    Insights

    Travel-related monkeypox virus (MPXV) clade Ib cases were analyzed. The study highlights high secondary transmission risk among sexual and household contacts, informing targeted public health interventions.

    Area of Science:

    • Epidemiology
    • Infectious Diseases
    • Public Health

    Background:

    • Monkeypox virus (MPXV) poses a global health threat.
    • Clade Ib MPXV has been associated with recent outbreaks.
    • Understanding transmission dynamics is crucial for control.

    Purpose of the Study:

    • To analyze travel-related Clade Ib MPXV cases.
    • To identify risk factors for secondary transmission.
    • To inform targeted public health response strategies.

    Main Methods:

    • Retrospective analysis of 89 travel-related MPXV cases.
    • Data collected from 33 countries between August 2024 and July 2025.
    • Assessment of secondary transmission events and contact types.

    Main Results:

    • 89 travel-related Clade Ib MPXV cases identified across 33 countries.
    • Majority of cases identified in men.
    • Approximately one-third of cases resulted in secondary transmission.
    • Highest secondary transmission risk observed in sexual contacts, followed by household contacts.

    Conclusions:

    • Sexual and household contacts are key populations for MPXV transmission.
    • Public health interventions should prioritize these high-risk groups.
    • Targeted strategies are essential for controlling Clade Ib MPXV spread.

    Viral Recombination

    Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

    Infection01:20

    Infection

    When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
    The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

    Transmission-based Precautions I: Contact, Enteric, and Droplets

    Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
    Contact Precautions:
    Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

    Infectious Diseases and Their Occurrence

    Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable...

    Investigation of Disease Outbreaks

    Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...

    Arboviral Encephalitis

    Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
