    WHO Declares M-Pox a Public Health Emergency Again as Global Cases Surge | mPox Virus

    World Health Organization (WHO) has reaffirmed its classification of mPox virus as a Public Health Emergency of International Concern (PHEIC) due to a recent surge in cases worldwide. This decision comes as virus continues to spread geographically, affecting regions far beyond its original epicenter in Democratic Republic of Congo (DRC). mPox virus, primarily associated with close-contact transmission, has now become a global concern, prompting need for urgent action.


    Understanding mPox Virus

    mPox virus, formerly known as monkeypox, is a zoonotic viral disease that spreads through close physical contact, respiratory droplets, and contaminated objects. Its symptoms include:

    • Flu-like symptoms: Fever, fatigue, muscle aches, and headaches.
    • Lesions and rashes: Characteristic pustular skin lesions that can spread across body.
    • Lymphadenopathy: Swollen lymph nodes are a distinguishing feature.

    While disease is generally self-limiting, certain strains and inadequate healthcare infrastructure in affected regions can lead to severe complications or fatalities.


    Geographic Spread and Global Impact

    Resurgence of Clade Ib Variant

    current global surge is largely attributed to Clade Ib variant of mPox virus. Initially concentrated in DRC, this strain has now spread to:

    • Neighboring African countries
    • Europe (including United Kingdom, Germany, and Sweden)
    • Asia, with cases reported in India and other nations

    This unprecedented geographic spread highlights global nature of outbreak and need for a coordinated international response.

    Key Statistics

    • Suspected cases in Africa (2024): Over 46,000
    • Suspected deaths in Africa: More than 1,000, with majority in Congo
    • Confirmed cases worldwide: Rising rapidly across multiple continents

    WHO’s Declaration and Emergency Measures

    mPox virus was first classified as a PHEIC in August 2024. WHO’s Emergency Committee recently reaffirmed this high-alert status after evaluating escalating situation. organization cited three primary concerns:

    1. Rising Case Numbers: Increasing infections across diverse regions.
    2. Geographic Spread: Expansion into countries with limited or no previous cases.
    3. Need for a Cohesive Response: necessity for unified global efforts to curb transmission.

    Vaccination Efforts to Combat mPox Virus

    Vaccination remains a critical component of response to mPox virus. WHO has expanded list of approved vaccines to counter virus effectively.

    Approved Vaccines

    1. Bavarian Nordic’s M-Pox Vaccine: Approved earlier in 2024, this vaccine has been distributed to high-risk regions.
    2. KM Biologics Vaccine: Added to WHO’s emergency-use list in September 2024, this vaccine is expected to bolster immunization efforts.

    Both vaccines target high-risk populations, including healthcare workers, close contacts of infected individuals, and vulnerable communities in outbreak regions.


    Challenges in Controlling mPox Virus

    resurgence of mPox virus has exposed several challenges that complicate containment efforts:

    1. Healthcare Infrastructure

    • Inadequate healthcare systems in many affected regions, particularly in Africa, have hindered timely diagnosis and treatment.
    • Lack of access to vaccines and antiviral treatments exacerbates crisis.

    2. Public Awareness

    • Misinformation and stigma surrounding mPox virus have delayed reporting and treatment in certain areas.
    • Awareness campaigns are needed to educate public on prevention and symptoms.

    3. Rapid Geographic Spread

    • spread to countries with no prior exposure to virus has strained healthcare systems and surveillance networks.

    Global Response to mPox Virus

    WHO has urged countries to strengthen their healthcare infrastructure, enhance surveillance, and prioritize vaccination campaigns. Several nations have already implemented measures to curb virus’s spread.

    Table: Key Responses to mPox Virus by Region

    RegionKey MeasuresChallenges
    AfricaExpanded vaccination campaigns, public awareness drivesLimited healthcare resources, high mortality
    EuropeEnhanced border screening, rapid response teamsRising cases despite robust healthcare systems
    Asia (India)Vaccination distribution, public education initiativesUnderreporting and lack of vaccine access
    GlobalWHO-led unified response, emergency vaccine approvalCoordination and funding gaps

    Preventive Measures Against mPox Virus

    Individuals can reduce risk of infection by following these preventive steps:

    1. Avoid Close Contact: Minimize physical contact with infected individuals or animals.
    2. Practice Hygiene: Regularly wash hands and sanitize frequently touched surfaces.
    3. Wear Protective Gear: Use masks and gloves when caring for infected persons.
    4. Vaccination: Get vaccinated if eligible, particularly in high-risk areas.

    Future Implications and Ongoing Research

    1. Strengthening Surveillance

    Improved global surveillance systems are critical for early detection and containment of mPox virus.

    2. Research on New Treatments

    Ongoing research focuses on developing antiviral therapies and enhancing vaccine efficacy to provide long-term protection.

    3. Addressing Stigma

    Efforts to reduce stigma associated with mPox virus are essential to encourage early reporting and treatment.


    Conclusion

    reaffirmation of mPox virus as a Public Health Emergency of International Concern underscores urgency of addressing this global health crisis. With over 46,000 suspected cases and rising fatalities, a coordinated global response is vital to contain virus’s spread and mitigate its impact.

    WHO’s emphasis on vaccination, public awareness, and international cooperation offers a roadmap for combating mPox virus. However, sustained efforts, adequate funding, and robust healthcare systems are needed to bring this outbreak under control.

    As world grapples with this resurgent threat, lessons learned from mPox virus outbreak could serve as a foundation for addressing future public health emergencies.
