Health Indicator Report of Chlamydia Cases

Infections caused by the bacterium Chlamydia trachomatis are the most frequently reported notifiable disease in Utah, with 7,542 cases reported in 2013. Two-thirds of the reported cases were among persons between 15 and 24 years of age. The overall rate for chlamydia in Utah in 2013 was 262 cases per 100,000 persons. Females with chlamydia are at risk for developing pelvic inflammatory disease (PID), and both men and women may become infertile as a result of untreated chlamydia. Untreated chlamydia infections can damage the reproductive systems of both males and females. Susceptibility to more serious infections such as HIV also increases when an individual is infected with chlamydia. In addition, pregnant women with chlamydia can pass the infection to their infant during delivery, potentially resulting in pneumonia or neonatal ophthalmia.

Chlamydia by Race/Ethnicity, Utah, 2013

Notes

Rates were calculated by dividing the number of cases within a race/ethnicity group by the population within that group and multiplying by 100,000.

Data Interpretation Issues

Reported chlamydia rates are calculated by dividing the number of cases within the population of interest by the total number of persons within that population, then multiplying by 100,000. It should be noted that rates within small populations are volatile; a small change in the number of cases can noticeably change the rate. This change may look significant, but, statistically, it may not be. Caution is strongly recommended when interpreting small case numbers and rates.

How Are We Doing?

Chlamydia rates in Utah have increased since 2000, however a slight decrease in rate (2.6%) was seen from 2012 to 2013. The overall rate increase can be attributed to increased screening efforts, use of increasingly sensitive diagnostic testing, efforts to increase reporting by providers and laboratories, and improved information systems for reporting. Such increased rates can be interpreted as an advancement in disease control as more infections are identified and treated, providing opportunity to intervene in the spread of infection. Chlamydial infections in both men and women are commonly asymptomatic, yet screenings occur more often among females, resulting in higher rates of reported infections among females. However, with the increased availability of urine testing, men are increasingly being tested for chlamydial infection. Over the past 10 years in Utah, the chlamydia rate in men increased by 82.5% as compared with a 55.2% increase in women over this period.

How Do We Compare With the U.S.?

Chlamydial infections are the most frequently reported notifiable disease in the U.S., with 1,422,976 cases reported in 2012. Of these reported chlamydia infections, 69.4% were among those 15 to 24 years of age. The overall rate for chlamydia in the U.S. in 2012 was 456.7 cases per 100,000 persons. The chlamydia rate in Utah is significantly lower than the U.S. rate. In 2012, Utah's chlamydia rate ranked 47th in the nation. [CDC. ''Sexually Transmitted Disease Surveillance'', 2012.] In Utah in 2013, persons aged 20 to 24 years reported the highest rates of chlamydia in both males and females. The rate for females in this age group in Utah during this timeframe was 1,576.9 cases per 100,000 persons compared with 3,695.5 cases per 100,000 persons in the U.S. in 2012. The rate for males aged 20 to 24 years in Utah in 2013 was 691.7 compared with 1,350.4 cases per 100,000 persons in the U.S. in 2012 [CDC. ''Sexually Transmitted Disease Surveillance'', 2012.]

What Is Being Done?

Persons who test positive for chlamydia are confidentially interviewed by a disease intervention specialist from their local health department to educate the patient, ensure proper treatment, and to obtain sexual partner information for follow up. This process helps prevent diagnosed individuals from spreading the infection and the patient from becoming reinfected. The Utah Department of Health Communicable Disease Prevention Program, along with local health departments, currently provide STD (sexually transmitted disease) presentations upon request to a variety of organizations, agencies, and facilities.

Available Services

Local health districts have STD (sexually transmitted disease) clinics located at their local health department(s) where individuals can be tested and treated for STDs at minimal or no cost. Planned Parenthood has locations throughout Utah that also provide STD services at minimal cost. Condoms are available at these locations. STD presentations are available through the Utah Department of Health upon request. The Utah Department of Health also has educational pamphlets available. The Utah Minor's Consent Law allows adolescents between the ages of 14 and 17 years to be tested and treated for an STD without the consent of a parent.
