Seroprevalence of human cystic echinococcosis: A study from a tertiary care center of North India

Present study retrospectively analysed the serological data of patients suspected of cystic echinococcosis (CE) attending the outpatient clinics or admitted in our hospital. An enzyme-linked immunoassay was used to analyse anti-CE antibodies in serum samples of 3680 patients. Microscopy of aspirated cystic fluid was performed on 170 cases only. CE seropositive cases were 595 (16.2%), of which 293 (49.2%) were males and 302 (50.8%) were females. A higher percentage of seropositivity was found in adults within age range of 21–40 years of age. There has been a decrease in seropositivity in the study years (2016–2021) in comparison to previous years (1999–2015).
