HEALTH DURING INDUSTRIAL REVOLUTION Malaria Malaria disease is transmitted via a bite from an infected female mosquito, which its saliva introduces into a person's circulatory system. The infection develops in two phases: one the liver and the other involves red blood cells, Malaria causes symptoms that typically include fever and headache, which in severe cases can progress to coma or death. The disease is widespread in tropical and subtropical regions. The World Health Organization has estimated there were 219 million documented cases of malaria. It is commonly associated with poverty and may also be a major hindrance to economic development. No effective vaccine exists, although efforts to develop one are ongoing. Several medications are available to prevent malaria in travelers to malaria-endemic countries. Snail Fever Snail fever is another example of the diseases that can be caused by the way we alter the environment. People don’t take care of their actions and how they may affect the environment as long as it helps their objective. The Diama Dam in Senegal was made by people to make the irrigation of rice fields easier. This method worked for the rice fields but it affected the environment. The Dam blocked the salt water entering the river and that way freshwater snails out competed the saltwater snails. The freshwater snails have schistosomes that cause snail fever. The disease rate increased. The disease is introduced in human bodies by them bathing in the river and doing their laundry in the contaminated water. Lyme Trends are not limited to developing countries. In 2003 The Rutgers University, Bard College and the Cary Institute of Ecosystem Studies make studies and they found and showed that they were high incidences of Lyme disease in the suborns. How do people can get to that? Well they get the disease from blacklegged tick bites, and the ticks live in the fur of whitefooted mice. As the suborns move away and expand, the predator population decrease, but the ticks multiply and so the mice. Many cases are not isolated. Every Environment delivers ecosystems services. It is difficult to predict what would happen to an ecosystem if we interact with it. We have already some diseases from the past that can continue to coexist. Page 10
