Monthly STD Report − June 2007
St. Charles County Department of Community Health and the Environment
Kristy Baumgart, MPH
For the month of June, St. Charles County had 37 laboratory confirmed STD cases (as of 7/29/07), which is much lower than the previous 2 Junes (67 cases in 2006 and 56 cases in 2005). Using the 2006 rough population estimate as the total population (n= 340,000) of St. Charles County, the incidence rate for STDs during June 2007 is 10.9 cases/100,000 people. For comparison, the incidence rate (using the 2005 population estimate of 329,940) for 2006 was 20.3 cases per 100,000 and for 2005 was 17.0 cases per 100,000. The graph below shows the number of diagnoses for each STD during the month of June in 2004, 2005, 2006, and 2007.
STD Counts for the Month of June
St. Charles County Department of Community Health and the Environment, 2004-2007
The chart below compares monthly STD case totals from 2004-2007. May 2007 was fairly typical for this County. This graph is intended to show the seasonality of STDs in St. Charles County.
The following chart shows the June 2007 rate of STD cases per zip code per 100,000 people, using the 2000 population estimates for each zip code. The rates most likely are inflated due to the current 2007 population estimate for each zip code.

The chart below is intended to see if the month of diagnosis has a relationship with the zip code of residence. Because St. Charles County has a significant college-aged population within a particular zip code, the relationship may prove helpful as the year progresses.
Percent of STD Cases per Zip Code, St. Charles County,
June 2007
As noted by the chart below, females clearly outnumber the number of males with lab-confirmed STDs; however during the past spring months, the difference between males and females was not as large, particularly in June. Because this difference may impact educational messages, we will continue to monitor the number of males diagnosed each month. Tailoring prevention messages to males may be an important tool for future educational programs.
The highest numbers of STD cases have occurred within the young adult population. Steps to improve STD interventions and/or education may need to be addressed. The month of June was very similar to previous years, where the large majority of cases occurred within the 15−24 year olds.
