Reasons of rash

Various changes suddenly appearing on the skin doctors call a rash. There are some tens illnesses where the rash always happens. The overwhelming majority of these diseases are not so terrible but they can be caught very often and the rush that accompanies these diseases can turn out to be dangerous so it is necessary always it is necessary to be cautious.

To begin with Jacob Bogatin states that there are three groups of illnesses when a rush can appear on the skin:
• Infectious diseases.
• Allergic diseases.
• Illnesses of blood and vessels.
Let's consider them in detail.

Infectious diseases — the most frequent reason of a rash and it is easily to be convinced that the reason of a rash an infection. After all, besides a rash, it is necessarily to find out other signs of infectious disease that can be the following: contact to the infectious patient, the sharp beginning, body rise in temperature, appetite loss, a fever, something is ill (a throat, a head, a stomach), or something is itching, either a cold, or cough, or a diarrhoeia.

J.Bogatin says that there is a rash at the following illnesses which cause viruses: measles, German measles, chicken pox are the most frequent, but there is a set of others with terrible names — herpetic infection, infectious mononucleosis, infectious reddening, sudden exanthema and etc. The feature of all these illnesses is practically a full absence of possibilities essentially to help the patient as effective ways of struggle against viruses for the present have not thought up. But anything especially sad in it is not present: the human body within one-two weeks with a virus consults as well.

Bacteria can be the reason of infectious rashes. With them, on the one hand, is easier — there are antibacterial preparations (antibiotics, sulfanilamides), capable ill to help. But, on the other hand, diseases in itself can be serious enough when the rash is so, a trifle, in comparison with all the rest.

The most frequent bacterial infection with a rash — a scarlet fever, but at all on hearing set of other illnesses at which there is a rash, — belly and rash typhus, the syphilis, the meningitis, the staphylococcal infection (the list, unfortunately, it is far not full).

Rash as an allergy exposure — all in all it is a rarity (to put it mildly). Thoughts concerning the allergic nature of illness in general and rashes in particular arise, as a rule, when, first, there are no infection signs — i.e. the general condition, normal temperature is not broken especially, appetite and secondly was not gone, is on what to sin — i.e. Contact to something (someone) who could be an allergy source took place.

From the above listed signs Jacob Bogatin can easily draw a conclusion on presence of four basic variants of an allergy — food, medicinal, respiratory (respiratory) and contact. The possible reason is not always seen clearly and the search for a diagnosis often transforms the doctor, the patient and his/her relatives into Sherlok Holmes's true followers.
