Paragonimiasis in tuberculosis patients in Nagaland, India.

Background: One of the infections that mimic tuberculosis (TB) is paragonimiasis (PRG), a foodborne parasitic disease caused by lung flukes of the genus . In the northeastern states of India, TB and PRG are endemic; however, PRG is rarely included in the differential diagnosis of TB.

Objective: To address limited evidence on the dual burden of TB and PRG in northeastern India, we aimed to document the prevalence of PRG among TB patients using sputum smear, stool examination for children <15 years and ELISA.
