viremia

(noun)

A medical condition where viruses enter the bloodstream and hence have access to the rest of the body.

Examples of viremia in the following topics:

  • Arboviral Encephalitis

    • Arthropod vectors transmit the virus upon biting, allowing the virus to enter the circulatory system and replicate and shed additional infection into the bloodstream (viremia).
    • Arboviruses usually stimulate the production of interferons and antibodies, which help to diminish the extent of viremia.

  • Immunodeficiency

    • The acute viremia, or spreading of the virus, is almost invariably associated with activation of CD8+ T cells (which kill HIV-infected cells) and, subsequently, with antibody production.

  • The Salk Vaccine Field Trial

    • The injected Salk vaccine confers IgG-mediated immunity in the bloodstream, which prevents polio infection from progressing to viremia and protects the motor neurons, thus eliminating the risk of bulbar polio and post-polio syndrome.
