摘要

For the 2003 monkeypox virus (MPXV) outbreak in the United States, interhuman transmission was not docu-mented and all case-patients were near or handled MPXV-infected prairie dogs. We initiated a case–control study to evaluate risk factors for animal-to-human MPXV transmis-sion. Participants completed a questionnaire requesting exposure, clinical, and demographic information. Serum samples were obtained for analysis of immunoglobulin G (IgG) and IgM to orthopoxvirus. When data were adjusted for smallpox vaccination, case-patients were more likely than controls to have had daily exposure to a sick animal (odds ratio [OR] 4.0, 95% confi dence interval [CI] 1.2–13.4), cleaned cages and bedding of a sick animal (OR 5.3, 95% CI 1.4–20.7), or touched a sick animal (OR 4.0, 95% CI 1.2–13.4). These fi ndings demonstrate that human MPXV infection is associated with handling of MPXV-infected ani-mals and suggest that exposure to excretions and secre-tions of infected animals can result in infection
