What should I do if my baby develops many red spots after having a fever?

Generally speaking, fever refers to an elevated body temperature. If a baby develops red spots on the body after a fever, it may be related to conditions such as heat rash, drug rash, infantile exanthema, rubella, or urticaria. It is recommended to seek timely medical attention and follow the doctor's guidance for treatment, which may include general care and medication. Detailed explanations are as follows:

1. Heat Rash

Heat rash is a skin inflammation caused by blocked sweat glands. When a baby has a fever, excessive clothing or a high ambient temperature may prevent sweat from being excreted normally, potentially causing a rash on the skin. It is recommended to dress the baby in lighter clothing and use breathable bedding materials.

2. Drug Rash

Drug rash is a skin reaction caused by an allergic response to certain medications. If a baby takes antibiotics, antipyretics, or analgesics during a fever, a drug rash may develop. It is recommended to use medications with simple compositions and high safety profiles, and to closely monitor the baby's reaction.

3. Infantile Exanthema

Infantile exanthema is a common physiological rash that appears after a fever in babies. Following a viral infection, the baby's immune system produces antibodies to fight the virus, which may lead to the appearance of a skin rash. It is recommended to appropriately introduce complementary foods and administer vaccinations on schedule to enhance the baby's immunity.

4. Rubella

Rubella is an acute respiratory infectious disease caused by the rubella virus. The virus spreads through droplets and can cause swollen lymph nodes and a rash after infection. It is usually accompanied by symptoms such as headache, joint pain, and fatigue. Medications such as acetaminophen tablets, ribavirin tablets, or famciclovir tablets may be used under medical supervision for treatment.

5. Urticaria

Urticaria is typically caused by the measles virus. The virus spreads through droplets, causing high fever, followed by the appearance of a rash after the fever subsides. Symptoms generally include photophobia, tearing, and Koplik spots in the oral mucosa. Antihistamine medications such as cetirizine tablets, loratadine tablets, or dexamethasone tablets may be used under a doctor's guidance for treatment.

In daily life, it is important to appropriately introduce complementary foods to ensure balanced nutrition for the baby. Additionally, regular outdoor activities can help strengthen the baby's overall physical condition.
