What should I do if a 20-month-old baby has a fever of 38°C?

Generally speaking, fever refers to an elevated body temperature. A body temperature of 38°C in a 20-month-old infant may be related to factors such as excessively high environmental temperature, strenuous physical activity, upper respiratory tract infection, infantile emergency rash (roseola), pneumonia, and other causes. Appropriate symptomatic treatment or medication should be promptly administered based on the underlying cause. If symptoms persist, timely medical consultation is recommended. Detailed analysis is as follows:

1. Excessively High Environmental Temperature

If the infant lives in an environment with excessively high temperature, the body's heat dissipation may slow down, causing a fever. This is a normal phenomenon and generally does not require special treatment. The symptoms can gradually improve by promptly adjusting the living environment.

2. Strenuous Physical Activity

Infants who engage in vigorous physical activity may experience a temporary increase in body temperature due to accelerated metabolism. This is a common occurrence and does not require specific treatment. However, it is important to regulate the intensity and amount of physical activity accordingly.

3. Upper Respiratory Tract Infection

Upper respiratory tract infections are respiratory diseases caused by bacterial or viral infections. When inflammation stimulates the body, it may lead to fever, often accompanied by symptoms such as coughing and runny nose. Prompt treatment with medications such as antiviral granules, amoxicillin-clavulanate potassium dry suspension, and paracetamol oral solution should be administered under a doctor's guidance.

4. Infantile Emergency Rash (Roseola)

Infantile emergency rash is caused by infection with human herpesvirus 6. The virus may stimulate the body and cause fever, often accompanied by symptoms such as red skin rashes and itching. Timely treatment using medications such as ibuprofen suspension drops, calamine lotion, and ribavirin granules should be administered strictly following a doctor's instructions.

5. Pneumonia

Pneumonia is a lower respiratory tract infection, commonly caused by bacterial or viral infections. Pathogens can affect the body's heat dissipation mechanisms, leading to elevated body temperature. Symptoms such as coughing and sputum production may also occur. It is recommended to follow a doctor's guidance for treatment using medications such as cefixime granules, ambroxol hydrochloride oral solution, and ibuprofen suspension.

It is advised to identify the cause of the infant's fever before developing an appropriate treatment plan to avoid delaying treatment. Additionally, maintaining a suitable indoor temperature is important, avoiding extremes that may affect the management of the condition.
