not significantly different from the statewide rate (alpha level = 0.05). When the absolute difference between the county rate and the statewide rate is greater than the MOV, the county rate is significantly different from the statewide rate. MOV should not be used to determine if the rates of two different counties, or the county rates for two different years, are statistically significantly different.
Denom - abbreviated for denominator.
Population estimates are not available for persons whose county of residence is unknown. Given this, the denominator and associated rate are not available.
* - Indicates the county rate is statistically significantly different from the statewide rate.
