Monkeypox: Symptoms, Prevention, Vaccine, and Treatment

Table of Contents

What is Monkeypox?

Monkeypox is a viral disease caused by the monkeypox virus, a member of the Orthopoxvirus genus, which also includes the variola virus (the cause of smallpox). It was first discovered in 1958 in monkeys kept for research, hence the name. The first human case was recorded in 1970 in the Democratic Republic of Congo.

Unlike what the name suggests, monkeys are not the primary reservoir of the virus. The natural reservoir remains unknown, but African rodents and non-human primates are suspected to harbor the virus and potentially play a role in its transmission.

Monkeypox is less contagious than smallpox and generally causes a milder illness. However, it’s essential to understand its characteristics, transmission, and prevention methods to minimize its spread and impact on public health. Increased global travel and changing ecological factors contribute to the emergence and re-emergence of zoonotic diseases like monkeypox, making awareness and preparedness crucial.

Monkeypox Symptoms: What to Look For

The symptoms of monkeypox are similar to those of smallpox but are generally milder. The incubation period (the time from infection to symptoms) is typically 7–14 days, but can range from 5–21 days.

Common Symptoms Include:

  • Fever: Often one of the first symptoms to appear.
  • Headache: Can range from mild to severe.
  • Muscle aches (myalgia): Pain and stiffness in the muscles.
  • Backache: Pain in the lower back.
  • Swollen lymph nodes (lymphadenopathy): This is a key distinguishing feature of monkeypox compared to diseases like chickenpox or measles.
  • Exhaustion (asthenia): Feeling tired and weak.
  • Rash: The rash is the most characteristic symptom. It typically starts 1-3 days after the onset of fever. The rash goes through several stages:
  • Macules: Flat, discolored spots.
  • Papules: Raised bumps.
  • Vesicles: Small, fluid-filled blisters.
  • Pustules: Pus-filled blisters.
  • Scabs or crusts: The blisters eventually scab over and fall off.

The rash can appear on the face, inside the mouth, and on other parts of the body, such as the hands, feet, and genitals. The lesions may be itchy or painful.

It’s important to note that symptoms can vary from person to person. Some individuals may experience only a few mild symptoms, while others may have more severe symptoms. If you suspect you may have monkeypox, seek medical attention promptly.

How Monkeypox Spreads: Transmission Routes

Understanding how monkeypox spreads is crucial for preventing its transmission. The virus can spread in several ways:

  • Direct contact: This includes direct contact with the rash, scabs, or bodily fluids of an infected person or animal.
  • Respiratory droplets: Prolonged face-to-face contact is required to spread the virus through respiratory droplets. This is because the droplets are relatively heavy and do not travel far.
  • Contaminated materials: The virus can spread through contact with contaminated materials such as clothing, bedding, or towels used by an infected person.
  • Animal-to-human transmission: This can occur through bites or scratches from infected animals, or through handling wild game.
  • Mother to fetus: Monkeypox can be transmitted from a pregnant woman to her fetus.

Factors that can increase the risk of transmission include:

  • Close contact with an infected individual or animal.
  • Lack of personal protective equipment (PPE) when caring for an infected person.
  • Travel to areas where monkeypox is endemic.

By understanding the different transmission routes, individuals can take appropriate precautions to protect themselves and others.

Monkeypox vs. Chickenpox: Key Differences

Monkeypox and chickenpox are both viral infections that cause rashes, but they have some key differences. Distinguishing between the two can help in seeking appropriate medical care and preventing further spread.

| Feature | Monkeypox | Chickenpox |
| ——————- | ————————————————————————— | —————————————————————————– |
| Causative Agent | Monkeypox virus (Orthopoxvirus genus) | Varicella-zoster virus |
| Lymphadenopathy | Swollen lymph nodes are a prominent feature. | Swollen lymph nodes are less common. |
| Rash Progression | Rash progresses through distinct stages (macules, papules, vesicles, pustules). | Rash appears in crops; lesions are at different stages of development at once. |
| Lesion Appearance | Lesions are typically uniform in appearance and develop at the same rate. | Lesions vary in appearance and appear at different times. |
| Severity | Generally milder than smallpox, but can still cause complications. | Typically mild, but can be more severe in adults and immunocompromised individuals. |
| Transmission | Direct contact, respiratory droplets (prolonged exposure), contaminated materials. | Airborne droplets, direct contact. |

Key Takeaways:

  • Lymphadenopathy: Swollen lymph nodes are a significant indicator of monkeypox.
  • Rash Progression: Monkeypox rash progresses in a consistent pattern, while chickenpox rash appears in crops with lesions at different stages.

