The incidence of Hepatitis B in Spain has shown a significant decline over the past decade, with actual data indicating a drop from 1.4 cases per hundred thousand persons in 2013 to 0.8 cases in 2023. This represents a continuous downward trend, marked by notable year-on-year declines, particularly from 2018 to 2020. The year-on-year decline peaked in 2020 with a sharp 42.86% reduction, followed by fluctuating recovery and minor increments or stable values through to 2023.
From the forecasted data of 2024 onward, the trend is projected to continue its decline, albeit at a steadier pace. The forecast shows a decrease to 0.5 cases per hundred thousand persons by 2028, translating to a 5-year compound annual growth rate (CAGR) of approximately -6.51% and an overall reduction of 28.57% over this period.
Future Trends to Watch for:
- Emerging medical technologies and treatments, possibly lowering hepatitis B incidence rates further.
- Impact of national vaccination programs and public health policies on hepatitis B transmission.
- Potential epidemiological shifts due to demographic changes, such as migration patterns and population aging.
