Human hydatidosis: an under discussed occupational zoonosis in India

Abstract

Abstract Human hydatidosis is an important public health issue in India and many other developing countries. There is lack of data related to occurrence of this disease in certain risk groups. The present study was therefore designed to assess the seroprevalence of human hydatidosis among occupational risk groups in Punjab (India). One hundred and forty nine human serum samples from dog handlers, veterinarians/para veterinarians, dairy farmers, patients with liver disorders, HIV positives and control group (visiting hospital for other problems) were collected and analyzed using a commercially available enzyme linked immunosorbent assay (ELISA). The results revealed that 23 (15.43 %) subjects were seropositive for human hydatidosis. High seropositivity were recorded in dog handlers (30 %), followed by the other risk group populations. Relative risk of being infected was found to be 4.80 times high in dog handlers when compared to control group population. Future studies must be planned to determine the significance of these findings and the status of human hydatidosis in India.
