The dramatic spread of deadly diseases around the world collected by an international team of scientists. According to scientists, the greatest threat to the people in the underdeveloped countries infections are transmitted from wild animals, and in development - flash pathogenic viruses that are resistant to antibiotics, and new diseases caused by the use of chemically processed foods. Experts note at Columbia University and the Center for International Earth Science Information, that the old disease moved rapidly into new regions and cause epidemics. Thus, the AIDS pandemic, which probably costs from human contact with chimps, which are more than 65 million infections and the recent SARS outbreak, vectors, the Chinese bats, led the health system in the world $ 100 billion. The researchers analyzed 335 diseases that have appeared in the years 1940-2004, and compared with the results of the survey population density and biodiversity of wildlife on the planet. It was found that after 50 years, was deadly disease in the world four times. About 60% of the virus transmitted to humans from animals. "Hot spots" of infectious epidemics experts believe Saharan Africa, India and China to develop less harmful diseases in Europe and South America. According to representatives of the Zoological Society of London, such developments are related primarily to the increase in population density and imperfect method of protecting the human body against disease-causing bacteria. If not urgently undertake the development of potential new treatment and prevention of diseases, say biologists, not soon the extent of pathogenic viral variants can be controlled. The second global problem, in their view, is the resistance of microorganisms to antibiotics to cure due to which 20% of the most common diseases difficult. With the high rate of lethal bacteria on human health in many rich countries, and modern medicine is not able to prevent the disease.
