A review of the incidence of cholera from 1964 through 1974 in Matlab, Bangladesh, revealed that among the villages several had very high incidence-rates. Investigation indicated that high cholera-rates in two of these villages were probably related to water contamination from a nearby cholera hospital established in 1963. The data imply that heavy contamination can overcome any immunity resulting from repeated exposure.
对1964年至1974年孟加拉国马特莱霍乱发病率的一项审查显示,在这些村庄中有几个霍乱发病率非常高。调查表明,其中两个村庄的高霍乱发病率可能与1963年在附近设立的一家霍乱医院的水污染有关。这些数据表明,严重污染能够战胜因反复接触而产生的任何免疫力。
