A Study of Frequency and Secular Trends of Seropositivity for Cysticercosis in Peru Over 20 Years

Over 20 years, the demand for cysticercosis serology and the numbers of seropositive cases by 5-year periods decreased while the proportion of seropositive cases rose significantly within a single specialised referral centre. While data from suspected clinical cases do not necessarily represent disease burden at the population level, the reduction in case numbers may represent reduced disease prevalence. At the same time, the persistence of significant numbers of cases in this single centre study through the last examined period and the increased proportion of strong seropositive cases demonstrate that cysticercosis is still endemic in Peru.
