There were 320,000 Hiding Virus in Animals Mammals

Kompas.com-Start of Ebola, SARS, West Nile, to HIV, that all were a contagious disease that endemic in humans and animal origin. In mammals, there were at least 320.000 known viruses that the majority have not unknown.
The scientists said, identifying and collecting the data on a hiding to pathogens infectious to mammals before humans can prevent the occurrence of disease outbreaks. “Right now we know about the new virus in what been transmitted to humans or animals and are known as a disease. Many virus in wild animals and could potentially be a source of diseases, “said lead researcher was Simon Anthony of the Center for Infection and Immunity at Columbia University Mailman School of Public Health.
Anthony and his team estimate the diversity of viruses by examining virus carried by bats called flying foxes and live in the forest in Bangladesh. Bat was the largest flying mammal with a wingspan reaching 1.8 meters. The researchers recognize this species as a source of Nipah virus which can cause deadly brain fever.
Virus was first infected humans in 1990 and according to the World Health Organization has led to the collapse of dozens of victims across South Asia. Teams of researchers took a sample of the throat swabs, faeces and urine from 1.897 live bat and healthy. Then the animals were released back in the nature. Of laboratory examination was found 55 types of the virus in 9 families virus and only 5 of them are recognizable.
Estimated total amount of virus in flying foxes reach 58 virus. If every 5.485 species of mammals were known to carry 58 unique virus, then there were about 320.000 of virus in the wild. Upon research, scientists plan to conduct further studies on primate species in Bangladesh and 6 species of bats in Mexico to determine viral diversity.
The study would require a very large fund, but they assess the amount was small compared with the costs to be incurred in the event of a disease outbreak. Funds for surveillance, sampling, and laboratory studies to bats that needed funds around 1.2 million U.S dollars. Based on that data, estimated to cost 6.3 billion U.S dollars to research on primates.
For comparison, at the time of the SARS outbreak in Asia in 2002, the economic impact of this outbreak reached 16 billion U.S dollars. “Our research did not guarantee will prevent another outbreak like SARS, but by studying virus diversity globally we can to mitigate outbreaks by facilitating data collection and rapid diagnostic tests, “said Anthony.
