there could be at least 320,000 viruses awaiting discovery that are circulating in animals, a study suggests.

研究发现,动物间传播的至少32万种新病毒有待人们去研究。
 
researchers say that identifying these viral diseases, especially those that can spread to humans, could help to prevent future pandemics. 
 
the team estimates that this could cost more than £4bn ($6bn), but says this is a fraction of the cost of 1 with a major pandemic.
 
the research is published in the journal mbio.
 
prof ian lipkin, director of the center for infection and 2 at the university of columbia in the us, said: "what we're really talking about is defining the full range of diversity of viruses within mammals, and our intent is that as we get more information we will be able to understand the principles that 3 determinants of risks."
 
flying fox
 
nearly 70% of viruses that infect humans, such as hiv, ebola and the new middle east respiratory 4 (mers), originate in wildlife.
 
but until now, the scale of the problem has been difficult to assess.
 
to investigate, researchers in the us and bangladesh looked at a species of bat called the flying fox. 
 
this animal carries the nipah virus, which if it spreads to humans can kill. 
 
by studying 1,897 samples collected from the bats, scientists were able to assess how many other pathogens the animal carried.
 
they found nearly 60 different types of viruses, most of which had never been seen before.
 
the team then extrapolated this figure to all known mammals, and concluded there were at least 320,000 viruses that have not yet been detected.
 
the researchers said that identifying all of these would be crucial to keeping one step ahead of diseases that could become a threat to human health.
