Hans Rosling 3, Insights on HIV, in stunning data visuals (script)
Summary
HIV is a virus that gradually attacks the immune system, which is our body’s natural defence against illness. If a person becomes infected with HIV, they will find it harder to fight off infections and diseases. The virus destroys a type of white blood cell called a T-helper cell and makes copies of itself inside them. The most common way for someone to become infected with HIV is by having sex without a condom.  You can also risk infection by using infected needles.
HIV spread in 1983 in the world. Many people have a prejudice that HIV spread in only Africa. This is wrong thoughts. Although there are some countries which the rate that HIV infected people is the highest in the world in Africa, there are countries which are the same rate as the United States. Brazil, Iran, India and Southeast Asia are higher rate but there is one part that is the highest rate in Africa.
Even if you'll be infected with AIDS from HIV, you don't die of AIDS if you're treated properly for ten or twenty years. However, its treatment costs too expensive for poor people to continue caring. They will die. The key to ending the epidemic is to teach protecting this disease more.
We'd put money down not to continue caring but we wouldn't understand where and why to spread. We have to use not only heart and money but the brain more to solve this problem. First, you must see true data. This is the stunning data he made free of charge and his explanation that he showed his wallet was more remarkable.
