Few people know that chickenpox, which many young people are familiar with, is caused by a virus with the beautiful name Varicella Zoster. It can also cause herpes zoster, also called “herpes zoster” or “shingles.” Sometimes doctors prescribe this drug https://pillintrip.com/medicine/avirex in such cases.
The infection is sometimes caused by a reawakening of the latent varicella zoster virus. It is activated against the background of problems that contribute to decreased resistance: hypothermia, chronic diseases, malignant diseases, disturbed metabolism, HIV infection. Therefore, a thorough examination is important to find the cause of the problem.
This disease causes fever, fever and flush. The sensations resemble those of a general infection. Skin problems (vesicular rash) with noticeable pain syndrome occur. Varicella acts as a dermatoneurotropic virus. It affects the mucous membranes and skin, with areas of the spinal cord and brain affected in particularly severe cases.
Shingles is more common in the fall and winter. People who have already had chickenpox are particularly susceptible. About 15 people per hundred thousand are affected. In rare cases, the disease can recur. A child can contract chickenpox if exposed to the disease.
Pathohistology is similar to that of common herpes. Inflammatory infiltrates develop in ganglion cells and nerve fibers. Microscopic hemorrhages occur, the nerve fibers dystrophy, and the cerebrospinal fluid contains increased amounts of proteins.
It is important to note that the incubation period after infection can last two to three years.
Stages of the disease
The development of the disease is usually accompanied by fever, lethargy and intercostal neuralgia. Headaches are common. Spots, vesicles with a serous substance and pustules are formed on the skin. Then erosions and crusts are formed. Edematous patches may appear. They close together and form painful lesions. The pain may be sharp, dull or pulling. Sometimes it is confined to the external lesions, sometimes it is vagal. An unpleasant feature of the disease is the persistence of the pain (postherpetic neuralgia), which sometimes persists for years despite therapy, even after the external lesions have resolved.
Clinical variants of herpes zoster:
Diagnosis of the disease is usually not a problem for an experienced specialist – there is a typical localization of herpetiform elements along the innervation, at a swollen base and pronounced pain sensations.
