cord-256615-gvq8uyfk	Rosenberg, Ronald	Detecting the emergence of novel, zoonotic viruses pathogenic to humans	2014-11-22		.txt	text/plain	6688	306	45	RNA viruses, with their high potential for mutation and epidemic spread, are the most common class of pathogens found as new causes of human illness. An analysis of virus discovery indicates that the small number of novel viruses discovered annually is an artifact of inadequate surveillance in tropical and subtropical countries, where even established endemic pathogens are often misdiagnosed. Many of the emerging viruses of the future are already infecting humans but remain to be uncovered by a strategy of disease surveillance in selected populations. Despite the differences in clinical presentation and geographical location, these three pathogens share three characteristics: all were unknown before found infecting humans, all are RNA viruses, and all have proven or putative non-human, animal sources. A single subtropical bat species hardly represents all mammal species and indeed many viruses are known to infect more than one species; they tested for only 9 of the 25 virus families pathogenic to humans.	./cache/cord-256615-gvq8uyfk.txt	./txt/cord-256615-gvq8uyfk.txt
