Typhoid fever is a serious and sometimes life-threatening infection that primarily affects people in third world countries, where clean water and other sanitation are difficult to come by. People usually contract typhoid fever by drinking water that contains infected feces. People who carry the disease can also transmit the disease directly to others. For example, having physical contact with another person can transmit the disease to that person. Bathing in water that contains S. Typhi bacteria can cause the bacteria to enter your body. Areas where there are not enough toilets or wastewater treatment systems are more likely to carry the infection. When feces contaminates water, the bacteria can grow rapidly, which poses a threat to people where Salmonella typhi is prevalent. Water treatment such as pur pack, rescue straw, biosand filter and solar cooker can help prevent people from becoming contaminated with parasites. For these reasons, the disease is common in areas with poor sanitation and inadequate water treatment. One of the hardest hit places in all of Africa is Nigeria. Typhoid fever has consequential effects on both the body and mind that can kill someone if left untreated. The symptoms and diagnosis of typhoid fever are as follows. People who suffer from typhoid fever usually have a fever between 103° and 104° F. The patient may also feel weak, have a headache, and loss of appetite. A rarely seen symptom is a rash that resembles pink-colored spots. Abdominal tenderness, agitation, hallucinations, chills, confusion, attention deficit, fluctuating mood, delirium, bloody stools, nosebleeds, severe fatigue, feeling sluggish and sluggish, lethargy, and weakness can and will occur if the disease is not treated.

Another contributing factor is the doctor-patient ratio which is three doctors per 10,000 people. While the United States has one doctor for every 390 people. This equates to a change of 2,943 people per doctor. The reason why much of Nigeria is prone to typhoid fever is because of the low GDP per capita which is a staggering 1,555. Since most Nigerians live on a dollar a day, people cannot afford water treatment. Since a solar heater can be made from simple materials such as cardboard boxes and aluminum foil, one can be made for about $15. Since the cardboard box is square, all four sides can be cut away from each other so that all the light reflects into the water in the center of the box.
