What body temperature is considered a fever?

For adults, 100.4°F (38°C) or higher is typically a fever. But please, if you're not feeling well or if it stays high for more than a day or two, or if you have other symptoms, go see a doctor. I once thought it was just a mild fever and ended up with a bad infection, so it's always better to be safe.

I totally get why you're asking this. When I had dengue, my temperature kept fluctuating and it was so confusing. My doctor said anything over 100°F is a fever, but more importantly, how you *feel* matters. If you feel really unwell, that's the main thing.

Usually, above 100°F is what we consider a fever at home, and my mother always said a little warm water and rest helps. But honestly, if you're feeling really sick or if the temperature keeps going up, it's best to consult a doctor. They can tell you exactly what's going on. Don't worry too much.

My doctor always tells me that for most people, a temperature above 100.4°F (38°C) is counted as a fever. But if you have any underlying conditions, like thyroid issues or diabetes, it's good to talk to your doc about what to watch out for specifically. Sometimes things can react differently for us.
