Abstract

Utilizing mpox case data from Burundi between August 2024 and April 2025, we calibrated a mathematical model to quantify the temporal trends of clade Ib monkeypox virus transmission. The model outputs indicated a declining overall transmission trend. Children aged 0-4 and 5-9 years were estimated to be at higher risk of infection compared to older age groups, while sexual contact was inferred to contribute up to 50% of the overall transmission.
