Q

Varicella (VZV, HHV-3)
etiology
rash description
spread

A

Varicella
- “chicken-pox”

Rash
- puritic, centrifungal
- papules which become vesicles, pustualar, pop and then crust over
- “dew drop on rose petal” : red base with vesicle on top
- on the trunk, back, face, scalp etc.

Infection Spread
- through direct or droplet contact
- 2-3 incubation period

Viral Progression
- 2-3 weeks incubation afte rexpsoure
- low grade fever, malaise
- rash appears: contageous period!!
- rash: papule, vesicle, pustule, crusts & ITCHYYYYY
- rash crusts: no longer contageous

Q

Varicella
diagnosis
treatment

A

Diagnosis
- PCR of the vescicular fluid

Treatment
- reminder: the virus lays dorment in the spinal nerve root ganglion (dorsal root and crainla nerves) and reppears as shingles later
- treatment within 24 hours of rash
- Acyclovir for those under 2
- Valacyclovir
- monitor renals!

*technially dont have to treat if theyre healthy, but we do treat those under 2, those immunocomp.

Nonpharm
- isolate pt. until crusts
- calamine for itching
- NO asprin
- self litiming in healthy pt

diagnosis
treatment

Treatment
- symptomatic

Symptomatic
- antipyretics (tylenol/motrin)
- fluids
- treat any bacterial superinfections

treatment
