Mpox: An Updated Overview of the Global Outbreak
Published: 2026/02/01 16:18:35
What is Mpox?
Mpox, formerly known as monkeypox, is a viral disease caused by the orthopoxvirus family of viruses [[2]]. While historically found primarily in parts of Central and West Africa, mpox has experienced outbreaks globally, most notably in 2022-2023.The virus spreads through close contact with someone who has mpox,and can cause a painful rash,enlarged lymph nodes,and fever [[1]].
Understanding the Two Clades
The mpox virus has two distinct genetic clades: Clade I and Clade II [[3]]. Clade II, specifically subclade IIb, was responsible for the widespread global outbreak in 2022-2023. Understanding these clades is crucial for tracking the virus’s evolution and tailoring public health responses.
Current Situation: A Public health Emergency
As of August 14, 2024, an upsurge of mpox in the Democratic Republic of the Congo and its spread to neighboring countries was declared a public health emergency of international concern [[1]]. While the global emergency status may have evolved as than, mpox remains a significant public health concern, and ongoing vigilance is essential.
Symptoms of Mpox
The symptoms of mpox typically begin with:
- Fever
- headache
- Muscle aches
- Swollen lymph nodes
Within one to three days after the fever starts, a rash typically appears. This rash can look like pimples or blisters and may appear on the face,palms of the hands,soles of the feet,mouth,or genitals [[2]]. The illness typically lasts for 2-4 weeks.
How Mpox Spreads
Mpox spreads primarily through:
- Direct contact with the rash of someone who has mpox.
- Contact with objects, fabrics (clothing, bedding, towels), and surfaces that have been in contact with the rash.
- Close contact with respiratory secretions during prolonged face-to-face interaction.
Prevention and Treatment
Preventive measures include:
- Avoiding close,personal,skin-to-skin contact with people who have mpox.
- Avoiding contact with materials that have been in contact with someone who has mpox.
- Practicing good hand hygiene.
- Vaccination: Vaccines are available and recommended for those at high risk of exposure.
Treatment for mpox is generally supportive, focusing on managing symptoms and preventing complications. Antiviral medications may be used in some cases [[2]].
Key Takeaways
- Mpox is a viral disease caused by the orthopoxvirus.
- The virus has two main clades, with Clade IIb driving the recent global outbreak.
- Mpox spreads through close contact and contaminated materials.
- Vaccination and supportive care are key strategies for prevention and management.
