Overview[edit | edit source]
Intermittent fever is a type of fever pattern where the body temperature fluctuates between periods of fever and periods of normal or subnormal temperature. This pattern is often associated with certain infectious diseases and can provide clues to the underlying cause of the fever.
Characteristics[edit | edit source]
Intermittent fever is characterized by:
- Fever spikes: Periods of elevated body temperature that occur at regular intervals.
- Afebrile periods: Intervals where the body temperature returns to normal or below normal.
The duration and frequency of the fever spikes can vary depending on the underlying condition.
Causes[edit | edit source]
Intermittent fever can be caused by a variety of conditions, including:
- Malaria: A parasitic infection transmitted by mosquito bites, known for its classic tertian (every 48 hours) or quartan (every 72 hours) fever patterns.
- Tuberculosis: A bacterial infection that can cause prolonged intermittent fever.
- Sepsis: A severe infection that can lead to intermittent fever as the body attempts to fight off the infection.
- Brucellosis: A bacterial infection from animals that can cause undulant fever, a type of intermittent fever.
Diagnosis[edit | edit source]
The diagnosis of intermittent fever involves:
- Medical history: Understanding the pattern of fever and any associated symptoms.
- Physical examination: Checking for signs of infection or other underlying conditions.
- Laboratory tests: Blood tests, cultures, and imaging studies to identify the cause of the fever.
Management[edit | edit source]
The management of intermittent fever focuses on treating the underlying cause. This may include:
- Antibiotics: For bacterial infections such as tuberculosis or brucellosis.
- Antimalarials: For malaria, specific medications are used to target the malaria parasite.
- Supportive care: Including hydration, antipyretics, and monitoring of vital signs.
Prognosis[edit | edit source]
The prognosis of intermittent fever depends on the underlying cause and the timeliness of treatment. Early diagnosis and appropriate management can lead to a favorable outcome in many cases.
