A Global CrisisNumber of people living with HIV in 2005: Total 40.3 million

Women 17.5 millionChildren 2.3 million

People newly infected with HIV in 2005: Total 4.9 millionChildren 0.7 million

AIDS deaths in 2005: Total 3.1 millionChildren (<15) 0.57 million

Page 3: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

• In every global region the number of people living with HIV is rising.

• Steepest rises have been in East Asia, Central Asia and Eastern Europe where there has been a 9-fold increase in the last decade.

• But the situation is most serious in sub-Saharan Africa.

The World Bank identifies three types of HIV/AIDS epidemic:

NASCENT EPIDEMICAn HIV epidemic in a country in which less than 5% of individuals in high-risk groups are infected.

CONCENTRATED EPIDEMICAn HIV epidemic in a country in which 5% or more of individuals in high-risk groups, but less than 5% of women attending urban ante-natal clinics are infected.

GENERALISED EPIDEMICAn HIV epidemic in a country where more than 5% of individuals in high-risk groups as well as women attending urban ante-natal clinics are infected.

(World Bank, 1997, 87)• It is easier to control a nascent epidemic than a generalised one.

SUB-SAHARAN AFRICA• Sub-Saharan Africa, home to 10% of the world’s population has

over 60% of global cases of HIV.• Region is home to 25.8 million people living with HIV.• In 2005 there were 3.2 million new infections and 2.4 million

deaths from AIDS.• It is home to over 75% of all women globally living with HIV.

• In sub-Saharan Africa adult HIV prevalence has been stable in recent years at about 7.2%.

‘But stabilisation does not necessarily mean the epidemic is slowing. On the contrary, it can disguise the worst phases of an epidemic – when roughly equal numbers of people are being newly infected with HIV and are dying of AIDS.’ (UNAIDS, 2004)

Page 10: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

• Southern Africa accounts for about 30% of global cases of HIV/AIDS, yet this region is home to only 2% of the world’s population

• South Africa has the highest number of HIV/AIDS cases of any country, the figure exceeds 5 million people.

• Three countries have adult prevalence rates exceeding 30%:

• According to the UNAIDS 2003 report ‘The epidemic in sub-Saharan Africa remains rampant.’

• ‘The AIDS epidemics coursing through this region are highly varied – both between and within sub-regions. It is therefore inaccurate to speak of a single, “African” epidemic.’ (UNAIDS, 2004)

Page 12: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

A generalised epidemic causing demographic devastation

• The main transmission route of the disease in sub-Saharan Africa is unsafe heterosexual intercourse.

• The peak age of AIDS cases in the region are:Males 25-34 years oldFemales 20-29 years old

• More women (60%) than men are infected. • Recent studies show that on average 36 young

women (15-24 years) are living with HIV for every 10 young men.

• In 2005 over 0.5 million children were infected with HIV as a result of mother-to-child transmission.

Page 13: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

• The result has been the loss of a whole generation of young adults.

• They leave over 8 million orphans, some estimates put it at 12 million.

Page 14: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

‘The rapid spread of HIV in sub-Saharan Africa is one of the greatest failures in the history of public health.’ (Potts & Walsh, 2003, 1389)

Responses to the Pandemic

• Period 1: Up to mid 1990s: Lots of words…Characterised by Health Belief Model [a medical problem]

• Period 2: Mid 1990s to 2000: Not much action…Characterised by Primary Behaviour Change (informed by Health Belief Model) [a behavioural problem]

• Period 3: 2000 to date: Better late than never…Period of paradigm ‘drift’, recognition that social, community and structural factors are important, but biomedical and behavioural approaches still dominant [a development issue]

Background

• New disease

• No cure

• High cost of treatment

• Limited resources

• Denial and stigma

Page 18: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

Response

Health Belief Model

Based on the assumption that behaviour is shaped by the conscious decisions of rational individuals.

• Response very much medically and epidemiologically driven.

• Education and knowledge are regarded as ‘the key to effective prevention’ (UNESCO, 2005, 6)

Biomedical and health belief response to HIV/AIDS epidemics

Page 20: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

But infections continued to rise…questions asked…

• Appropriateness for sexual behaviour

• A Western approach

• Onus on the individual

• No understanding of the risk taking environment

Page 21: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

Period 2: Not much action…

• Period mid 1990s to 20001996UNAIDS set up

Multi-sectoral approach

Page 22: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

Background

• Increase in HIV infection and deaths from AIDS

• Epidemic evolves

• High cost of ARV

• Few resources

• Knowledge increasing

• Low useage of condoms

Page 23: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

Response

Primary Behaviour Change

Assumes that human beings are rational and key behaviours are under individual control.

