Quick Answer#
Fever is usually a response to infection and often improves with rest, hydration, and symptom care. Persistent or high fever needs evaluation.
Emergency Signs#
Urgent care is needed for breathing difficulty, confusion, persistent vomiting, severe dehydration, seizures, chest pain, or very low urine output.
Common Causes#
Viral infections, bacterial infections, urinary infections, respiratory infections, and inflammatory illnesses can cause fever.
Suggested Tests#
Doctors may suggest CBC, CRP, urine routine, dengue tests, malaria tests, chest imaging, or targeted culture based on symptoms.
What To Do Now#
Hydrate well, monitor temperature, use doctor-advised fever medicine, and track associated symptoms.
When To See A Doctor#
See a doctor if fever lasts more than 2 to 3 days, crosses high ranges repeatedly, or appears in elderly, pregnant, or high-risk patients.
