The WHO has declared mpox a global pandemic, highlighting its rapid spread and need for coordinated international response. Learn about symptoms, transmission, and prevention.
In an unprecedented move, the World Health Organization (WHO) has declared the ongoing mpox outbreak a global pandemic, marking a significant moment in public health. This decision underscores the seriousness of the situation as the virus continues to spread across continents, raising alarms in healthcare systems worldwide. Understanding the implications of this declaration is crucial for individuals, communities, and governments as they navigate the complexities of this viral threat. This article will explore the details surrounding the WHO’s declaration, the nature of mpox, its transmission, symptoms, and the global response necessary to combat this emerging health crisis.

What is Mpox?
Mpox, formerly known as monkeypox, is a viral zoonotic disease caused by the mpox virus, which belongs to the Orthopoxvirus genus. Although it was first identified in laboratory monkeys in 1958, the disease primarily circulates in wild animals, particularly in Central and West Africa. The first human case was reported in 1970 in the Democratic Republic of the Congo (DRC).

Key Characteristics of Mpox
- Transmission: The virus can spread from animals to humans and between humans through close contact.
- Symptoms: Common symptoms include fever, rash, and swollen lymph nodes, with lesions that can last for 2 to 4 weeks.
- Clades: Mpox is categorized into two genetic clades, with recent outbreaks linked to a new strain, clade 1b, which is believed to be more transmissible.
The WHO Declaration: Context and Importance
On August 14, 2024, the WHO Director-General, Dr. Tedros Adhanom Ghebreyesus, declared the mpox outbreak a Public Health Emergency of International Concern (PHEIC). This classification signifies the highest level of alert under global health regulations, indicating that the outbreak poses a significant risk to public health across nations.
Reasons for the Declaration
- Rapid Spread: The emergence of a new clade of the mpox virus, particularly in the DRC, has raised concerns about its potential to spread further across Africa and beyond.
- Increasing Cases: As of mid-August 2024, there have been over 15,600 reported cases and 537 deaths attributed to mpox, with a significant rise in cases compared to the previous year.
- Global Implications: The WHO’s declaration aims to mobilize international resources and coordinate a unified response to curb the outbreak and prevent further transmission.
Understanding Mpox Transmission
Mpox is transmitted through several routes, making it a concern for public health officials:
Animal to Human Transmission
- Direct Contact: Handling or consuming infected animals, particularly rodents and non-human primates.
- Bites or Scratches: Contact with infected animals can lead to transmission.
Human to Human Transmission
- Close Contact: The virus spreads through direct contact with lesions, bodily fluids, or respiratory droplets from an infected person.
- Sexual Contact: The recent outbreak has shown a significant link to sexual transmission, particularly among men who have sex with men (MSM).
- Contaminated Materials: The virus can also be transmitted through contaminated clothing, bedding, or medical equipment.
Symptoms of Mpox
The incubation period for mpox ranges from 3 to 17 days, with symptoms typically lasting between 2 to 4 weeks. Initial symptoms may include:
- Fever
- Headache
- Muscle aches
- Back pain
- Swollen lymph nodes
- Chills
- Exhaustion
Following these initial symptoms, a rash often develops, starting on the face and then spreading to other parts of the body, including the palms and soles. The rash progresses through several stages:
- Flat lesions
- Raised bumps
- Blisters filled with fluid
- Pus-filled lesions
- Scabbing and healing
Global Response and Preparedness
The WHO’s declaration has prompted a coordinated global response to address the mpox outbreak. Key components of this response include:
Vaccination Efforts
- Smallpox Vaccine: The ACAM2000 and Jynneos vaccines can provide cross-protection against mpox due to the similarity between the two viruses.
- Emergency Use Listing: The WHO has initiated the Emergency Use Listing process for mpox vaccines, which will accelerate vaccine access for lower-income countries.
Funding and Resources
- Immediate Funding Needs: WHO anticipates an initial funding requirement of $15 million to support surveillance, preparedness, and response activities.
- International Collaboration: WHO is working with countries and vaccine manufacturers on potential vaccine donations and coordinating with partners to facilitate equitable access to vaccines, therapeutics, and diagnostics.
Common Questions and Concerns
How Serious is Mpox?
While mpox can lead to severe illness, most cases are mild and self-limiting. However, complications can occur, particularly in vulnerable populations such as children and immunocompromised individuals.
What Should I Do if I Suspect Infection?
If you develop symptoms consistent with mpox, such as a new rash or fever, it is essential to contact a healthcare professional immediately for evaluation and potential testing.
Is Mpox Contagious?
Yes, mpox is contagious, but it does not spread easily between people without close contact. Awareness of the transmission routes can help mitigate the risk of infection.
Conclusion
The WHO’s declaration of mpox as a global pandemic is a critical call to action for governments, healthcare providers, and communities worldwide. As the virus spreads and evolves, understanding its transmission, symptoms, and prevention strategies is essential for managing and controlling its impact.
In this rapidly changing landscape, staying informed and proactive is the best defense against mpox. Continued research, vaccination efforts, and public health education will be vital in preventing future outbreaks and protecting public health.
