Mpox Explained: History, Spread, Prevention, and Key Do's and Don'ts for Staying Safe

Introduction

Mpox, formerly known as monkeypox, is a viral disease that has garnered global attention due to its re-emergence in various parts of the world. Although it was initially discovered in monkeys, it primarily affects humans and has led to several outbreaks over the past few decades. Understanding the origin, history, spread, and prevention of mpox is crucial not only for public health professionals but also for the general public, who play a key role in curbing its transmission. In this blog, we will delve into the history of mpox, explore how it spreads, discuss prevention strategies, and provide a balanced perspective on whether to worry or stay calm.

Origin and History of Mpox

Origin

Mpox was first identified in 1958 when outbreaks occurred in laboratory monkeys that were being used for research, hence the name "monkeypox." However, the virus is not exclusive to monkeys; it is primarily found in rodents and other small mammals. The first human case of mpox was reported in 1970 in the Democratic Republic of the Congo (DRC), during a period of intensified effort to eliminate smallpox. The virus belongs to the Orthopoxvirus genus, which also includes the variola virus (smallpox) and the vaccinia virus (used in the smallpox vaccine).

The initial human cases were mostly confined to the rainforest regions of Central and West Africa, where the virus is considered endemic. The exact reservoir of the virus remains uncertain, although it is believed that certain species of squirrels, rats, and other rodents play a significant role in its transmission to humans. The zoonotic nature of the virus—meaning it can be transmitted from animals to humans—places people who live in close proximity to these animals at greater risk, particularly in regions where hunting and consumption of bushmeat are common.

History

Since its discovery, mpox has caused several notable outbreaks, predominantly in Africa. The early cases reported in the 1970s and 1980s were relatively small and limited to rural areas. However, as the world became more connected through travel and trade, the virus started appearing in regions far beyond its endemic areas.

The first significant outbreak outside of Africa occurred in the United States in 2003. This outbreak was traced back to imported Gambian pouched rats from West Africa, which were housed with prairie dogs and sold as pets. The virus spread to humans through these infected animals, leading to more than 70 confirmed cases. Fortunately, there were no fatalities, but the incident highlighted the potential for mpox to spread beyond its traditional boundaries.

In the years following the 2003 outbreak, sporadic cases continued to be reported in Africa, but the world’s attention was primarily focused on other emerging diseases such as Ebola and Zika. It wasn't until the 2020s that mpox once again captured global headlines, as cases began appearing in Europe, North America, and other regions far removed from its endemic zones. The re-emergence of mpox in non-endemic countries in 2022 was particularly alarming, as it suggested the virus might be spreading in ways not previously understood, possibly through human-to-human transmission in densely populated areas.

Global Spread

The spread of mpox from its original endemic regions in Africa to other parts of the world is a concerning development in global public health. The 2022 outbreaks, which occurred simultaneously in multiple countries, raised questions about the effectiveness of current containment strategies and the potential for the virus to establish itself in new regions.

The spread of mpox can be attributed to several factors, including increased global travel, changing environmental conditions, and the movement of animals through trade. As people travel between regions, they may unknowingly carry the virus with them, leading to new outbreaks in previously unaffected areas. Additionally, the international trade of exotic pets can introduce the virus to new ecosystems, where it may find new hosts.

Despite these challenges, efforts to control the spread of mpox have been largely successful, thanks in part to lessons learned from past outbreaks and the global community's experience with handling zoonotic diseases. However, the continued spread of the virus highlights the need for vigilance and preparedness in the face of emerging infectious diseases.

How Mpox Spreads

Transmission Mechanisms

Mpox is primarily spread through direct contact with the blood, bodily fluids, or skin lesions of infected animals or humans. The virus can enter the body through broken skin, respiratory tract, or mucous membranes (eyes, nose, mouth). Human-to-human transmission is possible but less common and usually occurs through prolonged close contact, including respiratory droplets during face-to-face interactions, direct contact with skin lesions, or contaminated materials such as bedding or clothing.

In the natural environment, the virus circulates among various animal species, particularly rodents, which are believed to be the primary reservoir. Humans can become infected by handling infected animals or consuming undercooked meat from these animals. In regions where hunting and bushmeat consumption are common, the risk of transmission from animals to humans is significantly higher.

Role of Travel and Globalization

The spread of mpox to non-endemic regions can be directly linked to globalization and increased international travel. In the past, the virus was largely contained within isolated communities in Africa, where it circulated among wildlife and occasionally spilled over into the human population. However, with the advent of air travel and global trade, the potential for diseases to cross borders has increased exponentially.

The 2022 outbreak, for instance, saw cases reported in multiple countries across Europe, North America, and Asia, often with no clear link to travel in endemic regions. This pattern suggests that the virus may have been spreading unnoticed for some time, facilitated by global movement and possibly even person-to-person transmission in densely populated urban areas.

