Mpox Declared Health Emergency in Africa: Causes, Prevention, and Global Impact

Mpox Declared Health Emergency in Africa

The World Health Organization (WHO) has recently declared mpox, formerly known as monkeypox, a public health emergency in Africa 1

. This declaration comes as the continent faces a significant outbreak of the viral disease, raising concerns about its potential spread and impact on public health.

Understanding Mpox: Causes and Transmission

Mpox is caused by the monkeypox virus, which belongs to the same family as the smallpox virus 2

. The disease is primarily transmitted through close contact with infected animals, such as rodents and primates, found in the rainforests of Central and West Africa. Human-to-human transmission can occur through close contact with respiratory secretions, skin lesions, or bodily fluids of an infected individual.

Symptoms and Progression of Mpox

The symptoms of mpox typically appear within 6 to 13 days after exposure, with an incubation period that can range from 5 to 21 days 1

. Initial symptoms include fever, intense headache, muscle aches, and fatigue. As the disease progresses, a distinctive rash develops, often beginning on the face and spreading to other parts of the body. The rash evolves through various stages before forming scabs that eventually fall off.

Prevention and Control Measures

To combat the spread of mpox, health authorities are implementing various prevention and control measures:

Vaccination: Smallpox vaccines have shown to be effective against mpox, with an estimated 85% efficacy 2
2
.
Isolation: Infected individuals are advised to isolate to prevent further transmission.
Personal hygiene: Regular handwashing and use of personal protective equipment (PPE) for healthcare workers.
Contact tracing: Identifying and monitoring close contacts of infected individuals.
Public awareness: Educating communities about the disease, its symptoms, and prevention methods.

Global Impact and Response

While the current emergency declaration focuses on Africa, the global health community remains vigilant. The WHO and other international health organizations are closely monitoring the situation and providing support to affected countries. The outbreak has prompted increased surveillance and preparedness measures in many nations to prevent potential cross-border spread.

Challenges in Containment

Several challenges exist in containing the mpox outbreak:

Limited vaccine availability in some regions.
Potential for misdiagnosis due to similarity with other rash-causing diseases.
Stigma and discrimination associated with the disease.
Difficulty in contact tracing in densely populated areas.

As the situation evolves, health authorities continue to adapt their strategies to effectively manage and contain the mpox outbreak in Africa, while remaining prepared for potential global implications.
