Mpox Resurgence Factors
In recent years, mpox has re-emerged in several regions, spreading beyond previously known geographic patterns and challenging public health systems. What key epidemiological, environmental, and social factors have contributed to the resurgence and global spread of mpox? Additionally, how should health systems strengthen surveillance, community awareness, vaccination strategies, and rapid response mechanisms to prevent future outbreaks—particularly in areas with limited public health infrastructure?

Answer:
The resurgence and global spread of mpox can be attributed to a combination of epidemiological, environmental, and social factors. Epidemiologically, mpox spreads primarily through close contact with infected humans or animals, and waning population immunity following the cessation of smallpox vaccination has increased susceptibility. The absence of cross-protective immunity has allowed more frequent outbreaks in regions where the virus was historically confined. Additionally, increased travel and trade have facilitated the movement of the virus across borders, creating opportunities for outbreaks in previously unaffected regions.
Environmental factors also play a significant role in mpox transmission. Deforestation, habitat encroachment, and increased human interaction with wildlife reservoirs, such as rodents and non-human primates, have heightened the risk of zoonotic spillover events. Climate change and alterations in ecosystems may further influence the virus’s natural reservoirs and the frequency of human exposure, creating conditions conducive to the spread of mpox. Urbanization and population density in certain regions amplify the risk of human-to-human transmission once an initial spillover occurs.
Social factors such as cultural practices, community behaviors, and levels of public awareness influence the dynamics of mpox spread. Communities with limited knowledge about the disease may not adopt preventive behaviors, increasing transmission rates. Stigma associated with infectious diseases can also discourage individuals from seeking timely medical care, thereby contributing to further spread. Social gatherings, travel patterns, and close contact networks can amplify outbreaks, particularly in urban centers or regions with interconnected communities.
To prevent future outbreaks, health systems should strengthen disease surveillance by establishing early-warning systems that detect cases promptly and track trends over time. Community awareness campaigns are crucial to educate the public about transmission routes, preventive measures, and symptoms to ensure early reporting. Vaccination strategies, including targeted immunization in high-risk populations or ring vaccination around detected cases, can limit outbreak expansion. Rapid response mechanisms should be developed to ensure swift isolation, contact tracing, and medical care for affected individuals.
In areas with limited public health infrastructure, these strategies must be adapted to local contexts. Mobile health units, community health workers, and partnerships with local leaders can help implement surveillance and awareness campaigns efficiently. Resource allocation should prioritize training, communication networks, and access to vaccines and treatment. Additionally, leveraging digital reporting tools and integrating outbreak preparedness into existing healthcare services can enhance response capabilities, even in resource-constrained settings. Ultimately, a coordinated, multi-faceted approach that combines epidemiological, environmental, and social interventions is essential to controlling the resurgence of mpox globally.