If you are unsure whether you have monkeypox or chickenpox, it is best to consult a healthcare professional for proper diagnosis and treatment.

Diagnosing Monkeypox: Tests and Procedures

Diagnosing monkeypox involves a combination of clinical evaluation, laboratory testing, and epidemiological information. Early and accurate diagnosis is critical for implementing appropriate infection control measures and providing timely treatment.

Diagnostic Procedures:

  • Clinical Evaluation: A healthcare provider will assess your symptoms, medical history, and potential exposure risks.
  • Specimen Collection: Samples are collected from skin lesions (fluid or scabs) for laboratory testing.
  • Polymerase Chain Reaction (PCR) testing: PCR is the preferred laboratory test. It detects the presence of monkeypox virus DNA in the sample.
  • Viral Culture: Viral culture involves growing the virus in a laboratory setting. While less common than PCR, it can be used to confirm the diagnosis.
  • Serological Testing: Serological tests detect antibodies against the monkeypox virus in the blood. These tests can help identify past infections but are not as useful for acute diagnoses.

Considerations:

  • It’s important to inform your healthcare provider if you have had close contact with someone who has monkeypox or if you have recently traveled to an area where monkeypox is endemic.
  • Samples should be collected by trained healthcare professionals to minimize the risk of contamination and ensure accurate results.

The diagnosis of monkeypox should be confirmed by laboratory testing. This helps to differentiate it from other diseases with similar symptoms, such as chickenpox, measles, and herpes.

Monkeypox Treatment Options: Antivirals and Supportive Care

Currently, there is no specific treatment for monkeypox. However, antiviral medications developed for smallpox may be used to treat monkeypox in some cases. Treatment focuses on alleviating symptoms, preventing complications, and providing supportive care.

Treatment Approaches:

  • Antiviral Medications: Tecovirimat (TPOXX) is an antiviral drug approved for the treatment of smallpox that has also shown effectiveness against monkeypox. It works by inhibiting the spread of the virus within the body. Brincidofovir (CMX001) is another antiviral that may be considered.
  • Supportive Care: Supportive care is essential for managing symptoms and preventing complications. This includes:
  • Pain Management: Over-the-counter pain relievers can help reduce fever and relieve pain.
  • Wound Care: Keeping the rash clean and dry is important to prevent secondary bacterial infections. Topical antibiotics may be used to treat any secondary infections.
  • Fluid and Electrolyte Balance: Maintaining adequate hydration is crucial, especially if the patient has fever or difficulty eating.
  • Isolation: Infected individuals should be isolated to prevent further spread of the virus.

Considerations:

  • Treatment decisions should be made in consultation with a healthcare professional, considering the severity of the illness and the patient’s overall health.
  • Antiviral medications may not be necessary for mild cases of monkeypox.

Early diagnosis and prompt supportive care can help reduce the severity and duration of monkeypox.

Monkeypox Vaccine: Prevention and Availability

Vaccination is an effective way to prevent monkeypox. Vaccines used for smallpox have been shown to provide protection against monkeypox due to the similarity between the viruses.

Types of Vaccines:

  • JYNNEOS (MVA-BN): This is a newer vaccine approved for the prevention of monkeypox and smallpox. It is a live, non-replicating vaccine, meaning it cannot replicate in the body. This makes it safer for people with weakened immune systems. It is administered in two doses, four weeks apart.
  • ACAM2000: This is an older vaccine approved for smallpox. It is a live, replicating vaccine, which means it can replicate in the body. It is more likely to cause side effects than JYNNEOS and is not recommended for people with weakened immune systems or certain other medical conditions.

Vaccination Strategies:

  • Pre-exposure Prophylaxis (PrEP): Vaccination of individuals at high risk of exposure to monkeypox, such as healthcare workers, laboratory personnel, and those with certain sexual behaviors.
  • Post-exposure Prophylaxis (PEP): Vaccination of individuals who have been exposed to monkeypox. PEP is most effective when administered within 4 days of exposure, but can still provide some protection if given up to 14 days after exposure.

Availability:

The availability of monkeypox vaccines may vary depending on the region and the supply. Public health authorities are working to ensure that vaccines are available to those who need them most. Check with your local health department or healthcare provider for information on vaccine availability and eligibility.

Vaccination is a critical tool in controlling the spread of monkeypox. Staying informed about vaccine availability and eligibility can help protect yourself and your community.

Who is at Risk for Monkeypox?

While anyone can contract monkeypox, certain groups are at higher risk. Understanding these risk factors can help individuals take appropriate precautions.
