Step 4: Read and complete the decision guide to learn more about your symptoms.

Fever in Adults

You've reached the end of this guide. We hope the cause of your fever is discovered quickly and that you're back to normal soon.

Remember -- there are many causes of fever. Here are some of the more common causes of fever covered in this guide:

- Bacterial infections, such as meningitis, strep throat, urinary tract infection, or pneumonia

- Viral infections, such as the common cold, mono, or "stomach flu"

- Pulmonary embolus (blood clot in the lung)

- Medication reaction (called drug fever)

- Rheumatic diseases, such as lupus or vasculitis

- Exposure to environmental heat (as with heat exhaustion or heat stroke)

If the cause of your fever is not covered here or if your symptoms don't respond to treatment, be sure to see your doctor for evaluation (or re-evaluation). It may be helpful to see a specialist about an unexplained persistent fever. For example, infectious disease specialists often see patients for "fever of unknown origin" (FUO).

We hope you feel better soon!
