Overview
A fever is a body temperature of 38°C (100.4°F) or higher. It is usually a sign that the body is fighting an infection, such as a cold, flu, throat or ear infection. Most fevers settle within a few days. In Pakistan, dengue, malaria and typhoid are also important causes to keep in mind.

- Viral infections such as colds and flu
- Bacterial infections (throat, ear, chest, urine)
- Dengue, malaria and typhoid
- Reactions after vaccination

Risk factors
- Young children and older people are more affected
- Weak immunity

Diagnosis
Temperature is measured with a thermometer. If the fever lasts or is high, your doctor may order a blood count, dengue, malaria or typhoid tests, or a urine test.
Management
