Exposure to mumps during air travel--United States, April 2006

    Insights

    Iowa is facing a significant mumps outbreak that began in December 2005, with 515 cases reported by April 2006. The outbreak has spread to six neighboring states, prompting further investigation.

    Area of Science:

    • Epidemiology
    • Public Health

    Background:

    • A large mumps outbreak began in Iowa in December 2005.
    • By April 10, 2006, 515 possible mumps cases were reported in Iowa.

    Purpose of the Study:

    • To report on the extent and spread of a mumps outbreak in Iowa.
    • To highlight potential links to cases in neighboring states.

    Main Methods:

    • Surveillance data from the Iowa Department of Public Health (IDPH).
    • Analysis of case counts and geographical spread.
    • Monitoring of potential linked cases in neighboring states.

    Main Results:

    • 515 possible mumps cases reported in Iowa in 2006.
    • Mumps activity under investigation in Illinois, Kansas, Minnesota, Missouri, Nebraska, and Wisconsin.
    • The outbreak has spread across Iowa.

    Conclusions:

    • Iowa is experiencing a substantial mumps outbreak.
    • The outbreak shows potential for regional spread to neighboring states.
    • Further investigation is needed to understand the outbreak's causes.

    Chickenpox01:20

    Chickenpox

    Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...

    Transmission-based Precautions II: Airborne and Protective Environment

    Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
    Airborne precautions:
    Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

    Pulmonary Tuberculosis I

    Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
    Causative Organism
    The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

    Smallpox

    Smallpox is a severe contagious disease caused by the Variola major virus, a double-stranded DNA member of the Poxviridae family.Variola major transmission occurs primarily via inhalation of virus-laden droplets or direct contact with infectious scabs. The incubation period averages approximately seven days, although it may range from 7 to 17 days depending on the inoculum and host factors.Clinically, the prodromal phase is marked by an abrupt onset of high fever, malaise, headache, and myalgia.

    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...
