Background: Formal assessment of a surveillance system's features and its ability to achieve objectives is crucial for disease control and prevention. Since the implementation of the mpox surveillance system in Cameroon, no evaluation has been conducted.
Methods: In a cross-sectional study, we assessed the performance of the mpox surveillance system in accordance with the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) guidelines.
Article Synopsis
- Nigeria and Cameroon reported their first mpox cases in over 30 years starting in 2017 and 2018, with Nigeria's outbreak recognized as a human epidemic.
- The study focused on understanding the zoonotic transmission dynamics of the mpox virus across the Nigeria-Cameroon border, revealing ongoing cases driven by a new Clade IIb.1 lineage and highlighting significant cross-border viral spread.
- The findings indicate that southern Nigeria is likely the origin of the mpox epidemic, with evidence of a zoonotic precursor lineage present in local animal populations for over 45 years, emphasizing the persistent risk of MPXV emergence in both countries.
During 1979-2022, Cameroon recorded 32 laboratory-confirmed mpox cases among 137 suspected mpox cases identified by the national surveillance network. The highest positivity rate occurred in 2022, indicating potential mpox re-emergence in Cameroon. Both clade I (n = 12) and clade II (n = 18) monkeypox virus (MPXV) were reported, a unique feature of mpox in Cameroon.
