Syphilis, Infectious

Syphilis is a sexually transmitted disease (STD) caused by the bacterium Treponema pallidum. It has often been called "the great imitator" because so many of the signs and symptoms are indistinguishable from those of other diseases. Infectious syphilis includes primary syphilis, a stage of syphilis infection characterized by one or more ulcerative lesions and secondary syphilis, a stage of infection characterized by localized or diffuse mucocutaneous lesions (e.g., rash — such as non-pruritic macular, maculopapular, papular, or pustular lesions). Patients can spread the disease to others during these stages.

Monitoring newly reported syphilis cases helps target prevention and educational programs to affected individuals and populations.

In 2023, the rate per 100,000 of Syphilis, Infectious in Alachua County was 27.1 compared to Florida at 19.3. The line graph shows change over time when there are at least three years of data.

Alachua County is in the fourth quartile for this measure. This means that relative to other counties in Florida, the rate per 100,000 of Syphilis, Infectious is less in about three quarters of the counties.

The map illustrates county data by quartile. A quartile map is presented when there are at least 51 counties with data for this measure.

Data Note(s)

Data Source: Florida Department of Health, Bureau of Communicable Diseases

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 is 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.

Bacterial STD, chlamydia, gonorrhea, congenital syphilis, early syphilis, infectious syphilis and total syphilis data are updated each year from 2006 to the most recent reporting year to ensure a case has not been counted more than once. This update is necessary because duplicate cases may occur when persons with a sexually transmitted disease diagnosis move to a different county, state or country.
Annually, the proportion of records with unknown attributes are as follows: unknown age 0.01%; unknown sex 0.13%; unknown race 21%; unknown ethnicity 23%. Exact counts are available by clicking "Unknown Race/Ethnicity/Sex Cases" link. Unknown cases are not included in rate calculation.
This is primary, quantitative data.
All population-based rates are calculated using July 1 Florida population estimates from the Florida Legislature, Office of Economic and Demographic Research.
