    Study Notes

    Varicella-Zoster

    • Varicella-Zoster is caused by the human herpes virus 3.
    • Chickenpox and Shingles are two different manifestations of Varicella-Zoster.
    • Chickenpox is usually mild and self-managed.
    • Shingles occurs when the virus reactivates in adults.

    Hand Foot & Mouth Disease

    • Most often caused by group A coxsackie viruses.
    • Transmitted via air, coughing, faecal contact, and contaminated objects.
    • Common in nurseries.

    Herpangina

    • Caused by Coxsackie A virus.
    • Symptoms include malaise, sore throat, and vesicles in the mouth.
    • Transmitted via faecal-oral route or air droplets.

    Epstein-Barr Virus

    • The most common cause of Infectious Mononucleosis (Glandular Fever).
    • Remains latent in B-lymphocytes after primary infection.
    • Can cause Nasopharyngeal Carcinoma, Burkitt's Lymphoma, and Oral Hairy Leukoplasia.

    Mumps

    • Commonly occurs in childhood.
    • Causes parotitis.
    • Can cause complications such as swollen testicles, ovaries, temporary hearing loss, viral meningitis, and acute pancreatitis.

    Measles

    • Highly infectious disease spread through air droplets and surfaces.
    • Causes a characteristic exanthematous rash.
    • Complications include stillbirth, miscarriage, vision loss, subacute sclerosing panencephalitis (SSPE), fits and seizures, and encephalitis.

    Herpes Simplex Virus (HSV)

    • HSV1 and HSV2 cause lesions above and below the belt, respectively.
    • Primary infection can manifest as gingivostomatitis, herpetic whitlow, encephalitis, or genital herpes.
    • Secondary infection is triggered by stress, trauma, sunlight, menstruation, immunosuppression, and fatigue.

    Herpes Labialis (Cold Sore)

    • Common advice includes eating cool soft foods, avoiding triggers, using NSAIDs, cold compresses, sunblock, hydration, and rest.
    • To prevent spread, isolation, no kissing or oral sex is recommended.

    Herpes Simplex: General Management

    • Staff protection focuses on infection control, management of symptoms, and patient recognition.
    • Referral for further evaluation should be considered.