• Stresses: abstinence, reducing number of partners, using condoms• ABC approach• ‘International responses to HIV and AIDS have changed from a

narrow health sector approach to a multi-sectoral focus.’ (SIPPA, 2005, 11)

But infections continued to rise…questions asked…

• Why are people still continuing to take risks

• Research showing that individual agency is constrained by social, economic and structural factors, such as poverty, mobility and migration patterns and gender inequality (Parker, 2000).

Price of ARV therapy in Uganda(UNAIDS, 2005)

Page 31: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

• In 2003 UNAIDS committed itself to providing ARV to 3 million HIV suffers in the poorest countries by 2005.

• According to UNAIDS the campaign is ‘the declaration of an emergency.’

‘3 by 5’ Campaign

Page 32: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

• In December 2003 South Africa announced it would make available free HAART treatment to all citizens who were HIV+.

• Uganda has pledged to give HAART to all HIV+people from January 2004 starting with pregnant women.

Page 33: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

• In Uganda ARV therapy is available to 40% of those in need, in Botswana and Namibia the coverage is 25%. In a further 13 countries coverage is 10%.

• At the end of 2004, 310,000 people were receiving ARV in the region and by June 2005 this had reached 500,000.

• By December 2005 810,000 people (17%) of those needing ARV were receiving it.

• According to UNAIDS US$3.8 billion is needed in 2005 to achieve the target, yet only US$1.55 billion has been donated.

Page 36: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

ARV is not a cure

• It can prolong the life of an HIV suffer and provide a reasonable quality of life, enabling suffers to work and care for their families.

• By reducing the viral load in the genital tract the spread of the disease might be slowed.

• But there are issues of patient compliance especially in deprived communities.

• Fears of drug resistant strains of the virus developing.

Yet promises are not always translated into action (UNAIDS,

Page 40: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

Some questions…and a paradigm drift…

• ARVS are welcome but might divert resources from prevention programmes and could result in complacency

• Infection and death from HIV and AIDS continue to rise.

• Despite good levels of knowledge people continue to engage in risky sexual behaviour

Page 41: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

Some countries in East Africa, such as Ethiopia, Kenya, Uganda and Zimbabwe show signs of decline in infection levels.

• The steepest drop has been in Uganda, where national prevalence rates have fallen from 13% in early 1990s to 4.1% at end of 2003. This it is suggested has been the result of behavioural change, in particular an increased use of condoms.

• But it is too early to claim that these declines herald a definitive reversal of the epidemic in these countries, recent research suggests infections are once again increasing.

• But ‘East Africa continues to provide the most hopeful indications that serious AIDS epidemics can be reversed.’ (UNAIDS, 2005, 25)

Page 42: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

• People need knowledge to enable them to be able to make choices about their life styles.

• But this alone can’t guarantee behavioural change.

• There are many intervening factors that prevent individuals adopting safer behaviour.

Page 43: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

Paradigm drift

• ‘Evidence is mounting that global models of HIV/AIDS prevention, designed by Western experts, have been largely ineffective in Africa.’ (Green, 2003) He continues by saying AIDS is a ‘behavioural problem with behavioural solutions.’ but this is questioned by Farmer. He states that it is becoming clear that ‘AIDS is also surely, a social problem with social solutions.’ (Farmer, 2003).

Page 44: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

‘…a generalised HIV/AIDS epidemic does not just happen. There are social, economic and cultural reasons why such events occur.’ ‘In certain circumstances risk environments develop and these increase susceptibility.’ (Barnett & Whiteside, 2003, 96 & 97)

Hemrich & Topouzis (2000) state that AIDS is rooted in problems of poverty, food and livelihood insecurity, socio-cultural inequalities and poor support services and infrastructure.

Page 45: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

Campbell ( 2003) argues that there is a need to focus on the psycho-social and community level determinants of sexuality. We need to pay attention to the social change that needs to take place to support the likelihood of healthier sexual behaviour. She states that ‘Sexual behaviour, and the possibility of sexual behavioural change, are determined by an interlocking series of multi-level processes, ranging from the intra-psychological to the macro-social.’ (p. 183)

Page 46: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

The wider picture of the factors that facilitate HIV transmission

Page 47: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

Too Little…Too Late…

• ‘AIDS responses have grown and improved considerably over the past decade. But they still do not match the scale or the pace of a steadily worsening epidemic.’ (UNAIDS, 2005,5)

• ‘…the AIDS epidemic continues to outstrip global efforts to contain it.’ (UNAIDS, 2005,6)

• ‘…responses to the epidemic came too late and were not commensurate to the magnitude and urgency of the challenge.’ (UNESCO, 2005, 5)

Page 48: Too little too late: responses to the HIV/AIDS pandemic Professor Hazel Barrett Geography Department Coventry University

• ‘Bringing AIDS under control will require tackling with greater resolve the underlying factors that fuel these epidemics – including societal inequalities and injustices.’ (UNAIDS, 2005, 5)

• For Basu (2004) AIDS ‘is a symptom as much as it is a disease.’ (p. 158)
