在婴儿全程免疫不到10％的许多发展中国家,白喉仍然呈地方性流行,估计每年有上百万人死于白喉。相反,20年代以来,美国白喉发病率却稳定下降,到1982年只发生2例,死亡率与发病率呈平行下降。木文作者重点报道了1971—81年美国非皮肤白喉的流行病学,探讨其发病率下降的可能原因,并提出持续控制白喉的措施。
Diphtheria is still endemic in many developing countries where less than 10% of whole-baby immunizations are immunized and it is estimated that millions of people die of diphtheria each year. On the contrary, since the 1920s, the incidence of diphtheria in the United States has steadily declined. Only 2 cases occurred in 1982, and mortality and morbidity dropped in parallel. The author of the woody article focused on the epidemiology of non-skin diphtheria in the United States from 1971 to 1981, and probed into the possible causes of the decline in the incidence of diphtheria and proposed measures for the continued control of diphtheria.
