Fever returning every 5-6 hours for three days with headache, sore throat and cough is most often a viral infection, but at this stage dengue, typhoid, malaria and influenza all need to be ruled out â three days is the point where blood tests become meaningful rather than guessing. Paracetamol 650 mg is a reasonable fever medicine and you may continue it as needed, but I would not add antibiotics or any other tablet without a diagnosis. Drink plenty of fluids, take steam inhalation and warm saline gargles for the throat, and rest. Please watch for warning signs: breathlessness, persistent vomiting, bleeding from gums or nose, severe abdominal pain, rash, drowsiness or fever above 103°F not settling â any of these need emergency care the same day.
Next Steps
Please get these tests today: CBC with platelet count, dengue NS1/IgM, malaria smear or rapid test, typhoid (Widal/Typhidot),
CRP and urine routine. Show the reports to a physician the same day so treatment can be targeted rather than trial and error. You are welcome to book a teleconsult with me on Practo once the reports are ready, or see me at Synergy Multispeciality Hospital, Miraj (consultation fee Rs 100).
