Meaning of herpes

Herpes is an infection caused by a virus that manifests itself in the presence of skin vesicles. Locations of the manifestation of these vesicles are, in most cases, the face and the genital system, but the rash can also appear in the eye area or disseminated throughout the body.

It is an infectious disease, which often occurs together with febrile diseases, but is often not linked to any apparent reason.

Today, herpes therapy, and in particular the antivirus substances and the anti-herpetic vaccine, have greatly improved, and in some cases even complete healings are obtained. The viruses responsible for herpes belong to herpesvirus, a group of viruses with an icosahedral structure with double-stranded DNA and wrapped in a lipoprotein capsule. Herpes simplex, Zoster (or VZ) and Cytomegalovirus (which attack the salivary glands and kidneys, causing infectious mononucleosis) belong to this group.

Herpes simplex

Herpes simplex is a vesicular dermatitis due to a virus (Herpes homini, HSV) that lives in humans in a latent state. Vesicular lesions concern the epithelial cells of the mouth, lips or face mucosa; this herpes can also affect the genital system and in some cases cause meningitis and encephalitis. Herpes simplex is considered a sign of decreased organic defenses.

Shingles (shingles fire)

It is a variety of herpes that manifests itself acutely and is caused by the same chickenpox virus, which "awakens" even after many years. It nestles in the spinal nerve ganglia, giving rise to a particular manifestation, with localized pain and burning; within a day or two, vesicular lesions then appear in the area of ​​the intercostal nerves, the brachial plexus, the trigeminal nerve and the sciatic nerve.

The vesicles appear grouped on one side of the body and break a week after the appearance, leaving a brown spot. There is also a form that affects the eyes (ophthalmic herpes), rare and serious for the ocular complications that arise.

In general, the exacerbation of the virus in those affected by chickenpox is due to particular conditions (exposure to the sun, physical exertion and great tiredness, therapies with cortisone drugs and so on). The therapy involves taking antiviral drugs (aciclovir) which are also able to decrease the chances of a subsequent neuralgia.
