Mpox: A New Global Health Emergency and Its Implications

Context:

The World Health Organization (WHO) declared the mpox outbreak in the Democratic Republic of the Congo and other African nations as a “global health emergency” on August 14, 2024. This declaration, made by WHO Director-General Tedros Adhanom Ghebreyesus based on the advice of an International Health Regulations (IHR) emergency committee, underscores the seriousness of the ongoing mpox crisis.

The outbreak, which began in 2022, has continued to spread, with a significant surge in cases reported recently.
This editorial analysis explores the reasons behind this global health emergency, the nature of mpox, its implications, and the path forward in combating this outbreak.

Understanding the Mpox Outbreak:

The mpox outbreak, which has escalated into a global health emergency, represents a significant public health challenge. Originally confined to certain regions in Africa, the disease has now spread across the globe, affecting over 116 countries with more than 15,600 cases and 537 deaths reported this year alone. The severity of the situation has prompted the WHO to reclassify the outbreak as an “acute” grade 3 emergency, the highest level of response in the WHO Emergency Response Framework.
The decision to declare mpox a global health emergency highlights the need for coordinated international efforts to contain the spread of the disease and prevent it from escalating into a more widespread public health crisis.

WHO’s Role and Response:

The World Health Organization plays a crucial role in managing global health crises. The declaration of mpox as a global health emergency is a call to action for countries worldwide to take immediate and decisive measures to control the outbreak. The WHO’s emergency committee, which provides strategic guidance during such crises, has emphasized the need for a major response, particularly in countries with the highest number of cases, such as the Democratic Republic of the Congo and its neighbors.
The WHO’s declaration also serves as a warning to the international community about the potential for the mpox outbreak to expand further, potentially leading to a pandemic if not adequately addressed.

About Mpox:

What is Mpox?

Mpox, also known as monkeypox, is a rare zoonotic disease, meaning it is transmitted from animals to humans. The disease is caused by the monkeypox virus, which belongs to the Orthopoxvirus genus in the Poxviridae family. This family of viruses also includes the viruses responsible for smallpox and cowpox.
The exact source of the mpox virus remains unclear, though it is believed that small mammals, such as squirrels and monkeys, serve as carriers. Two distinct clades, or genetic groups, of mpox exist: clade I, predominantly found in central and east Africa, and clade II, more commonly linked to cases in west Africa.

Transmission and Symptoms:

The mpox virus is primarily transmitted to humans through physical contact with an infected individual or animal. This can occur through direct contact with infected blood, bodily fluids, or lesions on the skin or mucous membranes. The virus can also spread through contact with contaminated materials, such as bedding or clothing, or through bites or scratches from infected animals.
Symptoms of mpox typically begin within one week of infection but can start anywhere from 1 to 21 days after exposure. The disease often presents as a rash that can develop into fluid-filled blisters, which may be itchy or painful. Other common symptoms include fever, sore throat, headache, muscle aches, back pain, low energy, and swollen lymph nodes. The symptoms usually last 2-4 weeks, and while most individuals experience mild symptoms, certain groups, such as children, pregnant women, and immunocompromised individuals, are at higher risk of severe illness.

Why Mpox is a Global Health Emergency:

Escalating Cases and Global Spread:

The mpox outbreak, which began in 2022, has not only persisted but has also seen a recent surge in cases worldwide. The rapid and widespread transmission of the virus has raised alarm, leading to its classification as a global health emergency. The situation is particularly dire in the Democratic Republic of the Congo and neighboring African countries, where the highest number of cases and deaths have been reported.
The global spread of mpox, with cases now reported in countries outside Africa, including Pakistan and Sweden, underscores the need for a coordinated international response. The WHO’s declaration of a public health emergency of international concern (PHEIC) is intended to mobilize global resources and attention to contain the outbreak before it evolves into a more severe health crisis.

Challenges in Containing the Outbreak:

Containing the mpox outbreak presents several challenges, particularly in resource-limited settings where healthcare infrastructure may be inadequate to manage a surge in cases. The spread of the virus across multiple continents complicates containment efforts, as it requires coordination between countries with varying levels of healthcare capacity and resources.
Another significant challenge is the lack of specific treatment options for mpox. While supportive care can help manage symptoms, there is currently no targeted antiviral treatment widely available. Moreover, the availability of vaccines is limited, and mass vaccination is not recommended by the WHO, further complicating efforts to prevent the spread of the virus.

Implications of the Mpox Outbreak:

Health and Economic Impact:

The mpox outbreak has significant health implications, particularly for vulnerable populations. The risk of severe illness and complications in children, pregnant women, and immunocompromised individuals necessitates a robust public health response to protect these groups. Additionally, the outbreak has placed a strain on healthcare systems, particularly in regions with limited resources.
Economically, the outbreak has the potential to disrupt trade, travel, and other sectors, particularly if it continues to spread globally. The cost of managing the outbreak, including the provision of healthcare services, vaccines, and public health interventions, can place a significant burden on national economies, particularly in low- and middle-income countries.

Global Health Security Concerns:

The mpox outbreak raises broader concerns about global health security. The spread of zoonotic diseases, particularly those with pandemic potential, highlights the need for stronger surveillance systems, better preparedness, and more effective international cooperation. The outbreak also underscores the importance of addressing the root causes of zoonotic diseases, including wildlife trade, deforestation, and other human activities that increase the risk of animal-to-human transmission.

Suggested Measures for Containment and Control:

Strengthening Surveillance and Reporting: Early detection of cases, particularly in regions with active transmission, is essential for timely intervention and containment.
Promoting Public Awareness and Education: Public health authorities should work with local leaders, community organizations, and the media to disseminate accurate information and counter misinformation about the disease.
Enhancing Healthcare Capacity: This includes increasing the availability of medical supplies, protective equipment, and healthcare workers trained in the management of infectious diseases. Ensuring that healthcare facilities are equipped to handle a potential surge in mpox cases is also critical.
