    Study Notes

    Herpes Simplex Viruses Overview

    • Herpesviridae family includes several viruses that infect humans, primarily HSV-1 and HSV-2.
    • Both viruses are large, enveloped, icosahedral with a double-stranded DNA genome.

    Oral Herpes (Cold Sores) - HSV-1

    • HSV-1 typically infects the oral mucosa leading to cold sores (oral herpes).
    • More than 67% of adults have been infected with HSV-1, often without memorable symptoms.
    • Transmission occurs mainly through casual contact during childhood, including kissing and sharing utensils.

    Genital Herpes - HSV-2

    • HSV-2 is mostly transmitted via sexual contact, causing genital herpes and painful lesions.
    • Lesions may resemble blisters or small cuts in tissue.

    Latency and Recurrent Infections

    • Herpes viruses can integrate their DNA into nerve cells, leading to latency.
    • The virus can reactivate, causing recurrent outbreaks, often triggered by stress, hormonal changes, illness, or UV exposure.
    • There are no cures; however, antiviral treatments can reduce the frequency and severity of outbreaks and lower transmission risk.

    Complications of HSV

    • HSV-1 and HSV-2 can result in serious complications if they infect critical areas, such as the eyes or in immunocompromised individuals.
    • Neonatal herpes infections are particularly dangerous if a baby is born to a mother with an active genital outbreak, potentially causing permanent damage or fatalities.
    • HSV can affect nerves and brain health, posing severe risks in immunocompromised patients.

    Herpetic Whitlow

    • Herpetic Whitlow occurs when HSV-1 or HSV-2 enters through cuts in fingers.
    • Dental hygienists and nurses are at high risk due to their occupational exposure to the virus, emphasizing the importance of protective gear, like gloves, during contact with patients.
