article imageInfectious diseases on the rise globally

By Fatik Baran Mandal     Dec 3, 2010 in Science
Since 1980, more than 35 new human infectious diseases have emerged. Of 1415 human pathogens, 61 percent are zoonotic, and multiple host pathogens. Animal-related disease outbreaks have resulted in hundreds of billions of dollars of economic damage.
The alarming situation of wildlife trade, coupled with modern transportation systems historically increases the movement and cross-species transmission potential of a number of pathogens. Live animals comprising about 40,000 primates, 4 million birds, 6.4 million reptiles and 350 million tropical fish are traded globally each year. About 90,000 mammals are traded per year from a single market in North Sulawesi, Indonesia. About 7.7 million birds belonging to 276 species were reported to be sold from one market in Thailand during 25 weekends. Of 36,537 birds observed in 4 markets of Bangkok, 37% were native, while 63% were non-native species.
Consumption of wild animal meat in central Asia alone is more than one billion kg per year.
Since 1980, more than 35 new human infectious diseases have emerged. SARS-associated Coranavirus is suggested to be associated with the international trade of small carnivore. Of 1,415 human pathogens, 61% are zoonotic, and multiple host pathogens. Seventy-seven percent pathogens of livestock inhabit other hosts.
Animal-related disease outbreaks have resulted hundreds of billions of dollars of economic damage globally. Outbreak of emerging and reemerging disease throughout the world since the mid 1990s has caused the loss of the world economies $80 billion.
