The forecast for the number of reported yellow fever cases in Brazil shows a steady increase from 483 cases in 2024 to 506 cases by 2028. This forecasted growth indicates a year-on-year increase of approximately 1.2% in yellow fever cases. As of 2023, the actual reported cases were slightly lower, establishing a base for this continuous rise over the forecasted period. This trend suggests a gradual escalation in incidence rate, requiring increased monitoring and preventive measures.

Future trends to watch for include:

Potential impacts of climate change on mosquito populations, influencing the spread of yellow fever.
Development and distribution of vaccines that could alter the projected trends.
Public health initiatives to enhance awareness and preventive actions, potentially reducing the growth rate of reported cases.
