A critical perspective of prion disease surveillance in Brazil

Key Points

Prion disease surveillance in Brazil is severely hindered by underreporting, affecting data accuracy.
The expected number of prion disease cases is around 3,200, highlighting the issue of missed diagnoses.
Data limitations stem from reliance on a database meant for epidemic outbreaks, leading to inconsistencies.
Improvements since 2005 remain insufficient, underscoring the need for a specialized database for CJD.

Abstract

In this period, the expected number of cases for the Brazilian population would be 3,200. Additionally to underreporting, the data shared by MH is limited due to the use of a database destined to mainly observe epidemic outbreaks and mismatches between official documents. Despite some progress since 2005, PrD surveillance in Brazil faces significant problems, due to the inaccurate treatment of these data and the lack of a specific database for CJD.
