What May Cause a Rash

Body rash does not necessarily mean a disease. Sometimes it is a symptom of allergic reaction to changes in your diet or drugs.

Body rash may be a result of infectious disease, immunological system allergic reaction to allergens and insect bite. It may take a form of small spots, lumps, blisters or pimples – depending on the cause. It is sometimes accompanied by severe itching, yet it is not a rule.
Types of rash

In terms of their cause, we can identify the following types of rash:

• allergic,
• infectious,
• accompanying metabolic diseases.

In terms of their structure, we can distinguish between the following rashes:

• spotty
• lumpy,
• blistery,
• mixed.

In terms of area of occurrence, there are the following types:

• visible in single spots,
• generalized (cover large skin areas, e.g. torso, hands and legs).
• In terms of duration:
• fast subsiding,
• long-term.

Rash as a symptom of viral disease

Rash is very often a symptom suggesting viral diseases, such as measles, rubella, erythema (fifth disease or roseola) and chickenpox. See below to find descriptions of rash typical of each of these diseases.

As for measles, rash covers the entire body. At first it appears behind ears, then on the chin and finally covers the entire face. It is followed by neck, torso and limbs. At the beginning it takes a form of dark red spots which stand out of the skin surface a little. Then it may take a form of combined lumps. A distinctive feature of measles is dark brown colors on the skin which emerge when the rash subsides.
In the case of rubella, we also deal with generalized rash, yet spots are pale pink and usually smaller. Similar to measles, they combine to form larger units. They may emerge not only on the skin but also palate.

Fifth disease (erythema infectiosum) causes intensive rash of various looks. It emerges on surfaces of limbs, buttocks, torso and face. It does not cause discoloration, while spots and lumps do not peel. The roseola in turn is known for its generalized rash on the torso, yet spots are of medium-size and are pale pink.

The rash typical of chickenpox is generalized. It covers primarily the torso. With time spots turn into lumps and then into blisters containing cloudy liquid. After some time the blisters cave in and leave scabs behind. You can observe ulceration and blisters in the oral cavity.

Have you noticed any disturbing cutaneous eruptions? Remember that they not always signal infectious disease. A rash may accompany a change of eating habits, may also result from drugs intake. For more about this, read here: https://promreport.com/
