Sexually Transmitted Disease (STD) Surveillance Report, 2004 Minnesota Department of Health STD Surveillance System Minnesota Department of Health STD Surveillance System
Introduction This slide set describes new cases of chlamydia, gonorrhea, and syphilis in Minnesota by person, place, and time. The slides display data from cases diagnosed through 2004 and reported to the Minnesota Department of Health (MDH) STD Surveillance System. Data analyses exclude federal and private prisoners.
Introduction STD Surveillance is the systematic collection of data from cases for the purpose of monitoring the frequency and distribution of STDs in a given population. STD surveillance data are used to detect problems, prioritize resources, develop and target interventions, and evaluate the effectiveness of interventions.
Interpreting STD Surveillance Data Factors that impact the completeness and accuracy of the data include: Level of STD screening and individual test-seeking behavior Sensitivity of diagnostic tests Compliance with case reporting Timeliness of case reporting Increases and decreases in STD rates can be due to actual changes in disease occurrence and/or changes in one or more of the factors described above. For example, in 2002 MDH added an active component to the previously passive STD Surveillance System. As a result, compliance with reporting improved and the number of chlamydia and gonorrhea cases reported to MDH increased by at least 7% and 5%, respectively, between 2001 and 2002 as an artifact of reporting.

Increasing Prevalence of Drug-Resistant Gonorrhea in Minnesota STDs in Minnesota: Annual Review
Background Information CDC-recommended antibiotic treatments for gonorrhea: Ceftriaxone Single dose therapy, administered by injection Relatively expensive Cefixime Single dose therapy, administered orally Production discontinued in 2002; No longer available Ciprofloxacin, Ofloxacin, Levofloxacin (Quinolones) Single dose therapy, administered orally Spread of quinolone-resistant N. gonorrhoeae (QRNG) threatens the efficacy of fluoroquinolones as the frontline treatment for gonorrhea
Prevalence of Quinolone-Resistant N. Gonorrhoeae ( QRNG) s QRNG prevalent in Asia, >40% in some countries Hawaii discontinues use of fluoroquinolones following increase in QRNG prevalence from 1.4% in 1997 to 9.5% in 1999 California discontinues use of fluoroquinolones after reaching QRNG prevalence of 5% in 2001 Increases in QRNG reported in other U.S. states (e.g., MI, MA) CDC recommends non-quinolone therapy for infections acquired in HI, CA, and other areas with high QRNG prevalence 2004 Prevalence of QRNG in MN five times higher than in 2002

The Red Door Clinic in Minneapolis is one of the participating clinics. The data shown has been collected through this project.
Characteristics of the 2004 QNRG cases (n = 28) 71% 0f the cases were White 32% of cases (9) were among men under 30 years of age, the average age for cases was 32.5 years 22 of the 28 cases (79%) were among gay/bisexual males Eighteen percent of cases among gay/bisexual males were also HIV+ A majority of cases reported having multiple sex partners in the previous 60 days Two of the cases reported travel and sexual activity in areas with high QNRG prevalence (Philippines and Hawaii)
What’s Being Done in Minnesota? MDH has expanded the current QRNG surveillance system to include women and Room 111 in St. Paul MDH will use the data to guide future treatment recommendations Healthcare providers are encouraged to obtain travel histories of patients and to be alert for treatment failures. Gonorrhea infections acquired in areas with high QRNG prevalence and among MSM should receive non-quinolone therapy Clinicians and laboratories are asked to report suspected treatment failures and resistant gonococcal isolates to MDH MDH Partner Services Program follows up on cases and sex partners

Data Source: Minnesota STD Surveillance System STDs in Minnesota: Annual Review While the number of cases in 2004 decreased, first quarter data for 2005 indicate an increase back to 2003 levels Despite the decrease in 2004, cases among MSM remain high compared to 2001 (34 versus 5) MSM accounted for 81% of cases among males Internet was the most common venue for meeting partners (78%) Among MSM, most reported having anonymous sex (81%), and of these 41% reported no condom use Early Syphilis* among Gay/Bisexual Men Minnesota, 2004 * Early Syphilis includes primary, secondary, and early latent stages of syphilis.
What’s Being Done in Minnesota? MDH is continuing awareness campaigns (e.g., Health Notices, press releases) Encouraging physicians to screen gay/bisexual men at least annually Community-based programs intensifying outreach activities to reach gay/bisexual men MDH has implemented innovative prevention strategies (e.g., internet banners, partnering with venues) MDH Partner Services Program continues to follow up on cases and sex partners
Doubling of the Chlamydia Rate Since 1996 STDs in Minnesota: Annual Review
Data Source: Minnesota STD Surveillance System STDs in Minnesota: Annual Review Chlamydia in Minnesota Rate per 100,000 by Year of Diagnosis, per 100, per 100,000
Chlamydia Rates in Minnesota, Since 1996 the rate of Chlamydia infection has doubled from 115 to 236 per 100,000 The rate has doubled both among men (54 to 126) and women (175 to 343) Rates have almost tripled among year olds (214 to 597) and among year olds (56 to 156) Among year olds rates have increased 1½ times (640 to 968) and among year olds rates have doubled (567 to 1372)
Chlamydia Rates in Minnesota, Rates have also increased by race, doubling among Hispanics, Whites and Asian/Pacific Islanders In this time period, the chlamydia rate for Blacks and American Indians increased by 32% and 60%, respectively Rates have also increased by geography with the most marked increases happening in Greater Minnesota and the suburban 7- county metro area In both areas the rate more than doubled, compared to an increase of 25% in Minneapolis and 64% in St. Paul
Data Source: Minnesota STD Surveillance System STDs in Minnesota: Annual Review What’s Behind the Increase? 1.Improved testing technology with increased sensitivity 2.Improved screening practices by clinicians 3.Addition of active surveillance component 4.Increase of the disease in the population However, the effect of the first three factors would have leveled off over time so the increase is most likely being driven by an actual increase of the disease in the population. The observed increase since 1996 is most likely due to the combination of four factors:
SURVEILLANCE SUMMARY
Data Source: Minnesota STD Surveillance System STDs in Minnesota: Annual Review Summary of STD Trends in Minnesota Between , the overall chlamydia rate increased while rates of gonorrhea and early syphilis decreased STD rates continue to be highest in Minneapolis and St. Paul STD rates are highest among persons of color Chlamydia and gonorrhea rates are highest among adolescents and young adults; syphilis rates are highest among adults While the number of early syphilis cases is down, the numbers among gay/bisexual men are continue to be high Prevalence of antibiotic-resistant gonorrhea has increased five fold between 2002 and 2004
