Monkeypox: Symptoms, Treatment, Prevention & Vaccine Info

Table of Contents

What is Monkeypox?

Monkeypox is a viral disease that belongs to the orthopoxvirus genus, which includes variola virus (the cause of smallpox), vaccinia virus (used in the smallpox vaccine), and cowpox virus. It was first discovered in 1958 when two outbreaks of a pox-like disease occurred in colonies of monkeys kept for research, hence the name “monkeypox.” The first human case was recorded in 1970 in the Democratic Republic of Congo.

Monkeypox is a zoonotic disease, meaning it can spread from animals to humans. The exact animal reservoir for monkeypox remains unknown, though African rodents are suspected. The virus can also spread from person to person, although this is less common than animal-to-human transmission.

Understanding the nature of monkeypox, its origins, and how it spreads is crucial for implementing effective prevention and control measures. This guide will provide comprehensive information about the virus, its symptoms, treatment, and prevention strategies.

Monkeypox vs. Chickenpox: Key Differences

While both monkeypox and chickenpox cause a rash, several key differences distinguish the two diseases. Understanding these distinctions is crucial for proper diagnosis and management.

• Cause: Monkeypox is caused by the monkeypox virus, while chickenpox is caused by the varicella-zoster virus.
• Symptoms:
• Monkeypox: Often begins with flu-like symptoms, such as fever, headache, muscle aches, and swollen lymph nodes, followed by a rash that develops into lesions that progress through stages (macules, papules, vesicles, pustules, scabs).
• Chickenpox: Typically starts with a rash that appears as small, itchy blisters all over the body. Fever and fatigue may also be present, but swollen lymph nodes are less common.
• Lymph Nodes: Swollen lymph nodes (lymphadenopathy) are a characteristic symptom of monkeypox, but they are not typically associated with chickenpox.
• Rash Progression: The monkeypox rash tends to develop in a more sequential and uniform pattern, with lesions progressing through the same stages at a similar rate. Chickenpox lesions, on the other hand, often appear in crops, with lesions in various stages of development.
• Severity: Monkeypox is generally considered more severe than chickenpox, with a higher risk of complications and, in some cases, death.

Recognizing these differences is essential for seeking appropriate medical care and preventing the spread of either disease.

Symptoms of Monkeypox

Monkeypox symptoms typically appear within 5 to 21 days after exposure. The illness often begins with flu-like symptoms, followed by a characteristic rash.

• Initial Symptoms (Prodrome):
• Fever
• Headache
• Muscle aches
• Backache
• Swollen lymph nodes (lymphadenopathy) – a key distinguishing feature from chickenpox
• Exhaustion
• Rash:
• Usually starts within 1-3 days after the onset of fever.
• Begins as flat, discolored spots (macules).
• Progresses to raised bumps (papules).
• Develops into small blisters filled with clear fluid (vesicles).
• Turns into blisters filled with pus (pustules).
• Eventually, the pustules scab over and fall off.
• The rash can appear on the face, inside the mouth, on the hands and feet, and in the genital area.

The lesions typically go through all stages before crusting and falling off. The illness usually lasts 2-4 weeks. It’s important to note that some individuals may experience milder symptoms or only develop the rash, making diagnosis challenging.

How Monkeypox Spreads: Transmission and Risk Factors

Understanding how monkeypox spreads is critical for implementing effective prevention strategies. The virus can be transmitted in several ways:

• Animal-to-Human Transmission (Zoonotic):
• Through direct contact with infected animals, such as rodents and primates.
• By consuming improperly cooked meat from infected animals.
• Through bites or scratches from infected animals.
• Human-to-Human Transmission:
• Through close, direct contact with infectious lesions, scabs, or body fluids.
• Through respiratory droplets during prolonged face-to-face contact.
• Through contact with contaminated materials, such as clothing, bedding, or surfaces.
• Risk Factors:
• Close contact with someone infected with monkeypox.
• Travel to areas where monkeypox is endemic.
• Contact with animals that may harbor the virus.
• Weakened immune system.

