What causes small red spots on a child's face after a fever, and what should be done?

Generally, after a child develops a fever, small red spots on the face may be related to factors such as heat rash, eczema, roseola infantum, rubella, or measles. It is recommended to implement general treatment or medication timely according to the underlying cause to alleviate symptoms. If symptoms persist for a prolonged period, medical attention is required. Detailed analysis is as follows:

1. Heat Rash

Heat rash is commonly associated with overheating. In hot weather, when sweat glands do not excrete properly, sweat may become trapped beneath the skin and cause small red spots during fever. Symptoms may include skin irritation and redness. Treatment should follow medical advice using medications such as camphorated oil, essential balm, or calamine lotion.

2. Eczema

Eczema typically relates to contact allergens or external irritants. When the condition is severe, it may cause skin rashes, fever, red patches, and itching. The allergen should be avoided promptly, and treatment should follow a doctor's guidance using medications such as mometasone furoate cream, halometasone cream, or ebastine oral solution.

3. Roseola Infantum

Roseola infantum is caused by infection with human herpesvirus 6. Viral stimulation can cause fever and skin rashes, possibly accompanied by symptoms such as loss of appetite and swollen lymph nodes. Treatment should follow a doctor's recommendation using medications such as ribavirin granules, acyclovir cream, or paracetamol oral solution.

4. Rubella

Rubella is caused by the rubella virus. During the acute phase, symptoms such as fever and skin rashes may appear, often accompanied by swollen lymph nodes behind the ears and at the back of the head. After diagnosis, treatment should follow a doctor's instructions using medications such as ganciclovir for injection, recombinant human interferon α2b for injection, or Pudilan anti-inflammatory oral liquid.

5. Measles

Measles is a contagious disease caused by the measles virus. During the acute phase, it can cause the aforementioned discomforts, often accompanied by coughing and rapid breathing. Prompt treatment following medical advice using ribavirin injection, acyclovir injection, or Feilikke Syrup is recommended.

It is recommended to first determine the cause and severity of the child's fever before selecting an appropriate treatment method. Additionally, proper skin hygiene and care during treatment are important to reduce the risk of infection.
