Context
The World Health Organization (WHO) has declared the latest mpox outbreak a Public Health Emergency of International Concern (PHEIC), the highest level of global health emergency. This decision comes amidst a concerning rise in cases, particularly in the Democratic Republic of Congo (DRC) and neighbouring countries, as well as the emergence of a new, more transmissible strain of the virus.
What is Mpox?
Mpox, previously known as monkeypox, is a viral infection caused by the mpox virus (MPXV). The disease typically presents with flu-like symptoms, such as fever, headache, muscle aches, and swollen lymph nodes, followed by a characteristic rash that can last for two to three weeks. While usually mild, mpox can lead to severe complications and, in rare cases, death, especially among children and immunocompromised individuals.
The Current Outbreak
- The current outbreak is driven by the spread of clade Ib of the MPXV, which appears to be more easily transmitted through sexual contact compared to previous strains.
- As of August 2024, at least 99,176 cases and 208 deaths due to mpox have been reported from 116 countries since 2022, according to WHO data.
- One of the most concerning aspects of the outbreak is the rapid spread of clade Ib infections in DRC and neighboring countries, such as Burundi, Kenya, Rwanda, and Uganda, where mpox was previously endemic but not transmitted through sexual contact.
- This new mode of transmission, coupled with an overall increase in cases, has prompted the WHO to sound the alarm and declare a PHEIC.
Implications of the PHEIC Declaration
The PHEIC declaration is the WHO’s highest level of global health emergency and is designed to accelerate research, funding, and international cooperation to contain the outbreak. It also triggers specific measures, such as:
- Increased surveillance and reporting: Countries are required to report mpox cases and deaths to the WHO, providing a clearer picture of the global situation.
- Coordination of international response: The declaration facilitates the coordination of resources, expertise, and public health measures among countries to combat the outbreak.
- Potential travel and trade restrictions: While the WHO does not recommend any general restrictions on travel or trade, the PHEIC declaration allows countries to implement such measures if necessary.
- Prioritization of research and development: The declaration prioritizes the development of vaccines, treatments, and diagnostic tools to combat the outbreak.
Challenges and Concerns
The current outbreak poses several challenges and concerns:
- Spread to new regions: The emergence of clade Ib infections in countries previously unaffected by mpox raises the risk of further global spread, particularly through international travel.
- Potential for increased transmission: The apparent ease of transmission of clade Ib through sexual contact could lead to a rapid rise in cases if not contained effectively.
- Limited access to vaccines and treatments: Many countries, especially in Africa, lack adequate access to mpox vaccines and treatments, which could hinder efforts to control the outbreak.
- Potential for stigmatization: As the virus spreads primarily through close contact, including sexual contact, there is a risk of stigmatization and discrimination against affected communities.
Response and Preparedness
To address the outbreak, the WHO and national health authorities are implementing various measures:
- Strengthening surveillance and reporting: Improving case detection, contact tracing, and data sharing among countries.
- Increasing access to vaccines and treatments: Working with manufacturers to ensure equitable distribution of mpox vaccines and treatments.
- Engaging with affected communities: Collaborating with communities to raise awareness, reduce stigma, and promote prevention measures.
- Accelerating research and development: Supporting the development of new vaccines, treatments, and diagnostic tools through international cooperation and funding.
- Preparing for potential future outbreaks: Learning from the current outbreak to enhance preparedness and response capabilities for future mpox or other emerging infectious disease threats.
Conclusion
The declaration of the mpox outbreak as a PHEIC underscores the seriousness of the situation and the need for a coordinated global response. As the virus continues to evolve and spread, it is crucial for the international community to work together to contain the outbreak, protect vulnerable populations, and prevent future health emergencies. By prioritizing research, ensuring equitable access to vaccines and treatments, and engaging with affected communities, we can effectively address the mpox threat and build a more resilient global health system.
