Hydatid disease in Pondicherry.

An analysis of hospital and laboratory records for the period of 1971-1979 revealed 45 confirmed cases of hydatid disease. The majority were young adult (21-30 years) labourers. The commonest site of lesion was lower lobe of the left lung with the liver occupying second place. A few uncommon sites of involvement were also observed. Casoni's test was positive in 48% of cases. Eosinophilia was a usual associated finding. This report shows Pondicherry to be endemic for hydatid disease.
