Chlamydia control activities in Europe: cross-sectional survey

Area of Science:

• Public Health
• Epidemiology
• Infectious Disease Control

Background:

• Chlamydia is Europe's most frequently reported bacterial sexually transmitted infection.
• The Screening for Chlamydia in Europe (SCREen) project aimed to map chlamydia control efforts.
• Significant variation exists in chlamydia control strategies across European nations.

Purpose of the Study:

• To document current and planned chlamydia control activities in Europe.
• To categorize chlamydia control strategies using a standardized typology.
• To assess the relationship between economic factors and chlamydia control intensity.

Main Methods:

• A 2007 questionnaire was distributed to public health and clinical experts in 33 European countries.
• A five-category typology based on sexually transmitted infection control principles was developed.
• Country responses were used to assign each nation to a control activity category.

Main Results:

• 29 countries responded; 45% had no current chlamydia control activities.
• Control activities ranged from case management guidelines to opportunistic testing and screening programs.
• No significant association was found between GDP and the intensity of chlamydia control efforts (P = 0.816).

Conclusions:

• A new classification system effectively categorizes national chlamydia control activities.
• Prioritizing clinical guidelines for diagnosis and case management is essential.
• Screening programs should be considered only after robust diagnostic and management protocols are in place.
