The World Health Organization on Sunday declared the end of the most recent outbreak of Ebola virus in the Democratic Republic of the Congo, the eighth in the African nation since the virus was discovered there in 1976. The Centers for Disease Control and Prevention commended the country for stopping the outbreak in less than two months. “This highlights what is possible when countries are prepared to prevent, detect and respond to disease outbreaks,” the agency said. In addition to experts from WHO and CDC, nine detectives from the DRC’s Field Epidemiology Training Program responded to the outbreak, in which four people died and four survived the disease.
