The rash is just an abnormality of the skin, and the deeper factors need further judgment. There are many possible reasons for a rash to appear on your body after a fever. When this happens, the key is to find the specific cause and solve it accordingly so as to eliminate the abnormality as soon as possible. So, what is the cause of the rash on the body after a fever? Let’s take a closer look at the reasons below.

There are many reasons why a rash appears on the body after a cold or fever. We should first understand the following causes and treat them in a targeted manner:

(1) Caused by drug allergy . When we have a cold or fever, we often need to take some antipyretics and cold medicines. However, due to different personal constitutions, we may have allergic symptoms to the above medicines. Once allergic, we may develop a rash on our body after taking the medicine. If the rash is caused by drug allergy, we should stop taking the medication immediately. Generally, the rash will automatically disappear within a short time after stopping the medication. If it still does not disappear within 3-5 days, you should go to the hospital for medical treatment in time.

(2) Caused by cold and fever caused by viral infection . The rash that appears on the body after a cold and fever is most likely caused by a viral infection, which can also cause rashes on the body. There is no need to worry too much at this time. The rash will disappear automatically within one to two days after the cold and fever is cured. All we have to do is keep our body clean and hygienic, pay attention to a light diet and eat more vegetables and fruits. If necessary, you can take antiviral oral liquid or some heat-clearing and detoxifying drugs.

(3) Infectious diseases . If a young child develops a rash after catching a cold and having a fever, it may be a symptom of fever caused by an infectious disease, such as chickenpox, rubella, etc. At this time, it must be taken seriously and the child must go to the hospital for medical treatment in time.

The complications caused by a cold and fever may be serious or minor. If the symptoms are serious, you must go to the hospital for treatment in time, but we cannot ignore those with mild symptoms. Although the rash on the body is not serious, the disease is superficial. When we find the cause, we must treat it in time to ensure our health.
