- 7. Approach 1. History • Age •Duration(common causes) Short (< 2 weeks) Prolonged ( >2 weeks) • Respiratory infections • Viral Infections • UTI • Malaria • Meningitis • TB • Autoimmune: JRA, SLE • Malignancy • Chronic Kalazar/ Malaria
- 8. • Character – Continuousfever : Daily fluctutation in the temperature do not exceed 1 C /24 hr and never touches baseline. Eg- Enteric fever, Pneumonia – Remittent fever : Daily fluctuations exceed 1 C and never touches baseline. – Intermittent fever: Temperature touches baseline in between febrile phases. 1. Quotidian fever: Occurs daily eg- P. falciparum 2. Tertian fever : Occurs alternate day eg- P. vivax,P. malaria 3. Quartan fever : Occurs every third day eg- Plasmodium malariae
