WHO declared MPox a Global Health emergency

On 14 August 2024, the World Health Organization (WHO) declared Mpox a Public Health Emergency of International Concern (PHEIC), drawing attention to a significant rise in cases of this viral infection, particularly in parts of Africa.

Mpox, formerly known as Monkeypox, is caused by the Orthopoxvirus, which is closely related to the now eradicated smallpox virus.

The upsurge of cases and the emergence of new viral clades have raised alarm globally, especially after the large-scale Mpox outbreak in 2022, which had ripple effects worldwide.

What is Monkeypox?

Mpox, previously termed Monkeypox, is a rare but serious viral disease. It primarily affects humans and certain animals.

Discovered in 1958 in monkeys, the first human case was identified in the Democratic Republic of the Congo (DRC) in 1970.

Initially native to central and western African countries, the virus spread globally during the Mpox cases 2023, raising fears about its potential for massive outbreaks, similar to the Monkey Pox Rash saw during previous smallpox epidemics.

Transmission and Causes of Monkeypox

Mpox spreads through direct contact with infected animals, humans, or materials contaminated with the virus.

The Centers for Disease Control and Prevention (CDC) highlights two main modes of transmission: zoonotic transmission (from animals to humans) and human-to-human transmission through respiratory droplets, bodily fluids, or skin lesions. Notably, the virus can spread through sexual networks, as indicated by recent findings.

In the Mpox outbreak of 2022-2023, several cases were linked to transmission via close, intimate contact. The CDC has worked extensively to study these modes of spread, particularly in regions where Mpox had previously not been prevalent.

Symptoms of Mpox

Monkeypox symptoms are quite similar to those of smallpox but are usually less severe. They include:

• Fever
• Headaches
• Muscle aches
• Fatigue
• Swollen lymph nodes

However, the hallmark of Mpox is the Monkey Pox Rash, which starts as small, red bumps and eventually progresses into fluid-filled blisters, similar to chickenpox.

The symptoms of pox generally appear 7-14 days after exposure and can last for 2 to 4 weeks.

Recent studies have highlighted that Monkeypox symptoms can vary based on the viral clade.

For example, Clade 1b, recently detected in parts of Africa, has been shown to spread more rapidly through close human contact and is often more severe, especially in immunocompromised individuals.

Mpox Outbreak:

The Monkeypox outbreak of 2023 saw over 14,000 reported cases, with the most severe impacts seen in Africa.

According to the CDC, the outbreak began in countries like the Democratic Republic of the Congo (DRC) and soon spread to neighboring countries, including Uganda, Rwanda, and Kenya.

The spread was accelerated by the high transmission rate of new viral clades.

Dr. Tedros Adhanom Ghebreyesus, WHO’s Director-General, explained that the rise in Mpox cases was exacerbated by global health inequities, with many affected African countries struggling to access diagnostics, vaccines, and treatments.

He called for urgent international cooperation to prevent further spread, particularly in regions that had yet to see significant outbreaks.

The CDC and WHO have developed detailed guidelines for managing Monkeypox outbreaks, emphasizing public health preparedness, contact tracing, and vaccination campaigns.

During the Monkeypox cases 2023, these organizations partnered with local health agencies to distribute vaccines and conduct educational outreach in vulnerable communities.

Monkeypox Cases 2023:

The year 2023 marked a significant turning point for Mpox, with a surge in reported cases. Mpox cases 2023 were driven by several factors:

1. Delayed detection and diagnosis: Many cases went undetected in their early stages, especially in under-resourced regions.
2. Emergence of new viral clades: Clade 1b, in particular, proved more transmissible and virulent.
3. Inadequate vaccination coverage: Despite the availability of two WHO-approved vaccines, many African countries lacked access to them.
4. Global mobility and travel: The relaxation of pandemic-related travel restrictions may have contributed to the spread of Mpox to new regions.

The Centers for Disease Control and Prevention worked closely with WHO to track these developments. They highlighted how the rapid spread of new Mpox clades caught many public health systems off-guard.

Prevention and Vaccines of MonkeyPox

In response to the Mpox outbreak, public health officials have emphasized several strategies:

1. Early detection: Rapid identification of Mpox symptoms and isolation of infected individuals are crucial to halting the virus’s spread.
2. Vaccination: The CDC and WHO have recommended using the JYNNEOS and ACAM2000 vaccines, both of which have shown efficacy against Mpox. A global vaccine distribution effort is underway to ensure equitable access to these vaccines, particularly in lower-income countries.
3. Public awareness: Governments are working to raise awareness of the Monkey Pox Rash and symptoms of pox through media campaigns and educational outreach.
4. Hygiene and sanitation: Good personal hygiene, such as frequent hand washing, and disinfection of surfaces are key to reducing transmission.

As of 2024, the WHO has mobilized over $15 million to support Mpox prevention and control efforts. This includes funding for testing, vaccination, and public health campaigns in high-risk areas.

Recognizing and Differentiating Mpox

One of the most crucial aspects of controlling the Mpox outbreak lies in educating the public about the symptoms of pox.

Since Mpox can be easily confused with other viral infections such as chickenpox or measles, accurate and timely diagnosis is essential.

The Monkey Pox Rash typically begins on the face and spreads to other parts of the body. This rash undergoes several stages: macules (flat lesions), papules (raised bumps), vesicles (fluid-filled blisters), and pustules (pimple-like formations).

The rash eventually forms scabs that fall off over time, completing the infection cycle.

Healthcare professionals are urged to keep an eye out for other Mpox symptoms, such as swollen lymph nodes, which distinguish it from chickenpox.

Prompt diagnosis and reporting of these symptoms can help in containing further spread, especially in areas witnessing high Mpox cases 2023.

The Role of the CDC in Mpox Control

The Centers for Disease Control and Prevention (CDC) has been at the forefront of efforts to monitor and respond to the Mpox outbreak.

Their guidelines, developed in partnership with the WHO, cover everything from surveillance to clinical management. Here’s a brief look at the CDC’s role:

• Disease Surveillance: The CDC has been closely tracking Mpox cases globally, issuing regular updates and situational reports.
• Public Health Interventions: The CDC has spearheaded initiatives aimed at reducing transmission, including contact tracing and promoting vaccination campaigns.
• Research and Development: The CDC continues to study the virus’s transmission patterns and mutations, with a particular focus on understanding the new viral clades, such as Clade 1b.

The Mpox outbreak has served as a reminder of the importance of strong global public health institutions like the CDC, which play a critical role in outbreak response and management.

Conclusion

The WHO’s recent declaration of Mpox as a Public Health Emergency of International Concern is a stark reminder of the ongoing challenges posed by viral outbreaks.

With the surge in Mpox cases 2023 and the emergence of new viral clades, the global health community must remain vigilant.

Public health measures such as early detection, vaccination, and international cooperation will be crucial in bringing the Mpox outbreak under control and preventing future epidemics.

As the CDC and WHO continue their efforts to contain the virus, public awareness remains key. The more we know about the symptoms of pox and the Monkey Pox Rash, the better equipped we will be to fight this virus and stop its spread.
