During recent years, quite a large number of geographers have directed their studies to a comprehensive presentation of the health situation of various regions and countries and the nosological principles in describing the endemic and pandemic foci of disease diffusion patterns have been applied. But inspite of these epidemiological studies and the inventions of several curative and therapeutic measures, the disease incidences have not shown a downward trend neither on a regional nor on a global scale. This speaks about the lack of preventive measures and the total paucity of dissemination of knowledge about health and hygiene in the common people which is so essential to mitigate the miseries of the people on account of ill-health.
