Introduction:

Health matters. When you are healthy you are able to use your energy to work and support people around you. When you are sick your energy falls and it is a struggle to get through a day. 
Poor people are more likely not to be healthy, they do not have the resources to buy healthy food, they have to go for what is the cheapest products on the market, or what little their small plot of land yields. Most of the time those choices are not good for health. 
Many places in the world water is not for free, especially clean, treated water. Poor people therefore use water from rivers and lakes that is not safe to drink. Water can be cleaned when it is boiled, or when it is treated with ultra-violet light from the sun. To boil water firewood or gas are needed, and if resources are scarce many chose to boil the rice that you cannot eat without. 
Many diseases can be avoided if you have knowledge. Big killer diseases such as HIV/AIDS, tuberculosis, and malaria, are often avoidable and treatable, but they kill millions of people every year, including many small children. 
&nbsp; 
New HIV/AIDS infections occur mainly in Sub-Saharan Africa, 72% of all new infections were registered here in 2008. 
A positive development is that more and more people who are HIV-positive receive anti-retroviral drugs. In Sub-Saharan Africa, 14% of the HIV-positive persons received it in 2005, but 43% in 2008. These drugs greatly improve the life of the infected and reduce risks of transmission. 
Tuberculosis is very slowly on decline, only 1% less persons get TB each year. More than 2 billon people live with the TB bacilli, the microbes that cause TB, and most of them never get sick from the disease. TB is a poverty disease, if people have weakened immune system the microbes can attack. This often happens to people who are HIV+. In 2009, 9.4 million people got sick from TB. 1.7 million people died from the disease, 380,000 of them were HIV+.&nbsp; 
Many organizations and governments assist in educating about malaria and providing insecticide-treated bed nets, especially for children under 5. In Zambia, 1% of the children under 5 used the nets in 2000, but 41% in 2008. In Guinea Bissau 7% of the nets were used in 2000, but 39% in 2008. If all children under 5 use the treated nets, cases of death will be dramatically reduced, and if all people use the nets there would be a great reduction in new cases of malaria. Yearly around 250 million people get the disease, and almost 1 million die from it, mostly in countries in the southern hemisphere.&nbsp; 
&nbsp; 
With more education, materials for prevention and treatment in health centers, outreach programs and community actions, and different types of clubs, such as farmer&rsquo;s clubs, women&rsquo;s clubs, income generating clubs, youth clubs and special efforts to reach out to poor people, much can improve. When people are healthy they are more productive and able to find solutions to improve their own situation as well as the situation of their neighbors.
