§ Mr. Viantasked the Minister of Health why, in view of the fact that the Registrar-General has recorded in his weekly returns of disease for many years down to the beginning of the present year corrections of diagnosis of diphtheria, he cannot incorporate these in quarterly records for those years and thus make them available for comparison with the new quarterly returns, which provide for the correction of erroneous notifications received during the quarter.
§ Mr. WillinkSuch corrections of notifications of infectious diseases as the Registrar-General received prior to the present year were regularly incorporated in his published Quarterly Returns for the relevant period. Under the new system of quarterly statements supplied by Medical Officers of Health throughout the country as from the beginning of 1944, the information received is more complete and detailed than was formerly the case, and it would not be practicable in present circumstances to obtain a revision of the quarterly records for previous years which would render them comparable with the new returns.
