Dengue , anger , malaria or leptospirosis are some of the so-called "diseases subject to national and international epidemiological surveillance", when they occur floods and landslides. A few weeks ago, in our country, the health contingency that generated the overflow of Coatzacoalcos River and the strong rainy season in the Mexican southeast, went around the world. It was not for nothing: at human and material losses , the gastrointestinal diseases and the disorders of tracks respiratory of thousands of people. The problem is exacerbated when the marshy waters and black waters are mixed, putting human health at greater risk. To avoid the known outbreaks of epidemics and dengue, the authorities need to launch programs of timely medical attention and, sometimes, vaccination campaigns; implement tasks such as sweeping the streets, fumigations and abatizations (application of larvicides to prevent the proliferation of the malaria mosquito).
These diseases can trigger a epidemic of major consequences, if they are not attended and controlled immediately. Dengue, for example, is very common in tropical regions Y subtropical , particularly in urban and semi-urban areas, and the only way to prevent it is through fumigation and control of mosquitoes of the species Aedes aegypti who transmit it; Dengue causes a high fever that disables people with severe headaches and eyes, as well as muscles, bones and joints. In the case of malaria, it is transmitted by the infectious bite of mosquito anopheles that grows in shallow fresh water (such as puddles, rice fields or animal tracks) and itches at night; rains, temperature and humidity favor the abundance and survival of mosquitoes and, in the case of children, a malaria not timely attended, It can be deadly . Cholera is an acute intestinal infection, characterized by abundant diarrhea, vomiting and dehydration; it is transmitted by contamination of water and food and is produced by a highly mobile bacillus. Finally, leptospirosis is an infectious and serious disease that affects the liver and other organs; This condition is transmitted by eating food or liquid contaminated with the urine of the animals carrying the bacteria, through small wounds or conjunctivae and after bathing in contaminated water. So, in the face of any symptom of discomfort, it is imperative togo to the health center closest.
