The presence of a characteristic rash that accompanies a cold sore on his back, explains why the disease is synonymous with shingles
Shingles - from simple ailments and brain damage
or herpes. Affected skin chest, abdomen, back, so it seems rash, encircling the body. Often, the rash may be localized in the head and limbs. In terms of health impact, this form of manifestation of herpes infection is the most negative consequences for human health, significantly impact on his quality of life.
As the virus enters the human body
Is a viral disease, is highly contagious, that is, the virus is easily transmitted from an infected person during normal physical contact. In the period of active lesions on the skin of an infected person should be isolated from the surrounding loved ones, as they will be at risk of infection, closely associating with them in everyday life. Particularly noteworthy are newborns, the elderly, pregnant women, people with weakened immune systems. During the entire period of the disease, they do not have contact with the ill person.
The development of clinical disease caused by exposure to varicella-zoster virus. This is one of the varieties of the herpes virus. The first contact of the body with the virus occurs in childhood when the child develops chickenpox. For this reason, on the back of herpes occurs only in people who have not had chickenpox as a child. Twice during the life of a person can not become infected.
Causes of herpes on the back can be attributed to the direct effects of the virus. If we talk about the possible causes of acute illness, they are primarily concerned with the factors that lead to decreased immunity. After suffering colds, hypothermia, stress

often arise acute viral disease, as in this background developing immune deficiency.
Potential effects on human health
If the state of immune defense is not broken, then a viral disease does not significantly affect the health. After calming down of the clinical manifestations of the human body is a carrier of the virus for life. The second episode of the disease may occur only under the influence of predisposing factors. The virus causes severe changes in case of change of the body's defensive abilities.
The most severe changes were observed in the nervous system. Since the virus selectively affects the nerve ganglia, then he starts to actively proliferate in the nervous system with damage to its central departments.
Fabric brain or spinal cord, which is subjected to massive exposed to the virus is destroyed. The patient may experience severe paresis, paralysis. In extreme cases, death occurs.
Natural immunity against herpes virus is only for newborn children under the age of one month. Children receive a special protective antibodies from the mother, so at that age they are not at risk of infection. Herpes on the back of the baby can also cause serious complications, the child should be treated in accordance with the rules of the complex antiviral therapy, given the age. In most cases, tinea
Ringworm - not only infectious disease
Childhood should be seen as the existence of the disease, which significantly inhibits the body's immune system of children. It is necessary to exclude the presence of cancer, HIV, so the child should be comprehensively examined.
In some cases, treatment is indicated
Herpes treatment should be carried out on the back to people who have reduced immunity. If a person does not have a chronic disease, the body cope with an episode of viral disease on their own, recovery usually occurs within two to three weeks. Specific antiviral therapy is drugs that inhibit the activity of the virus in the body. Widely used the following drugs:
It has great significance frequency of administration of the antiviral drug, as this will depend on the effectiveness of therapy.
To prevent replication (or further multiplication) of the virus in the body, it is necessary to take acyclovir five times per day. For some patients it may create discomfort, and many prefer those drugs which require admission only a few times per day.
This requirement is fully consistent with modern antiviral drug Valtrex. After his admission to the body is a complete conversion of part of the drug valacyclovir to acyclovir
Acyclovir - as it is safe?
. The mechanism of therapeutic action is due to the influence of acyclovir directly on the virus (the virus causes death by blocking viral DNA chains). A convenient regimen Valtrex is enough double doses throughout the day.
It is not recommended to start treatment on their own shingles. How to treat a cold sore on his back, determined by the physician, given the individual characteristics of the human body. Multiplicity of reception and the dose received antiviral drugs depends on the functional state of the urinary system. If the patient has renal impairment, the dose is prescribed only once under the control of laboratory parameters. This feature should be considered if an episode of herpes on the back develops in patients with kidney disease.
Given that the virus selectively attacks the nervous system, herpes on the back often occurs with severe pain. During this period, you can take painkillers without exceeding the recommended therapeutic dose. Pain is often still remain for a long time after decrease in acute clinical manifestations, which affects the quality of life of the patient.
