Viral Integumentary Infections Flashcards
This condition is severe if the patient is vitamin A deficient or malnourished
Measles
FA test on pharynx cells showing multinucleated giant cells is diagnostic of:
Measles
PH of the Measles
coryza, cough, conjunctiitis
Koplik spots
AB titers rise
Complications of congenital rubella syndrome
Risk to fetus in infected mother.
Cardiac, eye, hearing, CNS problems
German measles likely requires
close prolonged contact

German Measles: Rubella
Tx of Rubella
symptomatic; avoid infection during pregnancy and do NOT vaccinate pregnant women
Retrograde transport of virus into sensory neurons
Herpes simplex virus
Reservoir for HSV
humans only
Shallow vesicles on an erythematous base- balloons, crusts, PAINFUL!
HSV
DX HSV
direct tissue sample: ballooning pathology, Tzanck smear, FA assay for Ag’s, PCR, AB
Tx for Herpes
Acyclovir halts replication
Neonatal HSV
in utero, disseminates due to lack of immune response
The two unique properties of this condition are
- CNS replication
- Latent infection
Herpes
Pruritic lesions, fever, malaise, HA, neuralgia.
Lesions can be secondarily infected
Chicken Pox
If you have have facial lesions with the chicken pox…
LOW IMMUNE RESPONSE = bad
Organism that causes the chicken pox is

Most common childhood viral infection
Roseola infantum; 6th disease
2-5 day sustained fever followed by a rose-colored rash over the body
