Reactivation of chickenpox contracted in infancy.

چکیده
Varicella zoster virus DNA in mononuclear cells was studied by the polymerase chain reaction to obtain virological evidence of reactivation in the children who had contracted chickenpox in infancy. The results appear to explain why chickenpox in infancy is a risk factor for herpes zoster in immunocompetent children.

Varicella is a common and worldwide disease in childhood. It causes primary (chickenpox) and latent infection that may lead to a reactivation disease called zoster (shingles). Zoster or shingles is caused by reactivation of the virus that has been latent in the spinal dorsal ganglion and may occur even in immunocompetent hosts. Although zoster is rare in children, it ma...
متن کاملIntegrating between-host transmission and within-host immunity to analyze the impact of varicella vaccination on zoster
Varicella-zoster virus (VZV) causes chickenpox and reactivation of latent VZV causes herpes zoster (HZ). VZV reactivation is subject to the opposing mechanisms of declining and boosted VZV-specific cellular mediated immunity (CMI). A reduction in exogenous re-exposure 'opportunities' through universal chickenpox vaccination could therefore lead to an increase in HZ incidence. We present the fir...

Herpes zoster as a reactivated phase of chickenpox is very rare in infancy due to the protective effect of the maternal immunity against the virus.1,2 Overall rate of zoster is 3.40 cases per 1000 persons. The lowest incidence is less than 10 years old (0.74/1000) per year. The earliest age reported is in a 3-month old infant.3 Herein we present a 3 month-old otherwise healthy boy with herpes z...

The varicella zoster virus primarily causes chickenpox. Herpes zoster is a typical late manifestation with reactivation of latent virus in sensory ganglia. Chickenpox is a highly contagious disease. Herpes zoster has been assumed to be less contagious, but studies have shown that reactivation of the varicella zoster virus also leads to significant spread of the virus (1–4). There has been incre...
متن کاملHerpes zoster in a 4-month-old infant.
Herpes zoster is caused by reactivation of varicella zoster virus (VZV) from the dorsal sensory ganglia or the cranial nerve ganglia after a previous primary infection with chickenpox. It is known that pediatric zoster rarely occurs and usually not so severe when it develops, except in immunocompromised children 1) . In particular, herpes zoster in infancy is very rare but can be developed foll...
