Mpox Outbreak: Global Situation Report #56
Mpox Situation Report: Global Epidemiology and Operational Response (July 2025)
As of July 31, 2025, the global landscape of mpox continues to evolve, demanding vigilant monitoring and a robust, coordinated response. This report, the 56th in our series, provides a comprehensive update on the multi-country outbreak, focusing on the epidemiological situation worldwide, with a specific deep dive into the dynamics within Africa. We also detail the operational response efforts as of July 23, 2025, offering critical insights for public health professionals, policymakers, and the global community.
Global Epidemiological Snapshot of Mpox
The mpox virus,a zoonotic orthopoxvirus,has presented important public health challenges since its emergence in non-endemic regions in 2022. While the initial surge has seen a decline in many areas, the virus remains endemic in several countries, primarily in Central and West Africa, and sporadic outbreaks continue to occur globally. Understanding the current epidemiological trends is paramount to effective control strategies.
Key Trends and Data (Global)
Globally, the number of reported mpox cases has stabilized compared to the peak of the 2022 outbreak. Though, vigilance is crucial as localized clusters and individual cases continue to be identified. Public health agencies are actively engaged in surveillance, contact tracing, and vaccination efforts in affected and at-risk populations.
the effectiveness of vaccination campaigns, especially with the modified vaccinia Ankara-Bavarian Nordic (MVA-BN) vaccine, has been a significant factor in mitigating transmission in many high-income countries. However, equitable access to vaccines and therapeutics remains a challenge, particularly in resource-limited settings.
Expert Insights on Global Trends
Dr. Anya Sharma, a leading infectious disease epidemiologist, notes, “While we’ve made considerable progress in understanding and managing mpox, the virus’s ability to persist and re-emerge in different contexts underscores the need for sustained global cooperation. Our focus must remain on strengthening surveillance systems, ensuring equitable access to medical countermeasures, and addressing the underlying factors that facilitate transmission.”

Mpox Epidemiology in Africa
Africa, where mpox is endemic, continues to face a distinct epidemiological challenge. The virus has circulated in animal populations and humans for decades, with different clades exhibiting varying degrees of severity and transmissibility. The recent global outbreak has brought renewed attention to the situation on the continent.
Endemic Clades and Transmission Dynamics
Africa is home to two main clades of the mpox virus: clade I and Clade II. Clade I,historically associated with more severe disease and higher mortality,is prevalent in Central Africa. Clade II, which includes the sub-clades responsible for the 2022 global outbreak, is found in West Africa. Understanding these distinctions is vital for accurate diagnosis, treatment, and public health messaging.
The transmission dynamics in Africa are complex, involving zoonotic spillover events from infected animals, human-to-human transmission through close contact with lesions, body fluids, respiratory droplets, and contaminated materials. Community-level transmission can be exacerbated by factors such as close living conditions,cultural practices involving close contact,and limited access to healthcare.
Update on Epidemiological Situation in Africa (as of July 20, 2025)
The data as of July 20, 2025, indicates a persistent presence of mpox across several African nations. While specific case numbers fluctuate,the underlying endemicity means that vigilance and robust surveillance remain critical.
Central Africa (clade I): Countries in this region continue to report sporadic cases and localized outbreaks. The severity of illness associated with Clade I necessitates prompt medical attention and isolation protocols. Efforts are focused on improving diagnostic capacity and clinical management.
West Africa (Clade II): While the global outbreak was largely driven by
