Introduction
A mild fever after a burn may be a physiological stress response and generally carries low risk. If the burn is minor (such as a small area of superficial burn), body temperature remains below 38°C, and there are no signs such as wound redness, swelling, pus formation, or lethargy, the fever is likely due to the body's healing process. In such cases, symptoms can usually be relieved with physical cooling measures and adequate fluid intake. The risk is low, and close observation is sufficient.
Generally, a mild fever after a burn may be a normal stress response of the body and poses a low risk. However, if there is high fever or accompanying abnormal symptoms, there may be a risk of infection, which requires caution. If in doubt, it is advisable to seek medical advice promptly. Detailed analysis is as follows:
If the burn is minor (such as a small area of superficial burn), with body temperature below 38°C and no signs such as wound redness, swelling, pus, or lethargy, the fever is usually a stress response during the body's healing process. It can be relieved through physical cooling and adequate hydration. This situation carries a low risk and only requires close observation.
If the burn covers a large area or is deep, with fever exceeding 38.5°C, accompanied by increased wound discharge, foul odor, redness and swelling of surrounding skin, or symptoms such as chills, fatigue, and loss of appetite, it may indicate an inflammatory response caused by wound infection. Without timely treatment, the condition could worsen, posing a certain level of danger.
After a burn, it is essential to keep the wound clean and dry to avoid contamination. Monitor body temperature regularly when fever occurs and record any symptoms. Seek immediate medical evaluation if high fever or unusual signs develop, to determine the cause and receive professional treatment, preventing deterioration of the condition.
