WHO declares mpox a global public health emergency for the second time in two years. This decision comes in response to a significant outbreak in the Democratic Republic of Congo (DRC) that has now spread to neighboring countries, raising alarms about the potential for wider international transmission.
New Variant Fuels Rapid Spread
The current outbreak began with the spread of an endemic strain known as clade I in the DRC. However, the situation took a more serious turn with the emergence of a new variant, clade Ib. This new strain appears to have enhanced transmissibility, spreading more easily through routine close contact, including sexual transmission. The rapid proliferation of this variant has been a key factor in the WHO’s decision to elevate the threat level.
The outbreak has already expanded beyond the DRC’s borders, with cases reported in Burundi, Kenya, Rwanda, and Uganda. This cross-border spread has heightened concerns about the potential for a wider African epidemic and possible global transmission. WHO Director-General Tedros Adhanom Ghebreyesus emphasized the gravity of the situation, stating, “The detection and rapid spread of a new clade of mpox in eastern DRC, its detection in neighbouring countries that had not previously reported mpox, and the potential for further spread within Africa and beyond is very worrying.”
WHO declares mpox a global public health emergency: Africa’s Mounting Crisis
The impact of this outbreak is particularly severe in Africa. The continent’s top public health body has declared its own mpox emergency, citing alarming statistics. In 2024 alone, there have been over 17,000 suspected cases and more than 500 deaths, with children in Congo bearing the brunt of the outbreak. These numbers underscore the urgent need for a robust and coordinated response to contain the spread and mitigate its impact on vulnerable populations.
Professor Dimie Ogoina, chair of WHO’s mpox emergency committee, noted that the current upsurge of cases represents an “extraordinary event,” with the DRC experiencing a record number of infections. This assessment played a crucial role in the unanimous decision to declare a global health emergency.
Challenges in Containment and Prevention
Unlike the previous global outbreak in 2022, which primarily affected men who have sex with men and was eventually contained through vaccination and behavioral changes, the current situation presents unique challenges. In the DRC and surrounding areas, the transmission routes of the new variant are not yet fully understood, necessitating further study to develop effective containment strategies.
A significant obstacle in the fight against this outbreak is the lack of available vaccines in the affected regions. Efforts are underway to address this shortage, with the WHO appealing to countries with vaccine stockpiles to donate doses. However, questions remain about the most effective vaccination strategy and which populations should be prioritized.
WHO declares mpox a global public health emergency: Global Response and Funding
The WHO has taken immediate action by releasing $1.5 million in contingency funds to support initial response efforts. However, this is just a fraction of the estimated $15 million required for a comprehensive response plan. Tedros has announced plans to appeal to donors for additional funding, highlighting the need for a swift and well-resourced international effort to combat the outbreak.
The declaration of a Public Health Emergency of International Concern (PHEIC) is intended to accelerate research, funding, and international cooperation in containing the disease. This highest level of alert from the WHO serves as a call to action for the global community, emphasizing the need for a coordinated and robust response to prevent further spread and save lives.
The current situation draws parallels with the 2022 mpox outbreak, which was also declared a global health emergency. That outbreak was eventually contained through a combination of vaccination campaigns and public health measures. However, the new variant and its different patterns of spread present fresh challenges that will require innovative approaches and strong international collaboration.
As the world grapples with this new mpox emergency, several key actions are crucial:
1. Intensified research to understand the transmission dynamics of the new variant
2. Rapid development and deployment of vaccination strategies in affected areas
3. Strengthening of surveillance and early warning systems to detect new cases quickly
4. Enhanced international cooperation to share resources, knowledge, and best practices
The coming weeks and months will be critical in determining the trajectory of this outbreak. With prompt and coordinated action, there is hope that the spread can be contained and the impact minimized. However, the situation underscores the ongoing vulnerability of global populations to emerging and re-emerging infectious diseases, highlighting the need for sustained investment in public health infrastructure and disease surveillance systems worldwide.
WHO declares mpox a global public health emergency, it presents a significant challenge to international public health. As the WHO and national health authorities work to contain the outbreak, the coming period will be crucial in determining whether this new threat can be effectively managed or if it will escalate into a more widespread global health crisis. The response to this emergency will test the world’s ability to learn from past outbreaks and apply those lessons to tackle new and evolving threats to public health.
