Dr Flavia Senkubuge Specialist Public Health Medicine University of Pretoria 28 February 2011
2
Introduction HIV&AIDS remains of Public Health concern in Africa
Significant strides made but much still to be achieved
3
Some statistics Sub-Saharan Africa- more heavily affected by HIV&AIDS compared to any other region of the world: 22.5 million people living with HIV in the region. 2009 around 1.3 million people died from AIDS in sub-Saharan Africa 1.8 million people became infected with HIV 14.8 million children have lost one or both parents to HIV/AIDS
4
Consequences far reaching!
Consequences of the AIDS epidemic are social and economic in: health sector Education Industry Agriculture Transport human resources and the economy in general
5
The triple challenge Providing health care, antiretroviral treatment, and support to people with HIV-related illnesses. Reducing the annual toll of new HIV infections Coping with the impact of AIDS deaths on national development, orphans and other survivors and communities.
6
The prevalences in Africa
HIV prevalence rates and the numbers of people dying from AIDS vary between African countries: Somalia and Senegal - HIV prevalence is under 1% of the adult population Namibia, Zambia, Zimbabwe % of adults are infected with HIV South Africa the HIV prevalence % Exceeding 20% Botswana (24.8%), Lesotho (23.6%) , Swaziland (25.9%).
7
The prevalences in Africa
Cameroon HIV prevalence - 5.3% Gabon - 5.2% Nigeria HIV prevalence - (3.6%) compared to the rest of Africa BUT 3.3 million people living with HIV HIV prevalence in East Africa more than 5% in Uganda , Kenya, Tanzania Rates of new HIV infections in sub-Saharan Africa appear to have peaked in the late 1990s HIV prevalence declined slightly, although remains at high level.
8
Impact HIV&AIDS in Africa
Life expectancy: Average life expectancy in sub-Saharan Africa years Households: Loss of income Home based care Orphans Healthcare: Increased demand- strain Affecting health care workers
9
Impact HIV&AIDS in Africa
Schools Affected severely Play role in education and support of HIV Productivity: Labour (15-49)– slow of economy Replacement due to ill-health Economic growth and development Severely affected therefore affecting Africa’s ability to cope
10
HIV Prevention Large scale HIV prevention initiatives – reduce scale of epidemics e.g Senegal, Uganda, Kenya, Burkina faso Condom use and 2005, eight out of eleven countries in sub-Saharan Africa reported an increase in condom use. Consideration (condoms)is cultural beliefs and norms and desire to have children Distribution of condoms to countries in sub-Saharan Africa has also increased: in 2004 the number of condoms provided to this region by donors was the equivalent of 10 for every man
11
HIV Prevention Provision of VCT – awareness of status leads to prevention in transmission and possible accesess to treatment ,care and support e.g Burkina Faso, Kenya, Tanzania, Malawi Mother-to-child transmission of HIV ,000 children in sub-Saharan Africa became infected with HIV Without interventions, there is a 20-45% chance that an HIV-positive mother will pass the virus on to her child With antiretroviral drugs, this risk can be significantly reduced.
12
Treatment and care Antiretroviral drugs (ARVs) - significantly delay the progression of HIV to AIDS and allow people living with HIV to live relatively normal, healthy lives Poor health systems – reduced delivery Not enough health care workers 4 in 10 not receiving ARVs Success number of people receiving ARVs in Africa doubled in alone end of 2009, almost 4 million people in Africa were receiving antiretroviral treatment
13
Treatment and care Initiatives: VCT Nutrition Follow up counselling
World Health Organisation (WHO) initiated the ‘3 by 5’ programme - three million people in developing countries on ARVs by the end of 2005. Latest international target, ‘All by 2010’- universal access to treatment by 2010. VCT Nutrition Follow up counselling Protection from stigma and discrimination Treatment of STI Prevention and treatment of opportunistic infection
14
Way forward International support Domestic commitment
Increased funding Domestic commitment Increased domestic expenditure Reducing stigma and discrimination Empowering women and girls HOW FAR IS YOUR COUNTRY ( DISCUSSION) – 15 mins
15
Conclusion Sustained and committed efforts are necessarily not only from international partners but from countries themselves if the fight against HIV& AIDS is to be won!
