Summary of HIV Prevention Response and Modes of Transmission Analysis in Lesotho (March 2009)

Core Content

This document presents an analysis of the HIV epidemic and prevention response in Lesotho, conducted by a multi-agency team including the National AIDS Commission (NAC), Ministry of Health and Social Welfare (MOHSW), UNAIDS, and the World Bank. The study aimed to improve the understanding of the epidemic and align prevention efforts with evidence-based strategies to reduce new infections.

Main Findings

HIV Prevalence and Trends

• Lesotho has the third-highest adult HIV prevalence in the world at 23.2% (2008).
• The epidemic stabilized from around 2000 onwards.
• HIV prevalence in children under 15 is estimated to have peaked in 2007.
• HIV prevalence among women is significantly higher than among men (26% vs. 19%).
• Heterosexual transmission is the dominant mode of HIV spread in Lesotho.

Incidence

• Annual HIV incidence in adults stabilized at 1.7% (2007), with a peak of 3.6% in 1995.
• Annual incidence in children halved over the last 8 years to 0.17%.
• Prevention of mother-to-child transmission (PMTCT) coverage increased to 31% in 2007.

Heterogeneity in the Epidemic

• High HIV prevalence is observed in females (especially aged 15-30), urban populations, wealthier individuals, and those with lower education.
• Lower prevalence is found in males aged 15-30, rural populations, and those with no sexual partners in the last 12 months.
• Sexual concurrency is exceptionally high, with 24% of individuals reporting multiple concurrent partners in 2007, compared to 10% in the region.
• Male circumcision (MC) is not fully effective in Lesotho due to traditional practices and unhygienic conditions.
• Mobile populations (e.g., apparel workers, miners) are at higher risk due to transactional and commercial sex practices.

Structural Drivers of the Epidemic

• Labour migration, gender roles, social norms, alcohol use, and income inequality are key structural factors.
• Intimate partner violence and age-disparate relationships contribute to the spread of HIV among women.
• These factors are largely beyond individual control and require broader policy and structural interventions.

Prevention Response

Policy Context

• Lesotho has a comprehensive policy framework, including the National Strategic Plan (2006-2011), PMTCT guidelines, ART guidelines, and HCT guidelines.
• However, male circumcision is not addressed in current policies, and a National BCC Strategy is still in development.
• The ABC strategy (Abstain, Be faithful, Use condoms) is partially integrated, but the concept of "be faithful" is not effectively translated into local language or context.

Prevention Programmes

• 11 mass media/IEC programmes and 23 behavioural interventions were identified.
• Most programmes focus on the 12-35 age group, with limited attention to married couples and long-term relationships.
• Condom distribution faces challenges due to logistical issues and shortages at the peripheral level.
• HTC services are mainly implemented by MOHSW, with additional support from CHAL and other actors.

Strategic Information

• The "Know Your Status" (KYS) campaign has reached over 169,000 people by the end of 2007.
• Referral systems and post-test counseling are lacking, limiting the effectiveness of HTC services.
• PMTCT services are available in all districts, with 72% of positive mothers and 77% of babies receiving HAART or ARV prophylaxis by 2007.

Funding for HIV Prevention

Expenditure Overview

• Total expenditure on HIV prevention in FY2005/06 was M38.53 million, which dropped to M19.24 million in 2006/07.
• Prevention spending increased to M31.08 million in 2007/08, but remains substantially lower than FY2005/06.
• Only 10% of HIV/AIDS funding was allocated to prevention in 2006/07, with care and treatment receiving the largest share (33%).

Funding Distribution

• BCC interventions received only 2% of prevention funding in 2006/07.
• Condoms and STI interventions saw a significant drop in funding in year 2.
• PMTCT and PEP received increased funding in the second year of the NASA study.

Key Recommendations

Policy Level

1. Strengthen implementation of existing policies by capacitating providers and ensuring quality services.
2. Integrate "partner reduction" and concurrency into all future HIV prevention strategies.
3. Review the BCC strategy to ensure it is grounded in evidence about priority populations such as steady couples.

Programme Level

• Expand targeted prevention activities for mobile populations, migrating couples, and young people.
• Improve referral systems and post-test counseling to enhance the effectiveness of HTC services.
• Address structural drivers such as migration, gender inequality, and alcohol use through cross-sectoral collaboration.

Funding Level

• Increase investment in HIV prevention to match the scale of the epidemic.
• Ensure adequate funding for BCC and behavioural interventions.
• Allocate resources more effectively to district levels and targeted populations.

Conclusion

The study highlights that sexual concurrency and low male circumcision rates are major drivers of HIV transmission in Lesotho. Despite a comprehensive policy framework, the response is not fully aligned with the epidemic's characteristics, and funding for prevention remains inadequate. There is a clear need for evidence-informed strategies, policy alignment, and increased investment in prevention to effectively combat the HIV epidemic.
