 Simple Explanation of Monkeypox:

What is Monkeypox?

• Monkeypox is a disease caused by a virus.
• It can make you feel sick and give you a rash.

How Do You Get It?

• From Animals: You can get it by touching animals that have the virus, like certain rodents.
• From People: You can also get it by touching someone who is sick with monkeypox or their clothes and bedding.

What Are the Symptoms?

• Fever: You might feel very hot.
• Headache: Your head might hurt.
• Muscle Aches: Your body might feel sore.
• Rash: You get red spots on your skin that turn into blisters.

  

How to Stay Safe?

• Avoid Touching: Don’t touch animals or people who are sick.
• Wash Hands: Keep your hands clean by washing them often.
• Use Protection: Wear gloves and masks if you are caring for someone who is sick.

What to Do If You Feel Sick?

• See a Doctor: Go to a health clinic or hospital.
• Stay Away from Others: Try not to be close to other people to avoid spreading the virus.

Smallpox and Monkeypox are Both Viral Diseases Caused by Viruses from the Orthopoxvirus Family, but They Have Some Key Differences:

Smallpox

• Causative Agent: Variola virus.
• Symptoms: High fever, fatigue, severe headache, backache, and a characteristic rash that progresses to pus-filled sores.
• Transmission: Highly contagious, spread through respiratory droplets, direct contact with infected bodily fluids, or contaminated objects.
• Severity: Historically, smallpox had a high mortality rate and caused severe illness.
• Lymphadenopathy: Does not cause swelling of the lymph nodes.
• Eradication: Declared eradicated in 1980 after a successful global vaccination campaign¹.

Monkeypox

• Causative Agent: Monkeypox virus.
• Symptoms: Fever, headache, muscle aches, backache, swollen lymph nodes, chills, and a rash that often begins on the face and spreads to other parts of the body.
• Transmission: Less contagious than smallpox, spread through close contact with infected animals or humans, and respiratory droplets or contact with contaminated materials.
• Severity: Generally milder than smallpox, with a lower mortality rate, but can still cause serious illness.
• Lymphadenopathy: Causes noticeable swelling of the lymph nodes, which is a distinguishing feature from smallpox²³.

Both diseases share some similarities in symptoms, but the presence of swollen lymph nodes in monkeypox and the higher severity and contagiousness of smallpox are key differences.

Monkeypox Has an Intriguing History, Marked by Several Significant Outbreaks and Discoveries:

Initial Discovery

1958: Monkeypox was first identified in laboratory monkeys in Copenhagen, Denmark, during two outbreaks of a pox-like disease12. Despite its name, the primary reservoirs of the virus are believed to be rodents, not monkeys1.

First Human Case

1970: The first human case of monkeypox was recorded in a 9-month-old boy in the Democratic Republic of the Congo (DRC)3. This occurred during intensified efforts to eradicate smallpox, which led to increased surveillance for pox-like illnesses3.

Subsequent Outbreaks

1980s-1990s: Sporadic cases and outbreaks were reported primarily in Central and West African countries, including the DRC, Nigeria, and Cameroon3.

2003: The first outbreak outside of Africa occurred in the United States, linked to imported African rodents that infected pet prairie dogs3. This outbreak resulted in over 70 cases but no fatalities3.

Recent Global Outbreak

2022-2023: A significant global outbreak began in May 2022, with cases reported in multiple non-endemic countries, including Europe and North America13. This outbreak was notable for its rapid spread and the involvement of the West African clade of the virus, which is less severe than the Central African clade3.

Monkeypox’s History Highlights the Importance of Global Surveillance and Preparedness to Manage Emerging Infectious Diseases.

The recent monkeypox outbreak began in early May 2022, with cases reported in countries where the disease is not typically found¹. Most of these cases were linked to travel to Europe and North America, rather than the traditional endemic regions of West and Central Africa¹.

