Persistent Fever: Common Causes and When to Seek Medical Advice

Fever is the body's natural response to infection, and most fevers — especially viral ones — settle within three to five days with rest, fluids and simple supportive care. But in Bhopal, we also see fevers due to dengue, malaria, typhoid and other infections that need specific testing and treatment. Knowing when a fever needs a doctor makes all the difference.

Common causes of fever in adults

• Viral infections (including seasonal flu and viral fevers)
• Dengue, malaria and chikungunya — especially in and after monsoon
• Typhoid (enteric fever) — typically a prolonged, sustained fever
• Urinary tract infections
• Respiratory infections, including pneumonia
• Less commonly, tuberculosis and non-infective causes

Sensible home care while you monitor

Rest, adequate fluids, light food and temperature recording two to three times a day are reasonable. Avoid self-medicating with antibiotics — they do not work against viral fevers and can mask or complicate other illnesses. Avoid combining multiple painkiller brands, as many contain the same ingredient.

When to seek medical advice

• Fever beyond 3 days, or fever that keeps returning
• Temperature above 103°F (39.4°C) that does not settle
• Fever with severe headache, vomiting, rash, bleeding gums or reduced urine
• Breathlessness, chest pain, confusion, extreme weakness or stiff neck
• Fever in someone with diabetes, kidney disease, low immunity, pregnancy, or in the elderly

What the doctor will typically do

A physician will examine you, ask about travel, food and water exposure, and order targeted tests — such as a blood count, malaria/dengue tests, typhoid test or urine examination — based on the pattern. This avoids both under-testing and unnecessary testing, and ensures the right treatment rather than guesswork.

If your fever has persisted beyond a few days or comes with any warning sign, do not wait it out — get evaluated.
