Mpox virus (MPXV): comprehensive analysis of pandemic risks, pathophysiology, treatments, and mRNA vaccine development.

Mpox, formerly known as monkeypox, is a zoonotic disease caused by the Mpox virus (MPXV), which has recently attracted global attention due to its potential for widespread outbreaks. Initially identified in 1958, MPXV primarily spreads to humans through contact with infected wild animals, particularly rodents. Historically confined to Africa, the virus has expanded beyond endemic regions, with notable outbreaks in Europe and North America in 2022, especially among men who have sex with men (MSM). The World Health Organization (WHO) has declared the current Mpox outbreak a Public Health Emergency of International Concern. This review explores the epidemiology, pathophysiology, and clinical manifestations of MPXV, along with current treatment strategies and the role of mRNA vaccines. It emphasizes the importance of understanding the changing dynamics of Mpox transmission, which are influenced by factors such as waning immunity from smallpox vaccinations and increased global interconnectedness. The potential for developing multi-epitope vaccines that can stimulate robust immune responses is highlighted, showcasing how bioinformatics can facilitate the identification of immunogenic antigens. Continued research and investment in vaccine development are crucial to address the urgent need for effective candidates that can protect at-risk populations. In summary, this review underscores the necessity for proactive public health measures and collaborative efforts among healthcare authorities, researchers, and communities to mitigate the impact of Mpox and enhance global preparedness for future outbreaks.
