Who is the carrier of monkeypox?

Introduction to Monkeypox Carriers

The monkeypox virus, an orthopoxvirus closely related to the variola virus, the cause of smallpox, has seen a resurgence in recent years, prompting global health concerns. Commonly referred to as Mpox, this viral infection can manifest through a range of symptoms, from mild rashes to severe complications. Understanding the various carriers of monkeypox is crucial for mitigating its spread and ensuring public health safety. This article delves into the different vectors of monkeypox transmission, categorizing them into human-to-human, environmental, sexual, and animal carriers.

Human Transmission: Close Contacts

● Skin-to-Skin Contact

One of the primary modes of monkeypox virus transmission is through direct skin-to-skin contact. Individuals infected with monkeypox develop lesions that contain a high viral load. These lesions, much like those observed in smallpox, can be highly infectious. Close physical interactions, such as touching or hugging someone with monkeypox, facilitate the transfer of the virus.

● Mouth-to-Mouth and Face-to-Face Interactions

Apart from skin-to-skin contact, face-to-face interactions can also lead to the spread of monkeypox. Activities like kissing or even close conversations can disseminate respiratory droplets, which can carry the virus. The 2022 outbreak notably demonstrated that mouth-to-mouth contact was a significant vector for spreading the virus among close contacts.

Environmental Transmission: Contaminated Objects

● Clothing, Bedding, and Towels

The monkeypox virus is resilient and can survive on various surfaces for extended periods. Contaminated objects, such as clothing and bedding that have come into contact with an infected individual, serve as potential sources of infection. This form of transmission is particularly concerning in shared living spaces or healthcare facilities.

● Electronic Devices and Surfaces

In addition to textiles, electronic devices and other surfaces can harbor the monkeypox virus. Shared gadgets like mobile phones, laptops, and communal surfaces in public areas or homes can become inadvertent carriers of the virus. Consequently, stringent hygiene practices, including regular cleaning and disinfecting, are essential to curb environmental transmission.

Sexual Transmission and Risk Groups

● High-Risk Populations: MSM (Men Who Have Sex With Men)

During the recent outbreaks, the virus predominantly spread within sexual networks, particularly among men who have sex with men (MSM). This demographic has shown higher infection rates, underlining the virus's potential to spread through intimate physical contact. While the virus is not classified as a sexually transmitted infection per se, sexual activities often involve close contact conducive to viral transmission.

● Multi-Partner Sexual Networks

Individuals engaged in multi-partner sexual networks are at heightened risk of contracting monkeypox. The virus can spread swiftly within these networks, especially if preventive measures are not observed. Public health campaigns targeting these communities are crucial for awareness and prevention.

Animal Transmission: Wild and Domestic Animals

● Wild Animal Carriers: Monkeys and Rodents

Monkeypox is named after its initial discovery in laboratory monkeys, but its natural reservoirs include various wild animals, particularly rodents. Species such as tree squirrels and Gambian pouched rats are known carriers. Human infections can result from direct contact with these animals or their bodily fluids, often through bites, scratches, or handling during hunting and food preparation activities.

● Pets and Possible Domestic Transmission

There have been isolated reports of pets, such as dogs, contracting monkeypox, likely through close contact with infected humans. While the evidence is scant, the potential for domestic animals to act as carriers necessitates caution, especially in households with confirmed or suspected monkeypox cases.

Human Behavioral Risks and Mpox Spread

● Hunting, Skinning, and Handling Wild Animals

Human activities, particularly in regions where monkeypox is endemic, contribute significantly to the virus's spread. Hunting, skinning, and handling wild animals expose individuals to potential infection. These practices, prevalent in several African regions, underscore the need for education and protective measures to prevent zoonotic transmission.

● Food Safety: Cooking Contaminated Meat

Consuming undercooked meat from infected animals is another risk factor for monkeypox. The virus can survive in meat that has not been cooked thoroughly, posing a risk to those handling or consuming it. Proper food safety practices, including adequate cooking temperatures, are vital to prevent infection.

Medical and Care Settings: Health Worker Protection

● Infection Control Measures in Healthcare

Healthcare workers are on the front lines of managing monkeypox outbreaks. Protecting these workers involves stringent infection control measures, such as the use of personal protective equipment (PPE), proper hand hygiene, and protocols for handling diagnostic samples. Ensuring the safety of healthcare workers is paramount to controlling the spread within medical facilities.

● Protocols for Treating Mpox Patients

Treating monkeypox patients requires specific protocols to minimize transmission risks. Patients with confirmed or suspected monkeypox should be isolated, and healthcare providers must follow detailed guidelines for swabbing lesions, handling sharps, and disposing of contaminated materials. Compliance with these protocols helps prevent nosocomial infections.

Preventive Measures and Public Awareness

● Steps to Reduce Risk of Infection

Preventing monkeypox transmission involves a multifaceted approach. Public health authorities must educate communities about the virus, its symptoms, and transmission modes. Simple yet effective measures, such as frequent handwashing, avoiding close contact with infected individuals, and following quarantine protocols, are crucial in mitigating the spread.

● Education and Community Engagement

Raising awareness through targeted campaigns, especially in high-risk communities, is essential. Engaging community leaders, healthcare professionals, and public figures can amplify the reach and impact of preventive messages. Public health advice tailored to specific groups, such as sex workers and MSM, can significantly reduce infection rates.

Potential for Asymptomatic Transmission

● Cases of Transmission Without Symptoms

Though rare, there have been instances of asymptomatic transmission, where individuals carry and spread the monkeypox virus without showing symptoms. This mode of transmission complicates containment efforts, as individuals unaware of their infectious status can inadvertently spread the virus.

● Limited Data and Areas for Further Research

The potential for asymptomatic transmission highlights the need for continued research. Expanding our understanding of how the virus operates in asymptomatic carriers, and identifying effective screening methods, are critical for better managing and containing outbreaks.

Global Health Monitoring and Collaboration

● WHO’s Role and International Health Regulations

The World Health Organization (WHO) plays a pivotal role in monitoring monkeypox outbreaks and coordinating international responses. Through the International Health Regulations (IHR), WHO facilitates information sharing, resource allocation, and collaborative efforts to manage and contain outbreaks.

● Collaboration with FAO and WOAH for Animal Health

In addition to human health, WHO collaborates with partners like the Food and Agriculture Organization (FAO) and the World Organisation for Animal Health (WOAH) to address monkeypox in animal populations. These collaborations aim to understand the virus's natural reservoirs and reduce zoonotic transmission risks.
