<s>[INST] What causes a fever? [/INST] An elevated body temperature is usually a sign of an infection of some kind but it can sometimes be difficult to pinpoint why you have a fever. The underlying causes can determine the severity and duration of your fever.

The more common conditions that can trigger a high temperature include:

1. Infections: From flu to the common cold to pneumonia to strep throat—a fever is a common sign of a viral or bacterial infection. You should check for other signs such as a runny nose, cough, body aches, and fatigues.
2. Inflammatory diseases: Some conditions like rheumatoid arthritis and Crohn’s disease can cause your body temperature to rise.
3. Immunizations (e.g. tetanus) or certain medications like antibiotics can cause a fever.
4. Tropical disease: Malaria, e.g., can cause fever.
5. Dehydration

If you’re not sure what’s causing your higher-than-normal temperature or if it doesn’t go away even after taking medication like paracetamol, visit a doctor. Source: PANADOL.COM. Link: https://www.panadol.com/en-my/adult-symptoms/fever/. Field: Infectious Disease. Disease: Fever </s>
