Encephalitis surveillance annual summary 1963
  • Description:
    During 1963, 2,362 cases of encephalitis, including 184 deaths were reported to the Encephalitis Surveillance Unit (ESU). Of the total, 1,285 (53 percent) were reported by etiology. Mumps and measles accounted for over two-thirds of these. Arbovirus encephalitis cases were comparatively rare, accounting for only 76 cases. Only one outbreak, in the high plains area of Texas, was recorded during 1963. Data on human cases and isolates obtained from other than human sources are summarized in Section II. Special epidemiological reports in Section III include: a description of the single recognized arbovirus outbreak in the United States during 1963; a clinical account of the first recognized human case of encephalitis attributed to the California virus; and notation regarding the isolation of Venezuelan Equine Encephalitis Virus for the first time in the United States. A description of outbreaks of Western Encephalitis in Saskatchewan and Venezuelan Equine Encephalitis illnesses in Venezuela during 1963 are described under foreign reports. A summary of equine viral encephalitis cases reported to the USDA is included in Section V.
