In recent months, Africa has been grappling with a significant surge in mpox cases, prompting health officials to declare the continent’s first-ever public health emergency.
This outbreak has raised concerns not only within Africa but also globally, as the world continues to navigate the aftermath of the COVID-19 pandemic.
In this comprehensive article, we’ll explore the current Mpox Outbreak in Africa, its implications, and the global response to this emerging crisis.
What is Mpox?
Before delving into the details of the current outbreak, it’s essential to understand what mpox is and how it spreads.Mpox, formerly known as monkeypox, is a viral disease caused by the monkeypox virus, which belongs to the same family of viruses that causes smallpox.
The disease was first discovered in 1958 in a colony of monkeys kept for research, hence its original name. However, the first human case wasn’t recorded until 1970 in the Democratic Republic of Congo (DRC).
Key Features of Mpox:
- Zoonotic disease (can spread from animals to humans)
- Causes flu-like symptoms and a distinctive rash
- Generally less severe than smallpox
- Two known clades: Clade I (more severe) and Clade II (milder)
How Does Mpox Spread?
Understanding the transmission of mpox is crucial for controlling its spread. The virus can be transmitted through:
- Close contact with infected animals: This includes bites, scratches, or consuming meat from infected animals.
- Person-to-person contact: This can occur through:
- Direct contact with bodily fluids or lesions
- Respiratory droplets during prolonged face-to-face contact
- Contact with contaminated items like bedding or clothing
- Mother-to-child transmission: The virus can be passed from a pregnant woman to her fetus.
It’s important to note that while mpox can spread through sexual contact, it is not classified as a sexually transmitted infection (STI). The close physical contact during sexual activity, rather than the sexual act itself, is what facilitates transmission.
The Current Outbreak in Africa
The recent mpox outbreak in Africa has been unprecedented in its scale and spread. Let’s break down the key aspects of this crisis:
Scale of the Outbreak
As of August 2024, the Africa Centres for Disease Control and Prevention (Africa CDC) reported alarming statistics:
- Over 37,000 confirmed cases since January 2022
- More than 1,400 deaths reported
- 15 African countries affected
The Democratic Republic of Congo (DRC) has been hit particularly hard, accounting for over 96% of all cases and 97% of deaths in 2024 alone.
New Countries Affected
Between July and August 2024, several countries reported their first mpox cases:
- Burundi
- Kenya
- Rwanda
- Uganda
This spread to new territories is particularly concerning as it suggests the virus is expanding its geographical reach.
Virus Strains Involved
The current outbreak involves multiple strains of the mpox virus:
- Clade I: Found primarily in Central and East Africa, considered more dangerous
- Clade Ib: A new variant causing concern
- Clade II: Linked to cases in West Africa
The presence of multiple strains complicates the response efforts and raises questions about the virus’s evolution.
Why is This Outbreak Different?
Several factors make the current mpox outbreak in Africa particularly concerning:
- Unprecedented Scale: The number of cases far exceeds previous outbreaks.
- Geographic Spread: The virus is appearing in countries with no prior history of mpox.
- Urban Transmission: Unlike previous outbreaks confined to rural areas, the virus is now spreading in densely populated urban centers.
- Multiple Strains: The presence of different viral strains complicates treatment and containment efforts.
- Global Context: This outbreak occurs as the world is still recovering from the COVID-19 pandemic, straining already burdened healthcare systems.
Challenges in Containing the Outbreak
African health authorities face several challenges in their efforts to contain the mpox outbreak:
Vaccine Shortage
One of the most pressing issues is the severe shortage of mpox vaccines. The Africa CDC estimates a need for about 10 million doses, but only around 200,000 are currently available. This shortfall significantly hampers efforts to control the spread of the virus.
Healthcare Infrastructure
Many affected regions lack robust healthcare infrastructure, making it difficult to diagnose, treat, and isolate cases effectively. This is particularly challenging in conflict-affected areas like parts of the DRC.
Public Awareness
There’s a need for increased public awareness about mpox, its symptoms, and prevention methods. Misinformation and stigma can hinder efforts to identify and treat cases.
Resource Constraints
Many African countries are already dealing with multiple health crises and have limited resources to allocate to mpox control efforts.
The Global Response
The mpox outbreak in Africa has prompted a global response, though some argue it’s not sufficient given the scale of the crisis.
WHO’s Response
The World Health Organization (WHO) has taken several steps:
- Regraded the global mpox outbreak to an acute grade 3 emergency, its highest alert level
- Convened emergency committee meetings to discuss the outbreak
- Provided technical guidance to affected countries
International Aid
Some countries and organizations have pledged support:
- The United States promised an additional $10 million in health assistance to the DRC and surrounding regions
- Vaccine manufacturers are in negotiations to provide doses to affected countries
However, many health experts argue that the global response has been too slow and inadequate given the potential for the outbreak to spread beyond Africa.
Impact on Different Populations
The mpox outbreak affects various populations differently:
Children
Children, especially those under 5, are at higher risk of severe disease. The outbreak has seen a concerning number of pediatric cases, particularly in the DRC.
Immunocompromised Individuals
People with weakened immune systems, including those with untreated HIV, are at higher risk of severe mpox. This is particularly concerning in regions with high HIV prevalence.
Pregnant Women
Pregnant women infected with mpox are at risk of passing the virus to their unborn children, potentially leading to complications or fetal loss.
Healthcare Workers
Frontline healthcare workers are at increased risk of exposure due to their close contact with infected individuals.
Economic and Social Implications
The mpox outbreak has far-reaching consequences beyond health:
Economic Impact
- Strain on healthcare budgets
- Potential disruption to trade and tourism
- Lost productivity due to illness and quarantine measures
Social Consequences
- Stigma associated with the disease
- Disruption to education if schools are affected
- Potential for social unrest if the outbreak is not effectively managed
Prevention and Control Measures
To combat the spread of mpox, health authorities are implementing various strategies:
Vaccination
While vaccine supplies are limited, targeted vaccination of high-risk groups is being implemented where possible.
Contact Tracing
Identifying and monitoring contacts of confirmed cases is crucial to prevent further spread.
Public Education
Campaigns to educate the public about mpox symptoms, transmission, and prevention are being rolled out across affected countries.
Enhanced Surveillance
Improved disease surveillance systems are being implemented to detect and respond to new cases quickly.
