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. In this particular view, standing outdoors in front of a Katako-Kombe Health Zone village laboratory's 'hot line', R. Joel Williams, D.V.M., was pictured wearing a suit of medical scrubs, latex gloves, and a facemask, as he was handling two newly-acquired Gambian rats, Cricetomys emini. During the epidemiologic study, 19 Gambian rats were tested for monkeypox, using the monkeypox virus plaque reduction neutralization antibody assay, resulting in 3 testing positive.
