causes of rash on the body Anyway, we've all come acrosssuch manifestations on the skin as a rash. A rash is understood as a variety of skin rashes, not characteristic of a normal healthy skin condition. From a medical point of view, a rash on the body can be a manifestation of various skin diseases or internal disease, or be infectious or allergic. The medicine does not stand still: a huge database of information has been collected, where various forms of skin rashes are described with a variety of diseases. The rash itself is not a disease. This is just the manifestation of some other disease or the reaction of the body to the stimulus. Treatment of the rash, of course, depends on the causes of its occurrence. To begin with, let's figure out how they can still be. scabies on the body

Causes of a rash on the body

When determining the causes of the rash on the body, as a rule,the nature of rashes, their prevalence along the body, localization, the order of the rash, the time of the rash existence and its severity are revealed. Based on the analysis of these parameters, it is necessary to conduct a differentiated diagnosis taking into account all the factors preceding the precipitation, as well as the possible hereditary predisposition of the patient. First, you need to determine whether this rash is infectious or non-infectious in nature. Eruptions of an infectious nature

  • measles, chickenpox, rubella, scarlet fever (more common on the body in children, but in rare cases, are possible in adults);
  • infectious mononucleosis, sudden exanthema, abdominal or typhus fever, meningococcemia, infectious erythema, herpetic infection, shingles, etc.

Rashes of non-infectious nature:

  • an allergic rash;
  • with diseases of blood and vessels, connective tissue.

Diseases limited only to manifestations ofskin or primarily affecting it. About the case of the infectious nature of the rash on the body may indicate symptoms such as fever, general weakness and malaise, nausea or vomiting, headache, itching. Such a rash can itch. In addition, in this case, similar symptoms are also likely in relatives, relatives or colleagues who had direct contact with the sick person. Allergic manifestations of rashes on the body are not uncommon. If infectious signs have not yet been found, then it is worth considering the irritants (allergens) that can cause such an effect. Typically, the main sources of allergies can be pets (cats, dogs), certain medicines, food (for example, chocolate or citrus fruits), pollen allergens in plants, paint or solvents. In order to exclude allergies, it is mandatory to pass special tests to determine the predisposition to it. In addition, an allergic rash on the body may be accompanied by other symptoms of malaise (nasal congestion, Quincke's edema, sneezing, throat swelling, etc.). Eruptions associated with blood and vascular diseases occur for 2 reasons: disruption of normal functioning of platelets or their decrease in quantity. The appearance of a rash in this case has a pronounced type of hemorrhage (large or small), provoked, for example, by any trauma or fever in the usual cold. To diagnose the nature of the rash in medicine, the primary morphological elements of the rash, formed on previously unchanged healthy skin, are used. Secondary elements, respectively, are formed after the evolution of primary or after their complete disappearance. The size, shape, shape, color, the nature of the surface of the tumor, the presence of pruritus, etc. are taken into account in a diagnostic way. Such a subgroup of primary morphological elements includes such formations as abscesses, vesicles, blisters, spots, tubercles, nodules, etc. Sometimes, several different elements of the rash, although the disease will be only one. Thus, with chicken pox, it is possible to observe bubbles with liquid and combed crusts formed after the opened itchy vesicles. treatment of rashes on the body

A little about the diseases causing a rash

As mentioned above, the nature of the rashes canbe completely different. Consider several common diseases, one of the symptoms of which may be a rash. Chicken pox or chickenpox Chicken pox is considered a fairly common disease, usually found in childhood. The causative agent of the disease is the human herpes virus (type 3). Chickenpox is sick once in a lifetime, after which a person acquires lifelong immunity to this virus. In childhood, the disease is transferred fairly easily, mainly limited to a rash that itches. The chickenpox is airborne through the upper respiratory tract and the mucous membranes of the eyes (hence the name). The main age of the sick are children under 10-12 years old, attending kindergartens and other educational institutions. It is only one child to get sick, like all the other children, as if by chain reaction, pick up this dangerous virus. Basically, if such a case is detected, a quarantine regime is introduced in the group or class of the educational institution to exclude the further spread of chickenpox. The incubation period is 1-3 weeks. After that, almost simultaneously the body covers an itchy rash and the temperature rises sharply to 39-39.5 ° C. Sometimes it is accompanied by a headache and general weakness. The rash on the body is expressed in the appearance of pink small specks, which eventually become more prominent, gradually filling with liquid, forming bubbles. Extremely unpleasant is the fact that this rash on the body is very itchy. Therefore, you should exclude any scratching during itching, so as not to infect the wound. Moreover, when the rash on the body itches, the children, without realizing it, begin to comb the formed bubbles, thereby leaving themselves small scars. Usually, no specific treatment is required. But nevertheless, as a general recommendation appoint a bed rest (about a week). The usual lubrication of speckles with rash green is rather not a curative, but a preventive character from the penetration of a bacterial infection. In addition, it slightly reduces the characteristic itching. Adults can lubricate the rash with a weak solution of manganese, so that there is not too obvious and unaesthetic appearance. As an antipyretic, it is recommended in appropriate doses to take nurofen or ibuprofen. For most children, with proper care and compliance with all the recommendations of a doctor over the age of 1 year, chickenpox passes without any complications. Scabies caused by scabies Scabies refers to the category of skin diseases transmitted by contact. Infectious scabies mite (skin parasite) can be transmitted to a person with an elementary handshake or through objects, things belonging to a sick person. This disease is characterized by special itch moves (channels) on the body, where the female parasites lay their offspring. In these channels, scabies mites lay not only larvae and eggs for further reproduction, but also their living products, thereby inducing a state of hypersensitivity accompanied by pruritus and an allergic rash with signs of inflammation. Therefore, the rash on the body itches. The main symptoms of scabies are a specific rash and the accompanying itchy itching, which intensifies at night or after taking a shower with hot water. The rash with scabies looks like a set of meandering thin strips (3-15 mm in length) having a small vial at the end. This is the so-called itch moves. But sometimes there are eruptions in the form of papules or plaques. The favorite places for the rash are usually areas with thin skin (feet, palms, buttocks, genitals, interdigital spaces, face, etc.). Treatment must necessarily take place under the guidance and supervision of a dermatologist. Typically, it is recommended to use anti-stigma ointments containing lindane, sulfur, benzyl benzoate, etc. Bedding and things that the patient has to contact should be boiled thoroughly, weather for 5-7 days in the open air, and then iron. Herpes simplex (bladderwort) Herpes is considered to be a fairly common viral skin disease. To provoke the herpes virus can certain conditions contributing to this: ARI, infection, stress, exposure to direct sunlight. Rashes are a group of vesicles located on the mucous membranes and skin (face, mouth, genitals, etc.). The virus is transmitted by airborne droplets by direct contact with the diseased or virus carrier. A person with a herpes disease can experience pain, itching at the site of inflammation and rash. This skin disease is cured spontaneously. But to reduce the symptoms of the disease often apply oxolin ointment (2-3 times a day, lubricating the affected area) or cream with virolex (acyclovir). To minimize itching, wipe the inflamed areas with 1% menthol alcohol. These are just some possible causes of the rash on the body. In any case, it is worth to visit a doctor and follow his clear recommendations.
