Screening for Chlamydia and gonorrhea: U.S. Preventive Services Task Force recommendation statement.

Area of Science:

• Preventive medicine
• Infectious disease screening
• Public health guidelines

Background:

• Sexually transmitted infections (STIs) like chlamydia and gonorrhea pose significant public health challenges.
• Previous U.S. Preventive Services Task Force (USPSTF) recommendations for screening were established in 2007 for chlamydia and 2005 for gonorrhea.
• An update was necessary to incorporate the latest evidence on screening effectiveness and harms.

Purpose of the Study:

• To update the USPSTF recommendations for screening for chlamydial and gonococcal infections.
• To evaluate the benefits and harms of screening in asymptomatic adolescents and adults, including pregnant women.
• To provide evidence-based guidance for clinicians on STI screening practices.

Main Methods:

• Systematic review of evidence on screening for chlamydia and gonorrhea in asymptomatic individuals.
• Inclusion of studies published since the last USPSTF reviews.
• Consideration of evidence from previous USPSTF recommendations and reviews.

Main Results:

• The USPSTF recommends screening for chlamydia in sexually active females aged 24 years or younger and in older women at increased risk (B recommendation).
• The USPSTF recommends screening for gonorrhea in sexually active females aged 24 years or younger and in older women at increased risk (B recommendation).
• Evidence is insufficient to assess the benefits and harms of screening for chlamydia and gonorrhea in men (I statement).

Conclusions:

• Routine screening for chlamydia and gonorrhea is recommended for young, sexually active females and at-risk older females.
• Current evidence does not support screening recommendations for men in either infection.
• Further research is needed to determine the optimal screening strategies for men.
