Human Health and Environment - Assignment ExampleIn 1793, much than 5000 Americans died as a result of the yellow fever epidemic which started in Philadelphia. (Murphy, J., 2003) There are an estimated 200,000 cases of yellow fever, causing 30,000 deaths, worldwide each year. (Yellow Fever, 2009) On the opposite hand, The World Health Organizations Guidelines for the treatment of malaria (2010) has reported an estimated 863,000 deaths in 2008 due to malaria. Still another similar factor yellow fever and malaria touch is that they almost have the same symptoms. Both diseases make the victim feel feverish and body ache. Conversely, yellow fever can be different from malaria, too. Firstly, where malaria has a cure thanks to the medicine quinine (Agosta, W., 1997), there is only a vaccine for yellow fever and a cure dependent on the resulting illness manifested by the patient. (Hayes, J.J., 1858) The said vaccine was discovered by Max Theiler in 1937. (Monath, T., 2010) Secondly, the incubation fever for yellow fever is only for 3-4 days, malaria victims only show signs of the symptoms after 7 to 30 days. (WHO, 2010) Last but not the least, while yellow fever has mostly affected people in Africa and Latin America, deaths and cases of malaria are in sub-Saharan Africa. (WHO, 2010) 1.b) A mosquitos bite causes malaria and yellow fever. Since North America goes through the winter season, egg production stops and there is no drive for the womanly mosquito to take blood meals. (Humphreys, M., 2001) Because there is no need to bite humans for blood, these diseases are not threats in North America. 1.c.) No single pastoral in sub-Saharan African has shown a substantial decline in malaria, according to WHOs Africa Malaria Report 2004 (Crowe, S., 2003) This can be attributed to two things Africa is a tropical country and a poor one at that. Tropical countries only have two seasons sunny and rainy. Inasmuch, the climate in tropical countries can be warm, humid or cool.
