A Geographical Study on Seasonal Diseaes in Mandalay City Mya Mya Than Mandalay City, an old capital lying in Central Myanmar, has favourable geographic conditions for the development of seasonal diseases. With a total population of 796,091 and a density of 19,253 persons per square mile, 0.65% to 0.77% of the population is recorded to have suffered, among the seasonal diseases, mainly from diarrhoea, Dengue Hemorrhagic Fever (DHF) and Acute Respiratory Infection (ARI) during the recent years. In this research, the researcher identifies the epidemic seasons from the geographical point of view: diarrhoea occurs mostly in the rainy season, DHF in the late rainy season, and ARI in the late rainy season to the early winter. As epidemic areas, diarrhoea prevails yearly or periodically in water-logged settlement areas and in wards of poor sanitation and human environment, DHF in those areas as well as in the slum areas, and ARI in places polluted by air indoor or in surrounding areas. Moreover, it is found that the occurrence of diarrhoea increases when temperature, rainfall, and humidity become higher. DHF cases also increase directly with the three climatic elements but the correlation is high with relative humidity and low with the other two. ARI cases increase reversely with temperature and rainfall, and directly with relative humidity. Finally, a conceived model showing the factors influencing upon seasonal diseases in Mandalay City is produced. 2012 http://hdl.handle.net/20.500.12678/0000000692 https://meral.edu.mm/records/692
