Study Notes

Herpes Simplex Virus (HSV)

HSV-1 typically causes oral lesions (above the belt)
HSV-2 typically causes genital lesions (below the belt)
Primary infection can manifest as gingivostomatitis (HSV1), genital herpes, herpetic whitlow, or encephalitis (HSV2)

Varicella-Zoster (Human Herpes Virus 3)

Causes chickenpox and shingles
Chickenpox is the primary infection
Shingles is the reactivation of the dormant disease
Chickenpox is common in children and usually mild
Chickenpox is more serious if contracted as an adult
Chickenpox has a two-week incubation period

Varicella-Zoster Symptoms

Chickenpox symptoms include fever and rash
Chickenpox rash starts as papules, becomes vesicular and itchy but painless
Shingles rash is painful
Chickenpox is not contagious once scabs have formed

Shingles

Shingles is a reactivation of the varicella-zoster virus dormant in the dorsal root ganglia and trigeminal nerve
Shingles can be triggered by trauma or drugs
Shingles occurs on one (unilateral) side of the body

Ramsay Hunt Syndrome

Ramsay Hunt Syndrome (shingles of the facial nerve), is rare
Ramsay Hunt Syndrome symptoms include vesicular rash in the auditory canal, unilateral facial palsy, vertigo, and taste changes

Hand Foot & Mouth Disease

Hand-foot-and-mouth disease is mainly caused by group A coxsackieviruses
Hand-foot-and-mouth disease is highly contagious
Hand-foot-and-mouth disease spreads through the air, coughing, fecal contact, and contaminated objects
Hand-foot-and-mouth disease is common in nurseries and young children
Hand-foot-and-mouth disease symptoms include malaise, lethargy, and spots on the buttocks and groin

Herpangina

Herpangina is caused by the same virus as hand-foot-and-mouth disease
Herpangina symptoms include vesicles in the mouth
Herpangina commonly affects children aged 3 to 10 years

Epstein-Barr Virus (Human Herpesvirus 4)

The Epstein-Barr Virus (EBV), commonly known as the 'kissing disease', is present in most individuals
EBV is typically contracted in childhood
EBV remains latent in the body until reactivated
EBV is transferred through saliva, usually via kissing