Key Points:

• Initial Cases: The outbreak started with cases in non-endemic countries, primarily in Europe and North America¹.
• Transmission: The virus spread through close contact, including sexual contact, and was identified mainly among men who have sex with men¹.
• Strains: The outbreak involved the West African clade of the monkeypox virus, which is less severe compared to the Central African clade²³.

Recent Developments:

• Central Africa: In 2024, a concerning strain of the monkeypox virus spread rapidly across Central Africa, prompting the Africa Centres for Disease Control and Prevention to declare a public health emergency⁴.

Global Response: The World Health Organization (WHO) has been actively working with health authorities to prevent further spread, providing Monkeypox

• Physical Examination: A thorough examination is conducted, focusing on the characteristic rash and other symptoms like fever, swollen lymph nodes, and muscle aches¹.

Laboratory Testing

• Sample Collection: Samples are taken from skin lesions, including vesicles, pustules, or scabs. These samples are crucial for accurate diagnosis¹².
• Polymerase Chain Reaction (PCR): The primary method for confirming monkeypox is PCR testing, which detects the DNA of the monkeypox virus in the collected samples²³.
• Other Tests: In some cases, additional tests may be performed to rule out other infections with similar symptoms, such as herpes simplex virus, syphilis, or chickenpox¹.

Differential Diagnosis

• Other Conditions: Doctors consider other possible causes of the symptoms, including other poxvirus infections, allergic reactions, and various skin conditions¹.

Importance of Early Diagnosis

• Preventing Spread: Early and accurate diagnosis is essential to prevent the spread of the virus and to provide appropriate care to the infected individual¹.

Monkeypox Can Lead to Several Complications, Some of Which Can Be Severe. The Main Complications Associated with Monkeypox:

Common Complications

• Secondary Infections: Bacterial infections of the skin lesions can occur, leading to further complications¹.
• Bronchopneumonia: Infection of the lungs, which can cause breathing difficulties².
• Sepsis: A life-threatening response to infection that can lead to tissue damage and organ failure².
• Encephalitis: Inflammation of the brain, which can cause neurological symptoms and long-term damage².
• Corneal Infection: Infection of the cornea, which can lead to vision loss².

Other Potential Complications

• Severe Dehydration: Due to vomiting and diarrhoea, which can lead to malnutrition¹.
• Painful Lesions: Lesions in sensitive areas such as the mouth, eyes, and genitalia can cause significant discomfort and complications¹.
• Scarring: Permanent scarring from the skin lesions¹.

Risk Factors for Severe Complications

• Immunocompromised Individuals: People with weakened immune systems are at higher risk of severe complications³.
• Children and Pregnant Women: These groups are more susceptible to severe symptoms and complications³.

Prevention and Management

• Early Diagnosis and Treatment: Prompt medical attention can help manage symptoms and prevent complications¹.
• Vaccination: Vaccines developed for smallpox can also provide protection against monkeypox¹.

Understanding these complications highlights the importance of preventive measures and early medical intervention.

Currently, no specific treatment is approved exclusively for monkeypox. However, several approaches can help manage the symptoms and prevent complications:

Supportive Care

• Symptom Relief: Pain relievers like ibuprofen or acetaminophen can help reduce fever and pain¹.
• Hydration: Drinking plenty of fluids to stay hydrated and maintain electrolyte balance².
• Skin Care: Keeping the rash clean and dry, and avoiding touching the lesions to prevent secondary infections¹.

Antiviral Treatments

• Tecovirimat (TPOXX): An antiviral medication that has shown promise in treating monkeypox. It is available under an expanded access protocol for certain patients, such as those with severe disease or weakened immune systems³.
• Other Antivirals: Research is ongoing to determine the effectiveness of other antiviral drugs in treating monkeypox³.

Preventive Measures

• Isolation: Infected individuals should isolate themselves to prevent spreading the virus to others².
• Vaccination: Vaccines developed for smallpox, such as the JYNNEOS vaccine, can also protect monkeypox³.

