The shingles virus is transmitted by the airway, causing varicella, the eruptive virus of childhood, especially contagious. The reactivations of the latent virus occur later, in the form of the shingles, on the skin (skin), innervated by a lymph node in which the latent virus exists. Post shingles neuralgia persists 4-5 months after lesions disappear, with special treatment problems. Recently, a live attenuated antiviral vaccine has been introduced into pediatric practice.
The name indicates the two diseases that the virus can cause: varicella in the case of primary infection and the shingles area by reactivation.
The primary infection of varicella infection occurs after the virus enters the nasopharyngeal mucosa. At this level there is viral replication followed by the spread, lymphatic and blood. After the penetration and active replication of the virus in the blood, the invasion of the ectoderm (outer layer of the skin) occurs. This translates clinically by the appearance of characteristic lesions:
Blood spread in the case of varicella infection occurs in successive waves following the initial virus, which is why the eruptions have a polymorphic character (eruptive elements at different stages - from the macula to the crust) present simultaneously.
Complications in chickenpox:
The reactivation of the varicella infection occurs due to the fact that during the primary infection the virus migrates along the path of the nerve and then on the path of the infected ganglion, becoming latent (asleep) at this level. Under the influence of some immunosuppressive factors, reactivation followed by recrudescence occurs (re-intensification of the clinical symptoms of a disease during its decline). The result is a vesicular rash strictly localized (characteristically) to the skin area of the respective nerve. The eruption in case of chickenpox is preceded and accompanied by the painful hypersensitivity of the respective area. Also the varicella vesicles will go through the same evolutionary stages described in the primary infection.
