  • Understanding Viral Fever Causes


    Viral fever is highly infectious and communicable; it is most commonly spread in three ways: through direct contact with the offending virus, inhaling infected air and drinking or consuming contaminated water or food. Viral fever also spreads via sexual contact or the virus can be injected directly in to the blood by means of shared infected needles.

    The commonly seen viral fever causes are mentioned below:

    Consuming food or water that is contaminated with the virus
    Inhalation of the virus, inhalation of aerosolized particles
    Sharing infected articles, such as, clothes, napkins, handkerchiefs, fomites, etc.
    Sexual transmission
    Using shared, infected needles
    Direct inoculation in the blood

    Once the virus enters your body, through one of the above mentioned routes, it can take quite a few days (during which it multiplies) before the viral fever and the symptoms begin to become obvious. This period is called the incubation period. In fact, this is the reason for the rapid spread of viral infection.

    The infection then extends locally, to adjacent organs and then, in to the blood and / or lymphatic channels.

    The period of the primary infection varies from days to weeks. Expression of the viral infection clinically is a consequence of the virus proliferating at a specific site. Even though the fever comes down within a week, in some infections, the virus continues to reproduce, and causes constant infection and recurrent attacks.

    The doctor confirms the presence of the virus by doing a culture of the virus from pertinent samples / body fluids such as nasal swabs, skin rash, etc., or when the body demonstrates an increase in anti body levels in the blood sample.
