This image was created during an investigation into an outbreak of monkeypox, which took place in the Democratic Republic of the Congo (DRC), 1996 to 1997, formerly Zaire. Pictured here, was a Cercopithecus sp. monkey, which had been presented to the team by villagers within the Katako-Kombe Health Zone, of the DRC. During the investigation, two of these monkeys, a Spot-nosed monkey, Cercopithecus ascanius, and a Debrazza monkey, Cercopithecus neglectus, were both tested for the presence of monkeypox using the monkeypox virus plaque reduction neutralization antibody assay, and both were found to be negative.
