HIV surveillance in MENA: recent developments and results

Area of Science:

• Epidemiology
• Public Health
• Infectious Disease Surveillance

Background:

• The Middle East and North Africa (MENA) region faces significant public health challenges related to HIV/AIDS.
• Effective HIV surveillance is crucial for understanding epidemic trends and guiding public health interventions.

Purpose of the Study:

• To evaluate the development and quality of national HIV surveillance systems across 23 MENA countries between 2007 and 2011.
• To assess the capacity of these systems to track HIV epidemic trends.

Main Methods:

• A questionnaire-based survey was administered to National AIDS Programmes in 23 MENA countries.
• System quality was assessed using indicators for data timeliness, population appropriateness, temporal consistency, and coverage.

Main Results:

• Only four countries demonstrated consistent tracking of HIV epidemic trends in specific at-risk populations (e.g., pregnant women, injecting drug users, sex workers).
• Established HIV infections in key populations were evident in nine MENA countries.
• Elevated HIV prevalence was observed in lower-risk populations in South Sudan, Djibouti, and parts of Somalia.

Conclusions:

• HIV surveillance systems in several MENA countries have improved.
• The scope of HIV epidemics in high-risk groups remains unclear in 10 countries.
• Integrating multiple data sources is essential for estimating HIV epidemic patterns and response effectiveness.
