Chickenpox, also known as varicella (/ ˌ v ɛ r ə ˈ s ɛ l ə / VER-ə-SEL-ə), is a highly contagious disease caused by varicella zoster virus (VZV), a member of the herpesvirus family. [ 3 ] [ 7 ] [ 5 ] The disease results in a characteristic skin rash that forms small, itchy blisters , which eventually scab over. [ 1 ]
Molluscum contagiosum (MC), sometimes called water warts, is a viral infection of the skin that results in small raised pink lesions with a dimple in the center. [1] They may become itchy or sore, and occur singularly or in groups. [1]
Varicella zoster virus is known to recur (after its initial presentation as chicken pox) as herpes zoster ("shingles"). Chicken pox appears nearly everywhere on the body, but herpes zoster tends to follow one or two dermatomes; for example, the eruptions may appear along the bra line, on either or both sides of the patient.

A chickenpox rash first appears on the chest, back, and face, and then spreads across the entire body. Getty Images People with chickenpox get an itchy, blister-like rash, caused by the varicella ...
Chickenpox-like rashes were recognized and described by ancient civilizations; the relationship between zoster and chickenpox was not realized until 1888. [29] In 1943, the similarity between virus particles isolated from the lesions of zoster and those from chickenpox was noted. [30] In 1974 the first chickenpox vaccine was introduced. [31]
It is sometimes also called the chickenpox skin test and the herpes skin test. It is a simple, low-cost, and rapid office based test. [1] Tzanck cells (acantholytic cells) are found in: Herpes simplex [2] Varicella and herpes zoster; Pemphigus vulgaris; Cytomegalovirus; Arnault Tzanck did the first cytological examinations in order to diagnose ...
The Molluscum contagiosum virus virion is described as oval-shaped and has the dimension of approximately 320 nm × 250 nm × 200 nm. The virus has two distinct infectious particles called the mature virion (MV) and the enveloped virion (EV), which differ in that the EV contains a second outer cellular membrane.
In this fashion, the virus can persist in the cell (and thus the host) indefinitely. While primary infection is often accompanied by a self-limited period of clinical illness, long-term latency is symptom-free. [citation needed] Chromatin dynamics regulate the transcription competency of entire herpes virus genomes.
