Water-Borne Infectious Disease Outbreaks Associated with Water Scarcity and Rainfall Events

摘要: An important number of major infectious diseases are related to water. The greatest consequences for the human population faecal-oral water-borne diseases, which transmitted by ingestion causal agents that released into water through faeces. occurrence outbreaks could be affected scarcity at different degrees depending on level scarcity, density population, degree economical development, presence in area wild and farmed animals, etc. Still, least developed countries laws regulatory programmes regarding quality cope with most problems generally protect even when obliges use non-conventional resources. Weather conditions influence fate pathogens environment. Indeed rainfall favours their dissemination, natural stressors – such as temperature solar irradiation among others determine persistence. At present, heavy rain events rather than main cause failure protective measures countries. This situation is likely due an increased dissemination have survived deleterious effects stressors. Higher frequency drought followed rains, forecasted Mediterranean climate areas, will increase deficiencies watershed protection, infrastructure storm drainage. Consequently, risk contamination resources greater before. combination factors might also failures drinking treatments, subsequently disease outbreaks. A better knowledge about origin, survival transport environment a key factor predicting risks taking minimize them. Unfortunately many developing countries, consumption still very poor independently whether there or abundance Measures improve present urgently needed. These optimized considering weather microorganisms faecal origin.
