Persistent fever in adults can result from viral, bacterial or parasitic infections, inflammatory conditions and other underlying illnesses. Fever lasting several days, returning repeatedly or remaining unexplained needs medical assessment. An infection specialist doctor investigates possible infectious causes through examination and suitable tests. Dr Yash Khatod provides specialised fever and infectious disease consultations in Jaipur, including Sitapura and Malviya Nagar, helping patients understand diagnosis and treatment options.
What are the common causes of persistent fever in adults?
The causes of persistent fever in adults include infections, inflammatory disorders, medicine reactions and other health conditions requiring investigation.
- Viral infections: Influenza and other viruses commonly cause fever, tiredness and body aches.
- Bacterial infections: Pneumonia, tuberculosis and urinary infections may produce prolonged or recurring fever.
- Tropical infections: Malaria, dengue and typhoid are important considerations in India, depending on exposure and symptoms.
- Inflammatory conditions: Autoimmune disorders can cause fever through persistent inflammation.
- Medicine reactions: Certain prescribed medicines occasionally trigger fever, requiring medical review.
Doctors consider symptoms, travel history, examination findings and previous illnesses before selecting investigations.
When should adults worry about continuous fever?
Adults should seek medical assessment when fever persists beyond three to four days, worsens or appears alongside concerning symptoms.
- Continuous fever for 3 days: Contact a doctor when fever persists, particularly with worsening symptoms or existing medical conditions.
- Persistent fever for 5 days: Further examination may help identify an infection or underlying illness.
- Repeated fever: Fever returning after improvement may need review of earlier diagnoses and treatments.
- Emergency symptoms: Confusion, breathing difficulties, severe headache with neck stiffness or fainting require immediate hospital care.
- Higher risk patients: Older adults and people with weakened immunity may require earlier assessment.
