HC Deb 11 April 1935 vol 300 cc1346-7W

asked the Minister of Health the cause of the heavy increase in cases of diphtheria and deaths from that disease recorded in Leeds during the year 1934, the mortality from diphtheria that year being the highest registered since 1913; whether his statistics show if the increase in immunisation at Leeds have produced large numbers of carriers who have conveyed the disease to other children while not suffering themselves or, alternatively, if there are any sanitary conditions in Leeds which account for the heavy increase in diphtheria?


I am advised that the recent experience as regards diphtheria in Leeds accords with the general upward trend in the incidence of the disease which has recently affected all the large urban centres, especially those in the West Riding of Yorkshire. The answer to the second part of the question is in the negative.
