WASHINGTON (CNN) -- Missing vials of a potentially dangerous virus have prompted an Army investigation into the disappearance from a lab in Maryland.
The Army's Criminal Investigation Command agents have been visiting Fort Detrick in Frederick, Maryland, to investigate the disappearance of the vials. Christopher Grey, spokesman for the command, said this latest investigation has found "no evidence of criminal activity."
The vials contained samples of Venezuelan Equine Encephalitis, a virus that sickens horses and can be spread to humans by mosquitoes. In 97 percent of cases, humans with the virus suffer flu-like symptoms, but it can be deadly in about 1 out of 100 cases, according to Caree Vander Linden, a spokeswoman for the Army's Medical Research Institute of Infectious Diseases. There is an effective vaccine for the disease and there hasn't been an outbreak in the United States since 1971.
Remember this story the day before when all the polo horses from Venezuela died at the Wellington polo club in Florida?
