Causes
Exanthema (also called sudden exanthema) is caused by human herpes viruses types 6 and 7 (HHV-6 and HHV-7) - the first is more dangerous and is the main causative agent. Once in the body, viral particles interact with immune complexes, provoking the formation of exanthema. Also, such viruses interact individually with the following biological structures:
- T lymphocytes;
- monocytes;
- macrophages (cells that devour foreign elements that enter the body);
- astrocytes;
- tree-like cells;
- epithelial cells, etc.
Exanthema in adults is observed much less frequently. It should be remembered that in adolescent children and adults, the HHV-6 virus is associated with a urinary infection, which is characterized by an asymptomatic course. Also, such a virus can, without manifesting itself, live in the tissues of the central nervous system, then become activated and cause:
- myelitis – inflammation of the soft tissues of the brain and spinal cord;
- meningoencephalitis is an inflammation of both soft tissues and meninges.
In addition, there is evidence that HHV-6 is capable of causing the development of lymphoproliferative pathologies - those that are manifested by the proliferation of lymphoid tissue. This means that when exanthema is detected, one should be wary of the described pathologies provoked by this type of virus.
Non-infectious causes of rash:
- allergies, for example, to medications (including such dangerous forms as urticaria and erythema multiforme);
- autoimmune diseases (rheumatic arthritis, systemic lupus erythematosus...);
- blood diseases;
- and many other reasons.
A rash, especially if it appears suddenly and is accompanied by other serious symptoms (fever, pain, itching, nausea and vomiting, deterioration in general health) requires immediate medical attention.
