    Insights

    Measles elimination in the U.S. is threatened by imported cases. Vaccination, especially for travelers, remains key to preventing measles outbreaks and protecting public health resources.

    Area of Science:

    • Public Health
    • Infectious Disease Epidemiology
    • Vaccinology

    Background:

    • The United States has eliminated endemic measles transmission.
    • However, measles importation from endemic regions continues to pose a public health threat.
    • This necessitates ongoing surveillance and prevention efforts.

    Observation:

    • Measles cases among U.S. residents during 2001-2004 were analyzed using surveillance data.
    • Cases originated from returning U.S. residents infected abroad, contact with infected travelers, or unknown sources.
    • An illustrative case report is included in the full analysis.

    Findings:

    • The majority of measles cases in U.S. residents are preventable.
    • Current vaccination recommendations, including for international travelers, are crucial.
    • Imported measles cases can lead to significant morbidity and public health expenditures.

    Implications:

    • Strengthening vaccination coverage is essential for maintaining measles elimination status.
    • Targeted vaccination strategies for travelers are critical to prevent re-establishment of endemic transmission.
    • Continued surveillance is necessary to rapidly detect and respond to imported measles cases.

    Smallpox01:24

    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.
    Respiratory Syncytial Virus Disease01:29

    Respiratory Syncytial Virus Disease

    Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
    Poliomyelitis01:17

    Poliomyelitis

    Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

    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 temporal or...
    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,...
