Complete Indicator Profile of Chlamydia Cases (HA2020 Leading Health Indicator: 18)

Definition

Rate of newly reported cases of Chlamydia trachomatis by date of diagnosis per 100,000 population.

Numerator

Number of newly reported cases of chlamydia by date of diagnosis for a specific time period.

Denominator

Mid-year resident population for the specific time period.

Why Is This Important?

Chlamydia trachomatis (CT) infection is the most commonly reported bacterial sexually transmitted disease in the US and in Alaska. Chlamydia is known as a 'silent' infection because most infected people have no symptoms. Untreated CT infection can cause pre-term labor, pelvic inflammatory disease (PID), ectopic pregnancy, and infertility in women; epididymitis and Reiter's syndrome in men; and eye infection and pneumonia in newborns. Alaska has consistently had the first or second highest (CT) infection rate in the nation since 2000.[1]

Healthy People Objective STD-1:

Reduce the proportion of adolescents and young adults with Chlamydia trachomatis infections
U.S. Target: Not applicable, see subobjectives in this category
State Target: Healthy Alaskans 2020 Target: 705.2 per 100,000

How Are We Doing?

Chlamydia rates in Alaska have increased since 2000. This 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 chlamydia infection control as more infections are identified and treated, providing opportunity to intervene in the spread of infection.

Chlamydia infections in both men and women are commonly asymptomatic, yet screenings occurring mostly among females produce higher rates of reported infections. However, with the increased availability of urine testing, men are increasingly being tested for Chlamydial infection.

How Do We Compare With U.S.?

Chlamydia rates in Alaska are significantly higher than rates in the U.S.

What Is Being Done?

Persons who test positive for chlamydia are confidentially interviewed by a local public health nurse to educate the patient, ensure proper treatment, and to obtain sexual partner information for follow up. This process helps prevent reported cases from spreading disease and the patient from becoming reinfected.

Available Services

Federallly Qualified Health Centers have STD clinics where adolescents can be tested and treated for STDs at minimal or no cost. Planned Parenthood has locations throughout Alaska that also provide STD services at minimal cost. Condoms are available at these locations.

Relevant Population Characteristics

Due to anatomical and hormonal differences, women are more susceptible to acquiring chlamydia than men. Therefore, women carry an excessive proportion of the chlamydia burden.

Adolescent and young adult males and females have a higher incidence of chlamydia. This can be attributed to increased risky sexual behavior among adolescents and young adults, biochemical differences increasing transmission rates, and increased screening among this age group.

Health Care System Factors

Chlamydia rates in Alaska have generally increased since 2000. This 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.

Risk Factors

Risk factors for sexually transmitted diseases include:
- sexual activity among young adults 25 and younger
- multiple sex partners
- prior history of STDs
- unprotected sex
- sexual contact with prostitutes (male or female)
- illicit drug use

Those who fall within one or more of these categories should be tested for STDs in regular intervals. Sites of infection may include pharynx, rectum, vagina, cervix, and urethra. Due to anatomical and biochemical differences, women are also at increased risk for acquiring chlamydia than men.

Health Status Outcomes

Untreated chlamydia in women may advance to PID (pelvic inflammatory disease), resulting in an ectopic pregnancy, preterm delivery, or infertility. Untreated chlamydia in men may result in infertility.
