A statistical study has been made of the records of respiratory infection in a portion of Wensleydale, Yorkshire, over the period 1933–46, which included three major English influenza A epidemics and one B epidemic.Each of these epidemics is recognizable in the Yorkshire records. When the incidence in the eight groups of villages comprising the district is compared there is a significant negative correlation between incidence in 1933 and 1936–7, which is taken as indicating the persistence of group immunity following an influenza A epidemic for 4 years.There was a significant positive correlation between the incidence of the 1943–4 (A) and 1945–6 (B) epidemics.
