    Abstract

    Following a recent report that neoplasia of the lymphatic and haematopoietic tissues is commoner than average in children whose mothers have had influenza in pregnancy, the incidence of neoplasms in 1954-68 in children of the Manchester Hospital Region was examined in relation to date of birth. There were no significant differences between cohorts born in different quinquennia. Incidence among children born after six influenza epidemics in 1951-68 was no higher than among other children born in these years. It is concluded that if there is an association between maternal influenza and childhood neoplasia it is probably due to factors such as immunological deficiencies which may predispose independently to both conditions.
