About 38.4°C / 101.12°F: Temperature Facts and Applications
38.4°C (101.12°F) is considered a moderate fever in both adults and children. Normal body temperature typically ranges from 36.5°C to 37.5°C (97.7°F to 99.5°F). A temperature of 38.4°C indicates a moderate elevation and may require monitoring or medical attention depending on the individual's age and other symptoms.
In medical settings, monitoring body temperature is crucial for diagnosing illnesses. A fever can be a sign of infection, inflammation, or other underlying health issues. If a fever persists or is accompanied by other symptoms, it's important to consult a healthcare provider.
Practical Applications of 38.4°C (101.12°F)
38.4°C (101.12°F) is a significant temperature in medical diagnostics. It is often used as a threshold to determine if a patient has a moderate fever:
- Pediatrics: In children, a fever of 38.4°C may require monitoring and possibly medical attention if it persists or is accompanied by other symptoms.
- Adults: While adults can tolerate fevers better, a 38.4°C fever may still indicate an infection or illness that needs attention.
- Underarm Measurement: Note that underarm (axillary) temperatures are typically 0.5-1°C lower than oral temperatures, so a 38.4°C reading under the arm may correspond to a higher core body temperature.
