What is Mpox and How Dangerous is it?

What is Mpox?

Mpox, formerly known as monkeypox, is a viral zoonotic disease, meaning it can be transmitted from animals to humans. The virus was first discovered in 1958 when outbreaks of a pox-like disease occurred in monkeys kept for research in a laboratory in Denmark. However, despite its name, monkeys are not the primary reservoir for the virus. Instead, it is believed that rodents, particularly those native to Central and West Africa, serve as the main hosts for the virus.

The first human case of mpox was recorded in 1970 in the Democratic Republic of Congo (DRC). Since then, the virus has been identified in several other African countries, with occasional outbreaks in other parts of the world. In 2022, the World Health Organization (WHO) renamed the virus to “mpox” to reduce the stigma associated with its previous name.

What Are the Symptoms of Mpox?

Mpox symptoms can range from mild to severe and typically appear 6-13 days after exposure to the virus, though the incubation period can vary between 5 and 21 days. Early symptoms resemble those of other viral infections and include:

• Fever
• Headache
• Muscle aches
• Back pain
• Fatigue
• Swollen lymph nodes

A few days after the onset of these symptoms, patients typically develop a rash that progresses through several stages. The rash begins as flat, red spots that eventually evolve into raised bumps, filled with clear fluid, and then pus. These bumps can be painful and may occur anywhere on the body, including the face, hands, feet, and genital area. In some cases, the rash may also develop inside the mouth, making it difficult to eat or drink.

The rash typically lasts for about 2-4 weeks before the bumps scab over and fall off, leaving scars that may be permanent. While most people recover fully, the disease can be severe, especially in children, pregnant women, and individuals with weakened immune systems.

Why is Mpox Spreading Rapidly?

In recent years, there has been a notable increase in mpox cases outside of Africa, raising concerns among global health officials. Several factors contribute to the more rapid spread of the virus:

1. Mutations in the Virus: Recent genetic analyses suggest that the mpox virus has undergone several mutations that may have made it more efficient at spreading from person to person. Some of these mutations could potentially help the virus evade the human immune system, increasing its transmissibility.
2. Global Travel: The rise in international travel has facilitated the spread of mpox. Infected individuals may unknowingly carry the virus to other parts of the world, leading to new outbreaks in regions where the virus is not endemic.
3. Decreased Immunity: The global cessation of smallpox vaccinations in the 1980s has resulted in decreased immunity to poxviruses in the general population. Since the smallpox vaccine also provides protection against mpox, the end of widespread vaccination campaigns has left many people vulnerable to the virus.
4. Urbanization and Deforestation: As human populations expand into previously uninhabited areas, the likelihood of contact with infected animals increases. Deforestation and urbanization have brought humans into closer proximity with wildlife that may carry the virus, increasing the risk of zoonotic transmission.

Where Did Mpox Come From?

The exact origins of mpox are not entirely understood, but it is believed that the virus has been circulating in rodent populations in Central and West Africa for centuries. The virus likely spills over to humans through direct contact with infected animals, such as through hunting, handling, or consuming bushmeat.

The first documented human case occurred in 1970 in the DRC, but it is likely that the virus had been infecting people for much longer without being recognized. The virus is part of the Orthopoxvirus genus, which also includes smallpox, cowpox, and vaccinia viruses. Like these other poxviruses, mpox is a double-stranded DNA virus, making it relatively stable and less prone to mutation compared to RNA viruses like the one that causes COVID-19.

How Does Mpox Spread?

Mpox primarily spreads through close contact with an infected person or animal. The virus can be transmitted through direct contact with bodily fluids, such as blood, saliva, or respiratory droplets, as well as through contact with the rash, scabs, or bedding and clothing contaminated by an infected person.

Although mpox is not as easily transmissible as some other viruses, such as COVID-19, it can still spread through prolonged close contact, making it a concern in households, healthcare settings, and communities where people are in close proximity.

There has also been some evidence to suggest that the virus can be transmitted through sexual contact, although it is not yet clear whether this is a primary mode of transmission. The majority of cases reported in the 2022 outbreaks in the US and Europe occurred among men who have sex with men, but the virus can infect anyone, regardless of sexual orientation.

How Dangerous is Mpox?

The severity of mpox can vary depending on several factors, including the strain of the virus, the patient’s age, and their overall health. There are two main clades (or strains) of the virus: Clade I (formerly known as the Congo Basin clade) and Clade II (formerly known as the West African clade). Clade I is more virulent, with a mortality rate of up to 10%, while Clade II has a lower mortality rate of around 1-3%.

While most cases of mpox are mild and resolve without the need for medical treatment, the disease can be severe and even fatal in some cases. Children, pregnant women, and individuals with compromised immune systems are at higher risk of developing serious complications, such as secondary bacterial infections, pneumonia, or sepsis.

Additionally, the painful lesions caused by the virus can lead to long-term scarring and disfigurement, especially if the rash is extensive or becomes infected.

Why Did Mpox Become a Global Health Emergency?

The resurgence of mpox and its spread to non-endemic regions prompted global health authorities to declare it a public health emergency of international concern. Several factors contributed to this decision:

1. Rapid Spread: The speed at which the virus spread across multiple continents, particularly in the 2022-2024 outbreaks, alarmed health officials. The emergence of new variants of the virus, including Clade Ib, which appears to spread more easily, further heightened concerns.
2. Lack of Immunity: As mentioned earlier, the cessation of smallpox vaccinations has left a significant portion of the global population without immunity to poxviruses, increasing the risk of widespread outbreaks.
3. Potential for Severe Disease: Although mpox is generally less deadly than smallpox, it can still cause severe illness and death, particularly in vulnerable populations. The possibility of the virus evolving into more virulent forms or spreading to new regions where it could become endemic is a significant concern.
4. Global Health Inequities: The global response to mpox highlighted disparities in healthcare resources and access to vaccines and treatments. While wealthy nations were able to quickly deploy vaccines and antiviral medications, many African countries where the virus is endemic struggled to access these critical resources.
5. Zoonotic Potential: Mpox is a zoonotic disease, meaning it can jump from animals to humans and vice versa. The potential for the virus to establish itself in new animal populations outside of Africa, where it could continue to spill over into human populations, is a significant concern for global health security.

Why is it Called Monkey Pox?

Monkeypox got its name in 1958 after the virus was first identified in monkeys used for research. However, monkeys are not the main carriers of the virus; it primarily affects rodents. The name persisted even though the first human case wasn’t recorded until 1970 in the Democratic Republic of Congo. To reduce confusion and stigma, the World Health Organization (WHO) later renamed the virus “mpox.”

The Ongoing Challenge of Mpox

Mpox has re-emerged as a global health threat, underscoring the importance of vigilant monitoring, rapid response, and equitable access to healthcare resources. While the virus has been known for decades, its recent spread and the emergence of new variants have highlighted the challenges of controlling zoonotic diseases in an interconnected world.

Efforts to combat mpox will require a coordinated global response, including increased surveillance, public health education, and the development of new vaccines and treatments. The lessons learned from the COVID-19 pandemic and the ongoing mpox outbreaks emphasize the need for preparedness and resilience in the face of emerging infectious diseases.
