    Insights

    Mumps vaccine viruses (MuV) were shed by children recently vaccinated with Leningrad-Zagreb or Leningrad-3 MuV. These cases confirm horizontal transmission of mumps vaccine viruses.

    Area of Science:

    • Virology
    • Epidemiology
    • Vaccinology

    Context:

    • Mumps vaccine virus (MuV) shedding and transmission are critical public health concerns.
    • Recent mumps outbreaks have raised questions about vaccine virus shedding.
    • Understanding the epidemiology of vaccine-derived MuV is essential for disease control.

    Purpose:

    • To investigate and report on mumps vaccine virus shedding.
    • To identify the epidemiological sources of transmitted mumps virus.
    • To confirm the etiology of horizontal transmission of mumps vaccine viruses.

    Summary:

    • This study reports on mumps vaccine virus shedding in laboratory-confirmed mumps virus (MuV) infections.
    • Children vaccinated with Leningrad-Zagreb or Leningrad-3 MuV were identified as the likely sources of transmitted MuV.
    • Polymerase chain reaction (PCR) with sequential restriction analysis confirmed the etiology of horizontal transmission for both mumps vaccine viruses.

    Impact:

    • Provides evidence of horizontal transmission of mumps vaccine viruses.
    • Informs public health strategies for mumps prevention and control.
    • Contributes to the understanding of vaccine virus shedding dynamics.

    Viral Meningitis

    Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

    Cytomegalovirus Disease01:27

    Cytomegalovirus Disease

    Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

    Viral Recombination00:57

    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.

    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...

    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...