Environmental Factors

Environmental factors also play a significant role in the spread of mpox. Changes in land use, deforestation, and urbanization have brought humans into closer contact with wildlife, increasing the likelihood of zoonotic spillover events. In Africa, where the virus is endemic, deforestation and agricultural expansion have disrupted natural habitats, forcing wildlife to encroach on human settlements. This proximity facilitates the transmission of viruses from animals to humans.

Climate change is another factor that could influence the spread of mpox. Alterations in temperature and precipitation patterns can affect the distribution and behavior of wildlife, potentially leading to new opportunities for virus transmission. Additionally, extreme weather events can displace populations, leading to increased contact between humans and animals and raising the risk of outbreaks.

Prevention Strategies

Vaccination

One of the most effective ways to prevent mpox is through vaccination. The smallpox vaccine, which was widely used during the global campaign to eradicate smallpox, provides cross-protection against mpox due to the close genetic relationship between the two viruses. Individuals who were vaccinated against smallpox are believed to have some level of immunity against mpox.

In response to the recent outbreaks, some countries have initiated targeted vaccination campaigns using newer, safer vaccines that are specifically designed to protect against mpox. These vaccines, such as the MVA-BN vaccine, are derived from modified vaccinia virus and have been shown to be effective in preventing mpox in both pre-exposure and post-exposure settings.

Public health authorities have prioritized vaccination for high-risk groups, including healthcare workers, laboratory personnel, and individuals who have been in close contact with confirmed cases. However, the availability and distribution of vaccines remain challenges, particularly in low-resource settings where the virus is endemic.

Hygiene Practices

In addition to vaccination, maintaining good hygiene practices is crucial in preventing the spread of mpox. This includes regular handwashing with soap and water, avoiding contact with animals that could be infected, and practicing safe food handling, especially when dealing with meat from wild animals.

For those living in or traveling to areas where mpox is endemic, it is important to avoid close contact with animals, particularly rodents and non-human primates. If contact with animals is unavoidable, wearing protective clothing and using insect repellent can reduce the risk of exposure.

In the event of an outbreak, public health authorities may recommend additional measures such as the use of personal protective equipment (PPE) and the disinfection of contaminated surfaces. Isolating infected individuals and practicing social distancing can also help to limit the spread of the virus.

Public Awareness

Raising public awareness about mpox is essential in preventing its spread. Education campaigns should focus on informing communities about the symptoms of mpox, the importance of early diagnosis and treatment, and the steps they can take to protect themselves and others.

In many endemic regions, there is a need for better communication strategies to reach remote and underserved populations. This includes using local languages and culturally appropriate messaging to ensure that information is accessible and actionable.

For the global community, awareness campaigns should emphasize the importance of travel precautions, especially for individuals visiting areas where mpox is prevalent. Travelers should be advised to avoid contact with wildlife, practice good hygiene, and seek medical attention if they develop symptoms after returning home.

Reasons to Worry vs. Reasons to Relax

Reasons to Worry

While mpox is not as contagious as some other infectious diseases, there are still valid reasons for concern. The potential for severe outbreaks, particularly in regions with limited healthcare infrastructure, poses a significant public health risk. Mpox can cause severe illness, especially in children, pregnant women, and individuals with weakened immune systems. In some cases, the virus can lead to complications such as secondary bacterial infections, respiratory distress, and even death.

Another reason to worry is the possibility of the virus mutating and becoming more transmissible or resistant to existing treatments. While there is currently no evidence of such mutations, the rapid spread of mpox in non-endemic regions has raised questions about the virus's evolution and adaptability. Continuous monitoring and research are needed to understand these risks better.

Moreover, the stigma associated with mpox can hinder efforts to control outbreaks. Misinformation and fear can lead to discrimination against affected individuals and communities, making it more difficult to identify and treat cases. Public health authorities must address these social challenges alongside the biological and medical aspects of the disease.

Reasons to Relax

Despite these concerns, there are several reasons to remain optimistic. First, the transmission rate of mpox is relatively low compared to other infectious diseases such as COVID-19 or influenza. Mpox requires close contact for transmission, making it less likely to spread rapidly through large populations.

Second, effective treatments and vaccines are available. The smallpox vaccine has proven to be effective in preventing mpox, and newer vaccines are being developed and distributed. Antiviral treatments, such as tecovirimat, have also shown promise in treating mpox cases, particularly in severe or complicated infections.

Furthermore, the survival rate for mpox is high, especially with prompt medical care. Most individuals who contract the virus experience mild to moderate symptoms and recover fully within a few weeks. The case fatality rate is much lower than that of diseases like Ebola, providing some reassurance that, while serious, mpox is not a death sentence for the vast majority of those affected.

Lastly, global health organizations, governments, and scientific communities are actively working together to monitor and control the spread of mpox. Lessons learned from the COVID-19 pandemic have improved the world's ability to respond to emerging infectious diseases, including mpox. With continued vigilance and cooperation, the risks posed by mpox can be effectively managed.
