The world has been grappling with a series of public health emergencies in recent years, from the COVID-19 pandemic to the resurgence of polio. Now, a new global health crisis has emerged – the rapidly spreading monkeypox outbreak. On July 23, 2022, the World Health Organization (WHO) Director-General, Dr. Tedros Adhanom Ghebreyesus, made the momentous decision to declare the monkeypox outbreak a Public Health Emergency of International Concern (PHEIC). This declaration signifies the gravity of the situation and the urgent need for a coordinated global response.

The Escalating Monkeypox Outbreak
The monkeypox virus, which has traditionally been confined to central and western Africa, has now spread to over 70 countries worldwide, including many nations where the virus had never been detected before. Since May 2022, more than 17,300 confirmed and suspected cases have been identified across six WHO regions, with the vast majority reported in the WHO European Region.
The rapid and unprecedented spread of monkeypox has caught the global health community by surprise. While the virus typically spreads through close contact and after the onset of symptoms, the current outbreaks have shown a concerning pattern of transmission, with many cases linked to sexual networks, particularly among men who have sex with men (MSM). This shift in the epidemiology of the disease has raised concerns about the potential for further spread beyond the initial affected communities.
Factors Driving the Global Spread of Monkeypox
Several factors have contributed to the global dissemination of monkeypox. Firstly, the emergence of a new and potentially more transmissible clade of the virus in the Democratic Republic of the Congo (DRC) has sparked alarm. This new viral strain, known as clade 1b, appears to be spreading primarily through sexual networks, making it more challenging to contain.
Secondly, the waning immunity to orthopoxviruses, including monkeypox, in the general population since the discontinuation of routine smallpox vaccination has left many individuals vulnerable to infection. The lack of widespread vaccination coverage, particularly in regions where monkeypox has been historically endemic, has exacerbated the situation.
Moreover, the limited availability and unequal distribution of monkeypox vaccines and treatments have hampered the ability of countries to effectively respond to the outbreaks. High-income nations have been quick to secure vaccine supplies, while low- and middle-income countries, particularly in Africa, have struggled to access these crucial resources.

WHO’s Declaration of a Public Health Emergency of International Concern
The WHO’s decision to declare the monkeypox outbreak a PHEIC was not taken lightly. The declaration came after an emergency committee convened by the WHO reviewed the available data and advised the Director-General that the situation meets the criteria for a PHEIC under the International Health Regulations (2005).
A PHEIC is defined as “an extraordinary event which is determined to constitute a public health risk to other States through the international spread of disease and to potentially require a coordinated international response.” This designation underscores the global nature of the monkeypox crisis and the need for a unified, collaborative effort to contain the virus.
Implications of the PHEIC Declaration
The PHEIC declaration carries significant implications for the global response to the monkeypox outbreak. It serves as a call to action for countries, international organizations, and public health authorities to intensify their efforts in several key areas:
Strengthening Surveillance and Reporting
The PHEIC declaration emphasizes the importance of robust surveillance and reporting systems to track the spread of monkeypox accurately. This includes expanding access to diagnostic testing, improving case identification, and enhancing data sharing among nations.
Coordinating International Response
The PHEIC status mandates a coordinated international response, with the WHO taking a central role in facilitating collaboration, resource allocation, and the implementation of evidence-based strategies to curb the outbreak.
Ensuring Equitable Access to Vaccines and Treatments
The declaration underscores the urgent need to address the inequitable distribution of monkeypox vaccines and treatments, ensuring that low- and middle-income countries have fair and timely access to these crucial tools.
Combating Stigma and Discrimination
The WHO has emphasized the importance of addressing the stigma and discrimination that have often accompanied monkeypox outbreaks, particularly among marginalized communities. Inclusive, non-discriminatory public health messaging and community engagement will be crucial in this regard.
Challenges and Obstacles in the Global Response
Despite the PHEIC declaration, the global response to the monkeypox outbreak faces several challenges and obstacles that must be overcome:
Limited Testing Capacity
Many countries, especially in the Global South, lack the necessary infrastructure and resources to conduct widespread testing for monkeypox. This hampers efforts to accurately identify and track the spread of the virus.
Vaccine Shortages and Inequitable Distribution
The limited global supply of monkeypox vaccines and the prioritization of high-income nations in securing these resources have created significant disparities in access, particularly for countries in Africa where the virus has been endemic for decades.
Inadequate Funding and Resources
The WHO has appealed for immediate funding of $15 million to support surveillance, preparedness, and response activities. However, the reality is that the global health community faces competing priorities and limited resources, which could hinder the effective implementation of the necessary interventions.
Gaps in Scientific Understanding
While the monkeypox virus has been known to science for over 50 years, there are still significant gaps in our understanding of the virus’s epidemiology, modes of transmission, and the potential for mutations that could alter its behavior and impact.
The Crucial Role of Collaboration and Solidarity
Overcoming the challenges posed by the monkeypox outbreak will require a concerted effort of global collaboration and solidarity. This includes:
Strengthening International Cooperation
Fostering meaningful cooperation and information-sharing among nations, international organizations, and public health authorities will be crucial in coordinating a unified response.
Empowering Local Communities
Engaging with and empowering local communities, particularly those most affected by the outbreak, will be essential in developing culturally appropriate and effective intervention strategies.
Investing in Preparedness and Resilience
Building robust public health infrastructure, strengthening disease surveillance systems, and investing in research and development for monkeypox diagnostics, vaccines, and treatments will enhance global preparedness and resilience against future outbreaks.

The Urgency of Action and the Path Forward
The WHO’s declaration of monkeypox as a global public health emergency underscores the gravity of the situation and the need for immediate, decisive action. Failure to mount an effective and equitable global response risks the further entrenchment of the virus, potentially leading to devastating consequences for vulnerable populations and the global health landscape.
As the world grapples with this evolving public health crisis, it is crucial that governments, international organizations, and the global health community come together to implement a comprehensive and coordinated strategy. This strategy must prioritize strengthening surveillance, ensuring equitable access to vaccines and treatments, combating stigma and discrimination, and fostering a spirit of international cooperation and solidarity.
Only through a unified, proactive, and evidence-based approach can the world overcome the monkeypox challenge and safeguard the health and well-being of people worldwide. The time for action is now, and the global community must rise to the occasion, drawing upon the lessons learned from past public health emergencies to chart a path towards a safer, more resilient future.
