    Study Notes

    Varicella-Zoster

    • Caused by the human herpes virus 3, also known as varicella zoster virus.
    • The virus remains dormant in the body after initial infection.
    • This virus is commonly referred to as chickenpox or shingles.
    • Chickenpox is typically a mild and self-managed illness affecting children.
    • Shingles or herpes zoster occurs with reactivation of the virus.
    • Shingles commonly affects adults and is usually more serious.
    • Chickenpox has a 2-week incubation period.
    • Symptoms of chickenpox include fever, rash, papules that become vesicular and itchy but painless.
    • Chickenpox rash is different from the rash in shingles.

    Shingles

    • It is a reactivation of the same virus that causes chickenpox.
    • Commonly affects adults.
    • The virus is reactivated in the dorsal root ganglia and the trigeminal nerve.
    • Symptoms include a painful, vesicular rash, fever, fatigue, chills, and headache.
    • Shingles can affect the facial nerve, leading to a condition called Ramsay Hunt Syndrome.
    • Ramsay Hunt Syndrome is characterized by vesicular rashes on the tympanic membrane and auditory canal, as well as unilateral facial palsy.

    Hand Foot & Mouth Disease

    • Caused by group A coxsackie viruses.
    • Common symptoms include malaise, fever, and sores in the mouth.
    • Spots may also appear on the buttocks and groin.
    • It is highly contagious and transmits via air droplets, coughing, fecal contact, and contaminated objects.
    • Outbreaks are common in nurseries.

    Herpangina

    • Caused by the Coxsackie A virus.
    • Main feature is the presence of vesicles in the mouth.
    • Symptoms include malaise, sore throat, fever.
    • Commonly occurs in summer and is frequently self-managed.
    • It is transmitted via fecal-oral route or air droplets.

    Epstein-Barr Virus (EBV)

    • Also known as Human Herpesvirus 4 (HHV-4).
    • Most people contract EBV in early childhood without symptoms.
    • When teenagers or young adults are infected, it may cause infectious mononucleosis (glandular fever).
    • EBV becomes latent in B-lymphocytes, meaning it remains in the body for life.
    • Humans are the only known host for EBV.

    EBV associated conditions

    • Glandular fever (Infectious Mononucleosis).
    • Burkitt’s Lymphoma, a type of cancer affecting the lymphatic system, primarily in children and adolescents.
    • Nasopharyngeal carcinoma, a type of cancer developing in the nasopharynx.
    • Oral hairy leukoplakia, a condition affecting the mucous membranes of the mouth.

    Mumps

    • Typically affects children.
    • Caused by the Paramyxovirus.
    • Characterized by painful swelling of the parotid glands (parotitis).
    • Complications after puberty can occur in both males and females.
    • 1 in 4 males may experience pain and swelling of the testicles.
    • 1 in 20 females may experience swelling of the ovaries.
    • 1 in 20 can experience temporary hearing loss.
    • 1 in 1000 may develop viral meningitis.
    • 1 in 20 may develop acute pancreatitis.

    Measles

    • Caused by measles morbillivirus.
    • Highly contagious, spreading via air droplets and surfaces.
    • Enters the body through the respiratory tract.
    • Symptoms include fever, headache, sore throat, and a characteristic exanthematous rash.
    • Koplik’s spots may also be present.
    • Measles complications include:
      • stillbirth and miscarriage.
      • vision loss.
      • fatal brain complication called subacute sclerosing panencephalitis (occurs 1 in 25,000).
      • seizures.
      • encephalitis .

    Herpes Simplex Virus (HSV)

    • There are two types of HSV: HSV 1 and HSV 2.
    • HSV 1 typically causes orofacial lesions “above the belt”.
    • HSV 2 typically causes genital lesions “below the belt”.

    Primary HSV Infection

    • Genital Herpes: An initial infection with HSV 2 that can cause painful sores on the genitals and buttocks.
    • Herpetic Whitlow: Infection of the fingers, typically caused by HSV 1, that can cause painful blisters.
    • Encephalitis: Inflammation of the brain caused by HSV, which can be life-threatening.
    • Primary Gingivostomatitis: An initial infection with HSV 1 that can cause painful sores in the mouth and on the lips.
    • Herpes Labialis (Cold sore): Recurrent HSV 1 infection, commonly seen on the lips but can occur in the mouth.

    Secondary HSV Infections

    • Triggered by factors like:
      • stress.
      • trauma.
      • sunlight.
      • menstruation.
      • immunosuppression.
      • fatigue.

    General Management of HSV

    • Recognition: Early identification of symptoms is important.
    • Staff protection: Safeguarding personnel and patients from the virus is crucial, especially in healthcare settings.
    • Infection control: Implementing measures to prevent the spread of the virus.
    • Management of symptoms: Providing treatment to alleviate the symptoms and discomfort.
    • Referral: Consultation with a healthcare professional for appropriate medical care and follow-up.
