Since the beginning of 2024, over 7.5 million dengue cases and over 3 000 dengue-related deaths have been reported from 73 countries/territories. Most cases globally have been reported from the WHO PAHO region, with Brazil reporting most cases.
Prevalence data from sources such as population surveys can be a useful complement to case based surveillance data for hepatitis C. Case-based surveillance has limitations as most diagnosed cases are chronic in nature and detection of cases depends largely on testing practices. Prevalence data can therefore contribute towards a fuller understanding of the epidemiology of hepatitis C.
