Mpox Virus Explained: Early Symptoms, Risk Factors & Latest Treatment

Overview

Mpox (formerly known as monkeypox) is a viral infectious disease caused by the monkeypox virus, belonging to the Orthopoxvirus family. It can cause a painful rash, fever, swollen lymph nodes, and other flu-like symptoms.

While most people recover within a few weeks, some cases can become severe, especially in high-risk individuals.

Key Facts About Mpox

• Mpox is caused by the monkeypox virus (MPXV).

• It has two main clades:

  Clade I (Ia & Ib) – more severe
• Clade II (IIa & IIb) – responsible for the 2022–2023 global outbreak
• The disease is still spreading in some regions, especially in Africa.
• Vaccines are available and can help prevent infection.
• Symptoms usually last 2–4 weeks.

Causes of Mpox

Mpox is caused by a double-stranded DNA virus from the Poxviridae family, which also includes:

• Smallpox (Variola virus)
• Cowpox
• Vaccinia virus

The natural host of the virus is not fully known, but it is found in:

• Rodents (like squirrels)
• Primates (like monkeys)

Transmission (How Mpox Spreads)

Person-to-Person Spread

Mpox spreads mainly through close contact, including:

• Skin-to-skin contact (touching, sexual contact)
• Kissing or mouth-to-skin contact
• Face-to-face interaction (talking closely, breathing droplets)

Other Ways of Transmission

• Contact with contaminated items:
• Clothes
• Bedding
• Towels
• Needle injuries (in healthcare settings)

• From mother to baby:

  During pregnancy
• During or after birth

Animal-to-Human Transmission

• Animal bites or scratches
• Handling infected animals
• Eating undercooked meat

Symptoms of Mpox

Symptoms usually appear within 1 to 21 days after exposure.

Common Symptoms

• Skin rash
• Fever
• Headache
• Muscle aches
• Back pain
• Low energy (fatigue)
• Swollen lymph nodes
• Sore throat

Rash Characteristics

• Can appear on:
• Hands and feet
• Face and mouth
• Genitals and anus

• Progression:

• Flat spots → Blisters → Scabs → Healing

Additional Symptoms

• Pain while swallowing
• Difficulty urinating (dysuria)
• Rectal pain (proctitis)

Complications of Mpox

In severe cases, Mpox may lead to:

• Secondary skin infections
• Pneumonia
• Vision loss (eye infection)
• Dehydration
• Sepsis (blood infection)
• Brain inflammation (encephalitis)
• Heart inflammation (myocarditis)

High-risk groups include:

• Children
• Pregnant women
• People with weak immune systems (e.g., HIV patients)

Diagnosis of Mpox

Mpox can be confused with other diseases like:

• Chickenpox
• Measles
• Herpes
• Syphilis
• Scabies

Testing Method

• PCR test (Polymerase Chain Reaction) is the most reliable

• Samples are taken from:

  Skin lesions
• Fluid from blisters
• Scabs

Blood tests are not recommended for diagnosis.

Treatment of Mpox

There is no specific cure, but treatment focuses on symptom management.

Supportive Care Includes:

• Pain relief (Paracetamol, Ibuprofen)
• Hydration
• Proper nutrition
• Skin care
• Preventing secondary infections

Important Notes

• Some antiviral drugs are under study
• HIV patients should continue antiretroviral therapy (ART)

Mpox Vaccination

Vaccines are available and recommended for high-risk individuals.

Who Should Get Vaccinated?

• Healthcare workers
• Close contacts of infected individuals
• People with multiple sexual partners
• Sex workers

Types of Protection

• Pre-exposure vaccination (before contact)
• Post-exposure vaccination (within 4–14 days after contact)

Prevention Tips

Do’s

• Stay isolated if infected
• Wash hands regularly
• Wear a mask around others
• Keep rash clean and dry
• Use saltwater rinses for mouth sores
• Take warm baths with Epsom salt or baking soda

Don’ts

• Do not scratch or pop blisters
• Avoid shaving affected areas
• Avoid close contact with others

Self-Care at Home

Most people recover within 2–4 weeks. Follow these steps:

• Stay in a well-ventilated room
• Avoid sharing personal items
• Clean surfaces regularly
• Cover lesions when around others

Prevention During Recovery

• Avoid sexual contact during infection
• Use condoms for 12 weeks after recovery
• Monitor symptoms for 21 days after exposure

History & Outbreaks

• First discovered in 1958 in Denmark
• First human case recorded in 1970 (Congo)
• Increased after smallpox vaccination ended in 1980

• Major outbreaks:

  2003 (USA) – linked to animals
• 2017 (Nigeria) – re-emergence
• 2022–2023 (Global) – Clade IIb outbreak

Conclusion

Mpox remains a global health concern, but awareness, vaccination, and proper hygiene can significantly reduce the risk. Early detection and supportive care are key to preventing complications and controlling its spread.
