The international team of scientists has documented dramatic spread of deadly diseases in the world. Over the past 50 years, fatal disease on Earth has been four times increased. Approximately 60% of viruses formatted from animals to people.
The study by experts at the University of Colombia and the Center for International Earth Science Information Network (CIESIN, USA) reviewed 335 diseases that have emerged in the year 1940-2004, and compared the results of the review with the population density and the biological variability of wildlife on the planet.
Deadly diseases clearly divide the countries on the basis of well-being. For example, in underdeveloped countries most serious threat to their residents - a new infection, as experts see.
In developed countries, the greatest threat resistant pathogenic viruses and new diseases arising from the use of chemically processed foods.
Researchers note that old infections quickly moved into new regions and cause an epidemic. The AIDS pandemic, presumably taking its origin from contact of a person with a chimpanzee, has led to more than 65 million infections.
And recent outbreak of SARS, which were carriers of the Chinese bats, the world’s health care cost of 100 billion dollars.
āHot spotsā of infectious epidemics believed the district Sahara African countries, India and China. In less dangerous diseases develop in Europe and South America.
The risk growth trend of fatal diseases associated primarily with the growing population density and imperfect method of protecting the human body from the bacterial disease, warn experts of Zoological Society of London.
If not urgently address the possible development of new treatments and prevention of disease, biologists say, the time will be wasted. And then the scope of the pathogenic virus variants will be impossible to control. The consequences in this case would be terrible.
