The causative agent of varicella is the DNA-containing virus Varicella-Zoster from the family Herpesviridae (refers to herpes viruses).
The source of infection is a sick person (it becomes contagious one day before the appearance of the first rash and within 5 days after the appearance of the last elements of the rash). It should be noted that the source of infection may be patients with shingles. The virus is contained in the vesicles, at the stage of crusts, it is no longer detected.
Infection occurs by aerogenic and airborne droplets, from here and the name of chickenpox (the disease is carried by the wind). This disease is very contagious, so most of the population suffer from chickenpox in childhood. Chickenpox in newborns and children under 6 months is extremely rare, as this group of children has a transplacental (through the placenta) and lactogenic (through milk) passive immunity from the mother. The easiest chickenpox occurs in children from 2 to 12 years. Newborns, infants and adults (if they become ill) – suffer from chickenpox much harder.
