Occupational exposure of cashew nut workers to Kyasanur Forest disease in Goa, India
Abstract:
A series of suspected cases of Kyasanur Forest disease (KFD) in subjects returning to Belgaum in Karnataka State from Goa, India, is reported herein. KFD was confirmed in 13 out of 76 cases, either by real time RT-PCR or IgM ELISA. No case fatality was recorded. KFD virus positivity was also recorded among humans and monkeys from Sattari taluk in Goa during the same period. The envelope gene sequence of positive human samples from Belgaum showed highest identity of 99.98% to 99.99% with sequences of KFD virus isolated from human cases and monkeys from Goa. KFD activity has been reported from Goa among humans and monkeys since 2015. However, it has not been reported from Belgaum to date. These findings suggest that the cases (migrant laborers) contracted infection during cashew nut harvesting from KFD-affected Keri village, Sattari taluk, Goa and became ill after or during migration from the affected area to their native residence.
