The forecast for mumps cases in the US indicates a steady increase, with cases expected to rise from 5.05 thousand in 2024 to 5.80 thousand in 2028. From 2023's baseline of 4.87 thousand cases, this represents a consistent upward trend. Year-on-year growth rates from 2024 to 2025 show a 3.76% increase, continuing at similar rates through 2028. Over this five-year span, the average annual growth rate (CAGR) is anticipated to be a constant, signaling the persistence of contributing factors to mumps outbreaks.
Future trends to watch for include potential impacts of vaccine coverage rates, public health policies, and changes in population density on mumps transmission. Monitoring these factors could provide insights into mitigating rising case numbers and controlling future outbreaks.
