Associated symptoms

Since a skin rash after fever is often the basis of an infectious disease, there are often characteristic accompanying symptoms that are typical for the individual diseases. In the case of infectious diseases, there are generalized symptoms such as cough, sore throat and swelling of the cervical lymph nodes in addition to fever. The three-day fever can be accompanied by water retention in the eyelids (edema) and diarrhea.

Measles can be accompanied by a general feeling of illness as well as conjunctivitis or photophobia. Rubella often leads to a characteristic rash, which is preceded by fever. The Epstein-Barr virus is characterized by inflammation of the tonsils.

The enlarged tonsils often show a whitish grayish coating. Rheumatic fever can lead to an inflammation of the heart and joint pain in addition to a skin rash. It can also be accompanied by a disorder of the gastrointestinal tract or breathing difficulties.

If the skin rash after fever occurs at the same time as diarrhoea, it is usually a drug allergy, as it often causes intestinal disorders. Thus, a drug allergy can also manifest itself through skin rash and diarrhoea. Most childhood diseases and also the three days fever can be accompanied by diarrhoea. However, diarrhoea usually does not occur at the same time as the skin rash, but before it – at the same time as the fever and other symptoms such as cough, sore throat or swelling of the lymph nodes.

Diagnosis

After a detailed discussion of the accompanying symptoms with the doctor, he can usually narrow down the possible causes.Even with childhood diseases such as measles, there is a typical localization of the rash at the beginning. In measles, for example, it usually starts behind the ears and then spreads further over the body. After the consultation, the doctor will take a closer look at the rash and can get closer to the cause through color, shape and possibly accompanying characteristics such as pustules or blisters. In the case of infectious diseases, the suspicion can be substantiated by the detection of antibodies against the respective pathogen. If the possible cause is a drug intolerance, the drug should be discontinued and the rash should then disappear.
