Most fevers are caused by infections the body can fight off on its own within a few days.
At home, rest, fluids and paracetamol as directed usually help. Watch the overall condition more than the exact temperature number.
Seek medical care if the fever lasts more than three days, crosses 103°F, or comes with severe headache, breathlessness, persistent vomiting, a rash, or confusion.
For infants, the elderly, and people with chronic illness, it's best to consult early. A home visit is a convenient option when travelling to a clinic is difficult.
