(Fort Collins-AP) -- Scientists in a fenced-off laboratory in Fort Collins are working hard to tame the West Nile virus.
The lab near the foothills is home of the Center for Disease Control's vector-borne infectious disease division.
Nearly 30 researchers have traveled to Louisiana, the current focus of America's worst outbreak. The ones remaining in Colorado are putting in 11-hour days as they try to learn more about the virus.
The strain being seen this summer is faster and stronger than past varieties. It's been found in more tan 115 bird species, nine kinds of mammals and 30 types of mosquitos.
