  1. Hepatitis E : intrafamilial transmission versus waterborne spread.

    Article - En anglais

    The relative significance of intrafamilial transmission and continued water contamination in the spread of hepatitis E is not known.

    To resolve this question, two surveys were conducted during a large bimodal waterborne epidemic of hepatitis E in Kanpur, India, affecting an estimated 79 000 persons : i) April 1991 : covering 420 houses (60 houses each in seven municipal wards) selected using multistage sampling and random number tables, and ii) May 1992 : covering the same families in five municipal wards with incidence rates exceeding 1.5% in the first survey.

    The number of affected cases in each family and the time of onset of disease in each case were recorded.

    The time interval between the first ( « index ») case and the subsequent ( « later ») case (s) in each family was calculated.
