The highest fever limit, based on the provided reference, is 46.5 °C (115.7 °F), although survival at this temperature is rare.
Fever is an elevated body temperature that can be a sign of illness or infection. It's important to understand the ranges of body temperatures that can become dangerous. The reference highlights specific temperature thresholds and their corresponding risks.
Critical Temperature Thresholds:
The following table outlines critical temperature thresholds related to fever and their potential consequences, based on the reference:
| Temperature (°C) | Temperature (°F) | Potential Effects |
|---|---|---|
| 42 °C | 107.6 °F | Subject may turn red. |
| 43 °C | 109.4 °F | Normally death, or serious brain damage, convulsions, and shock. Cardio-respiratory collapse is likely. |
| 44 °C or more | 111.2 °F or more | Almost certainly death will occur; however, people have been known to survive up to 46.5 °C (115.7 °F). |
| 46.5 °C | 115.7 °F | Survival is very rare. |
As you can see, temperatures above 42°C (107.6°F) become increasingly dangerous. While survival is possible even at extreme temperatures, it is not common. Temperatures reaching 43°C (109.4 °F) significantly increase the risk of severe complications and death.
Key Points:
- The reference indicates that death is almost certain at 44 °C (111.2 °F) and above.
- Survival has been recorded up to 46.5 °C (115.7 °F), although it's incredibly rare.
- Brain damage, convulsions, and shock become significant risks as temperatures reach 43 °C (109.4 °F).
- Cardio-respiratory collapse is also a likely outcome at 43 °C.
It's essential to monitor high fevers closely and seek medical attention if a fever reaches 40°C (104°F) or higher, or if other symptoms such as seizures, confusion, or difficulty breathing accompany the fever.
