  2. AIDS / HIV

  3. What is AIDS? • Acquired Immunodeficiency Syndrome • Destructs body’s immune system • Aids is caused by the virus HIV • HIV is Human Immunodeficiency Virus • Most severe manifestation of HIV

  4. Symptoms • Flu-like symptoms • No symptoms • Fever, Fatigue, Diarrhea, Skin Rashes, Night Sweats, Loss of appetite • Other possible affects include • Opportunistic infections, cancers, pneumonia, and tuberculosis

  5. The spread It can be spread in 1 of 4 ways • Exchange of bodily fluids during sex • Contaminated needles in drug use • Contaminated blood transfusions • From mother to child during pregnancy

  6. MEDC’s • In MEDC’s in the early days it only spread among gay communities and in prostitutes. The heterosexual population was unconcerned and many called it the gay plague. Now it is confined to mostly the gay communities of Europe and the USA.

  7. LEDC’s • Meanwhile in LEDC’s the disease was being spread in heterosexual communities. This was not known to MEDC’s for a long time.

  8. Eastern Europe & Central Asia 1.6 million [990 000 – 2.3 million] Western & Central Europe 720 000 [570 000 – 890 000] North America 1.2 million [650 000 – 1.8 million] East Asia 870 000 [440 000 – 1.4 million] North Africa & Middle East 510 000 [230 000 – 1.4 million] Caribbean 300 000 [200 000 – 510 000] South & South-East Asia 7.4 million [4.5 – 11.0 million] Sub-Saharan Africa 25.8 million [23.8 – 28.9 million] Latin America 1.8 million [1.4 – 2.4 million] Oceania 74 000 [45 000 – 120 000] Total: 40.3 (36.7 – 45.3) million It is growing in ALL regions of the world Adults and children estimated to be living with HIV as of end 2005

  9. Swaziland 38.8% Botswana 37.3 Lesotho 28.9 Zimbabwe 24.6 S. Africa 21.5 Namibia 21.3 Zambia 16.5 Malawi 14.2 CAR 13.5 Mozambique 12.2 S. Africa 5,300,000 India 5,100,000 Nigeria 3,600,000 Zimbabwe 1,800,000 Tanzania 1,600,000 Ethiopia 1,500,000 Mozambique1,300,000 Kenya 1,200,000 DRC 1,100,000 USA 950,000 Country Level

  10. Case study Zambia • 1 in 7 adults infected • Life expectancy is down to 39 years as a result • 200 new infections every day • Disease has been present there since 1984 but was kept under wraps by the government until the late 1990’s • Most of the spread is due to heterosexual intercourse

  11. The role of women in society • Zambian women have an extremely low status in society. • Women are taught not to refuse sex, insist on condom use or demand that their partners be faithful. • Women will often also be sexually active at a very young age with partners many years older than them who may have already had several sexual partners

  12. Cultural issues • Some practices and beliefs have a direct effect on the transmission of HIV. • For instance, it is believed that men can cure sexually transmitted diseases by having sex with a virgin. 15% of girls in Zambia admit to have had sex forced on them at some point • Family and tribal elders are also expected to initiate young girls into womanhood, through sexual intercourse.

  13. Economic problems • The biggest issue is of course the vast healthcare budge which Zambia must spend on treating the infected. • There is also the problem of loss of workers. In 2002 Zambia faced famine as so many agricultural workers were killed that the crops could not be effectively harvested.

  14. An improving problem? - NO

  15. Why is the problem not being solved? • People are reluctant to admit being infected as they might suffer prejudice from employers and the community • Drugs are not affordable • Many people do not know they have it • Many of the churches and government officials refuse to encourage people to use condoms, advocating abstinence instead. They suggest that using condoms is a sign of weak morals. • Condoms are expensive and very few are given away free from clinics etc.

  16. Homework • Due Thursday 1st March • May have some class time • Deliver a presentation on a pandemic • Include information on how your pandemic started, how it spread and what the impact was • Options – black death, spanish flu, bird flu, swine flu, SARS • Can work in pairs