It’s important to note that while monkeypox can spread through respiratory droplets, it is not as easily transmitted as viruses like influenza or COVID-19, which require less prolonged contact.

Diagnosing Monkeypox: What to Expect

Diagnosing monkeypox typically involves a combination of clinical evaluation and laboratory testing. If you suspect you have monkeypox, it’s essential to seek medical attention promptly.

• Clinical Evaluation: Your healthcare provider will:
• Ask about your symptoms, including the timeline of their onset and progression.
• Inquire about potential exposures, such as contact with infected individuals or travel to endemic areas.
• Examine your rash and any other symptoms.
• Laboratory Testing: The most common method for confirming monkeypox is through polymerase chain reaction (PCR) testing:
• A sample is collected from a lesion (usually a swab of a skin lesion or fluid from a blister).
• The sample is sent to a specialized laboratory for testing.
• PCR testing detects the presence of the monkeypox virus’s DNA.
• Other tests, such as viral culture, may also be performed, but PCR is generally preferred due to its speed and accuracy.
• Differential Diagnosis: It’s important to rule out other conditions that can cause similar symptoms, such as:
• Chickenpox
• Measles
• Herpes
• Syphilis

Early and accurate diagnosis is crucial for initiating appropriate treatment and preventing further spread of the virus.

Monkeypox Treatment Options and Recovery

Most people with monkeypox experience a mild illness and recover without specific treatment. However, supportive care is important to manage symptoms and prevent complications. In more severe cases, antiviral medications may be considered.

• Supportive Care:
• Pain management: Over-the-counter pain relievers can help alleviate fever, headache, and muscle aches.
• Hydration: Drinking plenty of fluids is important to prevent dehydration.
• Skin care: Keeping the rash clean and dry can help prevent secondary bacterial infections. Avoid scratching the lesions.
• Isolation: Isolating yourself from others until the rash has fully healed is crucial to prevent the spread of the virus.
• Antiviral Medications:
• Tecovirimat (Tpoxx): This antiviral medication has been approved for the treatment of smallpox and is also effective against monkeypox. It works by inhibiting the spread of the virus within the body. Tecovirimat is typically reserved for severe cases or individuals at high risk of complications.
• Other antivirals: Other antiviral medications, such as brincidofovir and cidofovir, may be considered in certain situations, but their use is less common due to potential side effects.
• Recovery:
• The recovery period varies, but most people recover within 2-4 weeks.
• You are considered no longer contagious when all lesions have scabbed over, the scabs have fallen off, and new skin has formed.

Close monitoring by a healthcare provider is important to ensure proper management of symptoms and to address any potential complications.

Monkeypox Vaccine: Availability and Efficacy

A vaccine is available to protect against monkeypox. The JYNNEOS vaccine is a modified vaccinia Ankara (MVA) vaccine, which means it’s a live, attenuated (weakened) virus vaccine. It’s approved for the prevention of both smallpox and monkeypox.

• Availability:
• The JYNNEOS vaccine is currently available in limited quantities.
• Vaccination efforts are primarily focused on individuals at high risk of exposure, such as:
• Close contacts of confirmed cases
• Healthcare workers
• Laboratory personnel who handle orthopoxviruses
• Men who have sex with men and have multiple or anonymous partners in areas with known monkeypox spread.
• Efficacy:
• Studies have shown that the JYNNEOS vaccine is highly effective in preventing monkeypox.
• Vaccination can also reduce the severity of illness in those who do contract the virus.
• The vaccine is administered in two doses, given 28 days apart.
• Considerations:
• Like all vaccines, the JYNNEOS vaccine can cause side effects, such as pain, redness, and swelling at the injection site. Serious side effects are rare.
• The vaccine is not recommended for everyone. Your healthcare provider can help you determine if vaccination is right for you.

Vaccination is an important tool in controlling the spread of monkeypox, particularly among high-risk groups.