Management of Complications

• Secondary Infections: Antibiotics may be prescribed if bacterial infections develop in the skin lesions³.
• Severe Cases: Hospitalization may be required for severe cases, especially for those with complications like encephalitis or sepsis³.

Ongoing Research

• Clinical Trials: Studies are being conducted to evaluate the safety and efficacy of various treatments for monkeypox³.

 

Recovery From Monkeypox Typically Takes Between 2 to 4 Weeks. Here’s a Breakdown of the Recovery Process:

Initial Phase (1-2 Weeks)

• Early Symptoms: Fever, headache, muscle aches, and swollen lymph nodes appear first.
• Rash Development: The rash progresses through stages, starting as flat lesions, then raised bumps, fluid-filled blisters, and finally pus-filled sores.

Healing Phase (2-4 Weeks)

• Scabbing: The sores eventually scab over and begin to heal.
• Falling Off: Scabs fall off, leaving the skin underneath to heal completely.

Factors Influencing Recovery

• Severity of Infection: Milder cases may recover faster, while severe cases might take longer.
• Immune System: Individuals with strong immune systems tend to recover more quickly.
• Complications: The presence of complications like secondary infections can prolong recovery.

Post-Recovery

• Scarring: Some individuals may experience scarring where the lesions are.
• Fatigue: It’s common to feel fatigued even after the visible symptoms have resolved.

Monkeypox and COVID-19 differ significantly in terms of lethality and transmission potential:

Lethality

• Monkeypox: The fatality rate for monkeypox varies between 0% and 11%, depending on the strain and the population affected¹. The recent outbreak in Africa has shown a fatality rate around 3%, with higher rates in certain vulnerable groups¹.
• COVID-19: The fatality rate for COVID-19 has varied widely, influenced by factors such as age, underlying health conditions, and access to medical care. Globally, the case fatality rate has been estimated at around 1-2%, but it has been much higher in older adults and those with pre-existing conditions².

Transmission

• Monkeypox: Primarily spreads through close skin-to-skin contact, respiratory droplets during prolonged face-to-face interaction, and contact with contaminated materials like bedding or clothing³. It does not spread as easily as COVID-19 and is less likely to cause widespread outbreaks³.
• COVID-19: Spreads mainly through respiratory droplets and aerosols, making it highly contagious, especially in crowded or poorly ventilated spaces². Asymptomatic transmission has also played a significant role in its rapid global spread².

Global Spread Potential

• Monkeypox: While monkeypox can spread internationally, its transmission dynamics make it less likely to cause a pandemic on the scale of COVID-19³. The visible symptoms and slower transmission rate help in identifying and isolating cases more effectively⁴.
• COVID-19: The virus’s ability to spread quickly and silently, often before symptoms appear, contributed to its rapid global spread and pandemic status².

In summary, while monkeypox can cause serious illness and has a higher fatality rate in certain populations, it is less likely to spread globally like COVID-19 due to its transmission characteristics.

Countries Vulnerable to Monkeypox Spread

Countries in Central and West Africa are traditionally more vulnerable to monkeypox due to the presence of the virus in local wildlife and the higher likelihood of human-animal interactions. 

Countermeasures to Lessen the Spread

To reduce the chances of monkeypox spreading, several preventive measures can be implemented:

Public Health Measures

• Surveillance and Reporting: Strengthening disease surveillance systems to quickly identify and report cases³.
• Isolation and Quarantine: Isolating infected individuals and quarantining those who have been exposed³.
• Vaccination: Using vaccines like JYNNEOS for high-risk populations, including healthcare workers and those in outbreak areas³.

Personal Protective Measures

• Avoid Close Contact: Refrain from close physical contact with individuals showing symptoms of monkeypox³.
• Hygiene Practices: Regular hand washing with soap and water or using alcohol-based hand sanitizers³.
• Protective Clothing: Wearing gloves and protective clothing when handling animals or caring for infected individuals⁴.
