The most common and poorly controlled infections are herpetic infections. These are diseases of mammals, amphibians, fish and birds caused by Herpesviridae family viruses, which have a variety of clinical manifestations, usually chronic course, as well as different routes of transmission.
The main sign of infection is the rash of vesicles on the skin or mucous membranes, grouped in small ranges. Herpes manifests on the lips and skin around them, or on the external genitalia. At the place of spread, the disease can be oral or genital. Oral herpes is also called “lip colds. This is due to the fact that the disease is often manifested against the background of seasonal colds and seems to be their manifestation. However, this is not the case. Herpes is an independent disease, and colds are the reason for its development.
At present, the Herpesviridae family consists of about 100 viruses. At the same time, only 8 viruses of numerous Herpesviridae family cause human diseases.
The mechanism of distribution of this group of viruses consists in affection of organism cells, because of which, once in it, the virus remains there forever. Quite often, a person lives with the herpes virus throughout his life, which does not manifest itself in any way. This is a distinctive feature of the whole family of herpes viruses.
Reasons for herpes
As already mentioned, herpesvirus can stay in the body for a long time without any external manifestations. The disease may develop against the background of several reasons: hypothermia; colds; emotional exhaustion;
injuries; inadequate food, often on diets; and menstruation;
external diseases. All causes have a common feature – they lead to exhaustion. The virus starts to manifest itself when the body’s resistance decreases.
Herpes has one classic symptom – the appearance of vesicles on the skin and mucous membranes. They are distributed in small concentrated groups. In addition, the disease also has precursor signs. These include itching, burning sensation, light tingling around the mouth or genitalia. However, as a rule, almost no one pays attention to them, although at this stage, the treatment can give maximum effect.
The picture of simple herpes looks like this:
- In the oral or genital areas (depending on the type of herpes) there is an itch and a feeling of discomfort.
- The disease is manifested by the development of an inflammatory process. A small swelling is formed, rapidly growing.
- The swelling turns into blisters with transparent liquid content. They burst and the liquid in which there are millions of viral particles flows out. Then ulcers are formed in the blistering area.
- The ulcers dry out and then turn into scabs, which can be very painful and bleeding.
Why is herpes dangerous?
Herpes viruses are extremely common in nature and among people. This is largely due to its high infestation and easy transmission. At room temperature, the virus can remain active for up to 24 hours. Infection occurs by getting virus particles on mucous membranes (mouth, nose, eyes, genitals) from a sick person. In children it is enough to get on the undamaged skin. Having penetrated into the body, the virus migrates along the nerve endings to the nerve cells (neurons), where it lurks to favorable conditions. As soon as the immune protection is reduced, it begins to multiply and causes typical symptoms for herpes.
