Mpox 2025: Rising Global Threat, Rapid Spread
Introduction
In 2025, Mpox (Monkeypox) has emerged as a significant global health concern, with a dramatic increase in cases and new outbreaks in regions previously unaffected by the virus. More than 137,000 confirmed Mpox cases have been reported worldwide since 2022, spanning over 130 countries and resulting in hundreds of deaths. Driven by highly contagious viral strains and shifts in transmission patterns, Mpox's expansion highlights urgent challenges for public health agencies, demanding robust response strategies to curb its rapid international spread
What Is Mpox?
Mpox, formerly known as monkeypox, is a contagious viral disease caused by the Mpox virus—a member of the orthopoxvirus family, related to smallpox. It is characterized by flu-like symptoms such as fever, headache, muscle aches, swollen lymph nodes, and a distinctive skin rash that can develop anywhere on the body, most commonly on the face, hands, feet, and genital areas. The rash typically goes through several stages—starting as flat sores, turning into fluid-filled blisters, pustules, and then scabbing over before healing. Mpox spreads through close contact with infected individuals, contaminated objects, or infected animals, and symptoms generally last 2–4 weeks.
How Mpox Spreads
Direct contact: Touching skin lesions or body fluids of an infected person
Respiratory droplets: Prolonged face-to-face exposure, especially in households
Contaminated objects: Bedsheets, towels, and clothing can carry infectious material
Sexual networks: Recent global outbreaks have been linked to intimate contact, most notably among men who have sex with men (MSM)
Animal-to-human: Rare, but possible via handling wild animals, especially in Africa
Expansion to New Regions
The World Health Organization (WHO) highlights notable increases in cases in South-East Asia and the Western Pacific, while Africa, Europe, and the Americas still report the highest numbers. Urban and rural expansion, new viral clades, and evolving modes of transmission have contributed to the spread.
Prevention Strategies
Effective prevention is crucial to halting the spread of Mpox:
Vaccination: The JYNNEOS (MVA) vaccine is FDA-approved and recommended for high-risk individuals. Efficacy improves with full two-dose coverage.
Hygiene: Wash hands frequently and disinfect shared surfaces and linens.
Isolation: Infected individuals must isolate until all lesions are fully resolved.
Avoid close contact: Refrain from touching people with visible rashes or engaging in intimate contact with multiple/unknown partners during outbreaks
Use PPE: Healthcare workers should follow infection prevention protocols with gloves, gowns, masks, and eye protection.
Application Process for Vaccination
Eligibility:
Adults and children (with emergency FDA approval for children under 18)
People at elevated risk (MSM, healthcare workers, laboratory staff, close contacts of cases)
Immunocompromised individuals or those with chronic health conditions
Steps:
Contact your local health department or healthcare provider
Schedule the two-dose JYNNEOS vaccine, administered four weeks apart
Report any history of mpox-like symptoms to determine vaccination need
Important Documents Required
Valid government-issued ID
Insurance information (if applicable)
Proof of potential exposure (contact tracing, workplace records)
Medical history, including immunization records and chronic health conditions
Who Should Be Vaccinated?
Describe recommended treatments and care for Mpox patients
Supportive Care
Pain and Fever Relief: Use over-the-counter analgesics such as acetaminophen or NSAIDs for pain and fever relief.
Skin and Rash Care: Clean lesions with sterile water or antiseptic, keep skin dry and uncovered when alone, and cover lesions with clothing or bandages in shared spaces. Avoid scratching and keep hands clean before and after touching lesions.
Hydration and Nutrition: Maintain proper hydration, eat well, and get sufficient sleep to support recovery.
Isolation: Patients should isolate until all lesions have healed completely—crusted, separated, and healthy skin formed underneath.
Mental Health: Stay mentally active and connected with loved ones via technology during isolation.
Antiviral Treatments for Severe Cases
Tecovirimat (TPOXX): The primary antiviral considered for severe Mpox, available under the Strategic National Stockpile.
Other Antivirals: Brincidofovir, cidofovir, and Vaccinia Immune Globulin (VIGIV) may be used in combination or as alternatives for some cases, especially if tecovirimat is contraindicated or resistance is suspected.
Supportive Therapies: Sitz baths for proctitis, saltwater mouth rinses, and topical treatments may alleviate pain from lesions.
Infection Control
Healthcare Settings: Maintain monitoring and isolation precautions for at least 21 days post-exposure or until symptoms resolve.
Mpox usually resolves in 2–4 weeks, but close monitoring and supportive care are essential, especially for immunocompromised or severely ill patients.
Identify criteria for hospitalization or advanced treatment in Mpox
Hospitalization or advanced treatment for Mpox is recommended for patients with severe symptoms, complications, or underlying health conditions, especially immunosuppression, advanced HIV, or involvement of critical organ systems.
Criteria for Hospitalization
Severe or Widespread Lesions: Large numbers of skin lesions, confluent or necrotic lesions, lesions involving the mouth, eyes, or genitals, or severe lymphadenopathy.
Complications: Presence of secondary bacterial infections, sepsis, encephalitis, myocarditis, pneumonia, or ocular involvement requiring close monitoring.
Respiratory or Neurological Symptoms: Difficulty breathing, swallowing, neurologic changes, or severe pain—especially proctitis or pharyngitis unresponsive to outpatient support.
Immunocompromised Status: Advanced HIV (CD4 count <200 cells/μL), transplant recipients, very young children, pregnant women, and persons with other serious immune deficiencies are at much higher risk and may require advanced care.
Failure of Outpatient Care: Progressive infection despite proper supportive or antiviral therapy and situations where safe isolation at home is not possible.
Indications for Advanced Treatment
Consider antivirals (Tecovirimat, Brincidofovir, Cidofovir, VIGIV) for severe cases or patients at risk of life-threatening disease.
Supportive therapies for severe pain, dehydration, and organ involvement may include IV fluids, pain management, antibiotics for secondary infections, and specialized care (e.g., ophthalmology for eye involvement).
Patients exhibiting these criteria should be closely monitored, and care should be individualized based on severity and risk profile.
Conclusion
In conclusion, most Mpox patients recover fully with supportive care, which includes symptom management—such as pain and fever relief—attention to skin care, hydration, and nutrition. Hospitalization and advanced therapies are reserved for severe cases, high-risk groups, or those facing complications such as extensive lesions, secondary infections, or immunocompromise. While no FDA-approved antiviral exists for Mpox, agents like tecovirimat may be considered in critical scenarios, guided by clinical discretion. Effective prevention, early intervention, and proper isolation remain essential to control the spread and improve outcomes for all affected individuals.
