A viral rash is one of the symptoms triggered by viral infections, but it depends on the type of virus. Some of the popular viral rashes include chickenpox and measles. Oftentimes, a typical viral rash is used by the doctor to determine the type of virus responsible.
Various viruses can trigger a viral rash in addition to other symptoms such as fever and cough. Most of these rashes are considered as “non-specific” which means that the rash is not specific or characteristic enough to pinpoint the virus responsible. The doctor could not determine the specific virus.
A viral rash can vary in size and shape. Nevertheless, they can appear as blotchy reddened spots. Many are likely to affect most of the body. Oftentimes, they manifest dramatically and can last for a few days. Sometimes, the rash is slightly itchy and can vanish without a trace in a few days.
Is a viral rash serious?
A viral rash on its own is not usually serious. Nevertheless, it is vital to ensure that the rash is not a symptom of a serious infection such as a meningococcal infection. Other indications that can suggest a meningococcal infection among infants and young children include unresponsiveness, unusual crying episodes, sleepiness and fever. The rash of a meningococcal infection is characteristically purple or reddened spots that do not fade if under pressure.
Among pregnant women, most infections that causes a viral rash will not cause any harm to the developing infant. Nevertheless, some can involve the infant such as the rubella virus. Pregnant women should avoid individuals who have the rash.
The abrupt presence of an extensive mottled rash is prevalent. It is frequently triggered by an infection that is viral in nature. The other accompanying symptoms might be troublesome. In case the other symptoms are mild, there is no issue for concern since it settles in a few days. There is specific treatment for the viral rash. The treatment is aimed on other symptoms.
Itchy rashes often respond to antihistamines that can be prescribed by the doctor. There are also a variety of creams available that can reduce the itchiness. A doctor should be consulted if worried about a viral rash or other serious symptoms.
