- You aren’t considered to have a fever until you get to 100.4. Anything less than that isn’t considered a fever, let alone a concerning one
- A fever isn’t considered concerning (ie dangerous) until it reaches about 104. Anything between 100.4 and 104 is just a regular fever and isn’t considered concerning.
- You aren’t considered to have a fever until you get to 100.4. Anything less than that isn’t considered a fever, let alone a concerning one
- A fever isn’t considered concerning (ie dangerous) until it reaches about 104. Anything between 100.4 and 104 is just a regular fever and isn’t considered concerning.
