Shingles, or herpes zoster
Shingles - from simple ailments and brain damage
- A type of herpes infection. The disease is very contagious, but it can only catch the person who did not survive childhood chickenpox, as both of these diseases, and herpes zoster, and chickenpox are caused by the same type of herpes virus.
Causes of herpes zoster
Shingles (herpes zoster) is caused by herpes simplex virus type III, dubbed the varicella zoster virus. Herpes zoster virus causes chickenpox in children and
Chickenpox in children - a mild infection, but there are exceptions
. Most people suffer chickenpox in childhood, after which the virus "goes underground" - hides in the nerve ganglia. It is this virus is hiding and may further cause herpes zoster.
Is shingles contagious and is transmitted herpes zoster? Shingles - a highly contagious disease, it is instantly transmitted from person to person through contact with dirty hands, surrounding objects, and so on. But this happens only when in contact with the sick person is not moved earlier chickenpox. Therefore, a patient with herpes zoster should be isolated from people and especially by children, pregnant women, the elderly and immunocompromised patients (eg AIDS).
In most cases, shingles
Ringworm - not only infectious disease
It develops as a result of low immunity in people who have had chicken pox as a child. In this case the herpes zoster virus begins to multiply actively in the nerve ganglia, then "comes to the surface" - penetrates the skin epithelial cells, causing inflammation.
Such a reduction in immunity may occur with hypothermia, after an infection, surgery, injury, stress. Especially likely to develop shingles elderly, patients with diabetes, AIDS, cancer after chemotherapy and radiotherapy, the patients after organ transplantation and so on.
It was found that one in five, ten, endured in childhood chickenpox, it moves into the future (most often in the elderly), herpes zoster. But sometimes a disease very similar to herpes zoster, herpes simplex virus
Herpes simplex - in fact, not so simple
(HSV) types I and II, despite the fact that these types of herpes viruses are characterized by localization facial skin (HSV-I) and the genital mucosa (HSV-II). On the treatment of the disease is usually not recognized, as those and other pathogens are sensitive to the same antiviral.
Symptoms of herpes zoster
Shingles usually begins with increasing skin sensitivity in the course of the nerve. Then there are pains of different intensity in the course of the affected nerve. Sometimes the pains are minor, but they are often still very much concerned about the patient, especially at night, sometimes completely disrupt sleep.
After one to two days the skin in that area becomes red, swells, and on it appear close to each other arranged bubbles with clear content. The rash may cover large areas of skin for several days. Sometimes the rash covers the entire body - is a dangerous symptom that indicates a significant decrease in immunity, and the risk of complications. Simultaneously, the patient may increase the temperature, there are chills, malaise, headache and other symptoms of intoxication.
After a while, the bubbles burst from the first appearance of skin erosions and ulcers, and then gradually begin to dry and covered with yellowish or brown (if the contents of the bubbles mixed blood) crusts. After falling away crusts on the skin are sometimes pigmented brown or vice versa depigmented white spots. In most cases, these spots are in a few weeks or months, but sometimes remain for a lifetime. Severe skin lesions on it and scars may remain.
Shingles on the body can manifest itself only as pain along the nerves (for example, skin lesions over the intercostal nerves). In this case, the pain can be intense. Pain with herpes zoster may be completely absent even with significant skin eruptions.
Shingles can occur in the form of rashes on the skin in the ear, the external auditory canal and the skin around the ear. This localization process is not too rare, this increases the risk of spreading herpes infection on the cells of the brain and spinal cord. The disease may be accompanied by nausea, vomiting, headaches, dizziness, taste, hearing impairment, pain and tinnitus.
More rare localization process is the skin around the nose and the upper eyelid. It is also dangerous in terms of the spread of infection in the central nervous system as well as on the eyeball while the patient is in danger of violation of even blindness. Duration of disease - from two to four weeks, rarely - more.
Atypical localization of herpes zoster occurs very similar to herpes infection caused by HSV-I and HSV-II. To distinguish one from another type of infection is possible only with the help of laboratory tests.
