The NCDC calls Mitch the deadliest Atlantic hurricane since 1780.
国家天气数据中心(NCDC)称“米奇”是1780年以来杀伤力最大的大西洋飓风。
NCDC is a part of the Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), and the National Environmental Satellite, Data and Information Service (NESDIS).
The NCDC said majority of the cases were among people who had not been vaccinated, even though diphtheria is covered by Nigeria's routine childhood immunization program.
