prevention

While global prevalence of HIV infection (percentage of persons infected with HIV) appears to have stabilized in recent years, the global number of people living with HIV is increasing because of ongoing accumulation of new infections with longer survival times, measured over a continuously growing general population.

Across the world, a small but growing number of countries have reduced HIV prevalence through sound prevention efforts. The high rates of transmission of HIV result largely from failure to use the available and effective prevention strategies and tools, and poor coverage of HIV prevention programmes. HIV prevention services were only reaching 20% of people in need in 2005, while coverage for key populations at higher risk of exposure to HIV were considerably lower.

Effective HIV prevention programming focuses on the critical relationships between the epidemiology of HIV infection, the risk behaviours that expose to HIV transmission, and also addresses the collective social and institutional factors, such as sexual norms, gender inequality, and HIV related stigma, that will otherwise continue to fuel HIV epidemic. 

Risk behaviours are enmeshed in complex webs of economic, legal, political, cultural and psychosocial determinants that must be analyzed and addressed by policies that are also effectively implemented, and through scaled-up programming.

Comprehensive HIV prevention requires a combination of programmatic and policy actions that promote safer behaviours, reduce vulnerability to transmission, encourage use of key prevention technologies, promote social norms that favor risk reduction and address drivers of the epidemic. 

Effective prevention efforts focus on measures that directly support risk reduction by providing information and skills as well as access to needed commodities (such as condoms, sterile injecting equipment, and drug substitution therapy) for the populations most in need.  In short, national planners and policymakers must: 1) Know their epidemic; and 2) Set priorities accordingly. 

Prevention and treatment must be scaled up in a balanced way, to capitalize fully on synergies between the two.  Comprehensive HIV prevention requires a combination of programmatic interventions and policy actions that promote safer behaviours, reduce biological and social vulnerabilities to transmission, encourage use of key prevention technologies, and promote social norms that favour risk reduction. 

HIV prevention includes addressing an array of issues discussed in other thematic areas in the policy section of the website. Forging links among HIV prevention with related programmes and services such as sexual and reproductive health services and legal services for women, can also contribute to intensification of HIV prevention. Strong linkages as well as special efforts to reach those at higher risk and excluded from access to services will result in more relevant and cost-effective programmes with greater impact.

Essential Policy Actions for HIV Prevention

  • Ensure that human rights are promoted, protected and respected and that measures are taken to eliminate discrimination and combat stigma.
  • Build and maintain leadership from all sections of society, including governments, affected communities, nongovernmental organizations, faith-based organizations, the education sector, media, the private sector and trade unions.
  • Involve people living with HIV, in the design, implementation and evaluation of prevention strategies, addressing the distinct prevention needs.
  • Address cultural norms and beliefs, recognizing both the key role they may play in supporting prevention efforts and the potential they have to fuel HIV transmission.
  • Promote gender equality and address gender norms and relations to reduce the vulnerability of women and girls, involving men and boys in this effort.
  • Promote widespread knowledge and awareness of how HIV is transmitted and how infection can be averted.
  • Promote the links between HIV prevention and sexual and reproductive health.
  • Support the mobilization of community-based responses throughout the continuum of prevention, care and treatment.
  •  
  • Promote programmes targeted at HIV prevention needs of key affected groups and populations.
  • Mobilizing and strengthening financial, and human and institutional capacity across all sectors, particularly in health and education.
  • Review and reform legal frameworks to remove barriers to effective, evidence based HIV prevention, combat stigma and discrimination and protect the rights of people living with HIV or vulnerable or at risk to HIV.
  • Ensure that sufficient investments are made in the research and development of, and advocacy for, new prevention technologies.

    Nigeria / Prevention-PMTCT: HIV/Aids - Nigeria Accounts for 30 Percent Mother to Child Transmission

    Nigeria still accounts for over 30% cases of mother to child transmission of the HIV/AIDS virus during and after pregnancy, despite breakthrough by experts in the field to prevent the transmission. The director general of the National Agency for the Control of AIDS (NACA), Professor John Idoko who was speaking at the flag off of the National HIV/AIDS strategic framework/ plan yesterday in Abuja said this figure is a huge challenge and accounts for the global gap in the fight against the virus.
