Fever

Elevation of body temperature above normal (>100.4°F/38°C), usually a sign the body is fighting an infection. The most common causes include: Bacterial/viral infections; Inflammation; Autoimmune disorders; Heat stroke.

Fever becomes an emergency when it is unusually severe, sudden in onset, accompanied by other serious symptoms (chest pain, difficulty breathing, fainting), or occurs in vulnerable individuals such as infants, the elderly, or people with serious chronic conditions.

Diagnosis of Fever begins with a detailed medical history and physical examination of the body. Your doctor may order blood tests, urine analysis, imaging studies (X-ray, ultrasound, MRI), or refer you to a specialist depending on suspected causes. Early diagnosis leads to faster, more effective treatment.

Mild cases of Fever can often be managed with self-care: Rest; drink plenty of fluids; lukewarm sponge bath. However, if symptoms are severe, persistent, or worsening, always seek medical attention rather than relying solely on home remedies.

Fever is typically classified as days. Acute forms usually resolve within a few days to weeks with appropriate care. Chronic or recurrent fever may persist for months and requires longer-term management by a healthcare professional.

You should see a doctor if: If >103°F in adults; >100.4°F in infants <3 months; lasting >3 days. Early evaluation by a healthcare professional ensures an accurate diagnosis and prevents complications.
