HIV attacks the cells that fight disease, damaging the immune system. People who have the virus are known as HIV-positive.
People who are HIV-positive don't get sick immediately, but the virus slowly wears down the immune system, until the body can no longer fight disease.
Once the immune system is damaged, HIV-positive people develop a group of diseases that are known as AIDS .

A set of diseases that people get once their immune system is damaged by HIV. What is HIV and AIDS?
Herpes (cold sores, genital herpes)
Septicaemia (infection of the blood)
Recurring fungal infections of the skin, mouth and throat
Other skin diseases
Cancers such as Kaposi sarcoma
Chronic diarrhoea with weight loss ("slim disease")

- mother to child transmission
- dirty medical equipment
especially poorly equipped hospitals in developing countries
- drug users sharing needles
especially in Eastern Europe, South and
- unprotected heterosexual sex
- blood products
if not screened
- unprotected male-to-male sex
especially in developed countries like New Zealand, but world-wide, only 5% of those who have died from AIDS were men who have sex with men.

Over 20% of the agriculture workforce in Botswana, Mozambique, Namibia and Zimbabwe will be lost to AIDS by 2020.
In northern Zambia, female-headed households caring for people living with HIV also supported on average 3.6 orphans each. Providing enough food for the household is difficult.

It is estimated that on average, HIV-related care can absorb one- third of a household’s monthly income.
In sub-Saharan Africa children miss out on an education because income is used to pay for treatment instead of school fees.
Tanzania needs around 45,000 additional teachers to make up for those who died or left the system because of AIDS.
Botswana lost 17% of its healthcare workforce due to AIDS between 1999 and 2005.

HIV and AIDS: strategies Slide 18 Strategies for HIV and AIDS 1. Prevention Education and behaviour change
Tackle stigma so people can talk openly about HIV and AIDS
Education on how HIV is spread and avoiding high-risk behaviours (ABC)
Addressing barriers to behaviour change: gender relations, economic barriers, cultural practices
Focus on high risk groups, like truck drivers, migrant workers and sex workers
Focus on pregnant & breast-feeding mothers
Education on prevention strategies
Healthcare during and after pregnancy
Mother-to-child transmission Trained in AIDS-prevention curriculum, teacher Ng’ona Robert runs a school assembly with the help of peer educators. RAPIDS results Reached 62,752 youth with AIDS-prevention methods.
Caregiver Charity bathes Patrick’s sores. Before she leaves she encourages him and cooks a meal. 2. Care for the sick HIV and AIDS: strategies
Counselling and emotional support
Education about living with HIV
Advocating for wider availability of drug treatments
Preventing other infections through healthcare, clean water, and sanitation
Providing practical support such as food, blankets, sheets
Training and support for care-givers
Home-based care and counselling, especially where hospital beds are scarce
Slide 19 RAPIDS results Includes: HIV counselling and testing for 16,894 people; home-based care to 43,868; helping 24,939 people adhere to ARV treatment.
HIV and AIDS: strategies Slide 20 RAPIDS results About 228,000 orphans and vulnerable children assisted. Now about 90% are in school. Three years ago only 30% were in school. 3. Care for those left behind
Meeting the immediate and long term needs of orphans and elderly caregivers in the absence of mums and dads.
Counselling and support for children who have lost their parents
Helping orphans or elderly guardians to strengthen their income and food supply
Making sure orphans have access to education
Improving living conditions
HIV+ orphan Enouch, visits with his caregiver Roderick.
She thought things could not get worse, and then she got sick. Most days she was confined to bed. She was dying. Agnus sought the help of a World Vision-trained caregiver. She was persuaded to get an HIV test, which turned out positive. Agnus, 42, once had a husband, five sisters and a brother. They all died of AIDS leaving her to care for their children. Agnus, a widow, is now responsible for 13 children. Her caregiver reassured Agnus, saying there were plenty of others who were HIV-positive but through antiretroviral therapy (ARV) were getting well. Agnus began taking ARVs. Within weeks she felt better and was able to start work again. Slide 21 Agnus - Zambia
Slide 22 Nancy – Papua New Guinea Nancy received counselling at a World Vision drop-in-centre. Nancy said, “It helped me to think and live a positive life. Before this I thought everything was meaningless knowing that I was going to die. Now, most days I forget that I am HIV positive and this helps me to remain healthy and strong. I enjoy my life like any other normal person.” Nancy (not her real name), 45, found out she was HIV positive when she went for a blood test without her husband knowing about it. She knew straight away that she got the virus from her husband. She said, “The thought of walking around with the deadly virus in my body is very frightening and this is causing me to have sleepless nights. I worry about my 12-year-old daughter, whether I will be around to see her grow up.”
My son Pirirani is four. He has been ill with diarrhoea, stomach pains, weight loss, a cough and fever for more than three years. My baby Davis is 13 months old, and he is wasting away. I also am unwell, and my wife Celina. And I look after my parents, who are old, and two orphans. I had a lot of pigs, but I would sell anything to save the life of my children. I always thought I would live a happy life with my beautiful wife, working hard on my land for my children’s future. I thought we would own cattle and I would have a pleasant home. But the story has come out differently to my dreams because of this sickness. We have no cash, but I need 400 kwacha (NZ$13) for the next round of medicine for the children. A chicken sells for 150 kwacha. Slide 23 Vincent - Malawi
And my staff are not safe. If you stick yourself with a needle – and that’s a common thing – there is no chance of getting anti-retroviral treatment if you get HIV. So you find you don’t always want to know, and most staff don’t get tested after a needle-stick. In most cases we strongly suspect AIDS based on the symptoms, but we don’t always carry out tests because of the lack of resources and the workload. You should counsel people before and after the test, and we don’t have enough staff for that. It’s desperate if you really look at it. We have 240 beds in this hospital, and we have more than 300 patients, with people sleeping on the floor. The overcrowding is very definitely related to HIV. AIDS is making the related problem of tuberculosis very serious and complicated. Frankly, sometimes you give a treatment and you just pray that it will work. Slide 24 Ntcheu Hospital - Malawi
Sophy is often kicked out of children's groups when she tries to play with them. The shame and the pain inside Sophy have completely changed her. She is quiet and rarely laughs. This is my great-grandniece, Sophy. She is three years old. First her father and then her mother died of AIDS. When Sophy’s mother started to get sick she and her three children came to live with my sister and I. My name is Eng. I am 79 years old. Sophy has HIV from her mother. She has a skin infection on her head. Wherever she goes, she wears this hat to protect her head from flies and to hide her infection from other children. Most children don’t like Sophy much because of her infection and the bad smell from her body. Slide 25 Sophy - Cambodia
I know that men my age are the ones getting HIV. With this killer disease that is affecting our country, I try and keep myself safe. Zione too, she is not safe. She is too young to date, to go out with boys. I’m doing my best to help her and look after her. I work at anything I can, for 50 kwacha a day to buy enough food (about NZ$1.20). Sometimes we have two meals a day and sometimes only one. I have gone as far as I can with free education. I did well in school, and I would like to continue. My English is very strong, and I would like to be a mechanic. But I can't afford my school fees if I am to look after my sister. Our mother died a year ago, she was sick for a long time. I left school right away to look after Zione. She is 13 and she wants to be a nurse. If she continues at school, and she wants to, she could start nursing training after she finishes Form 4.
