Persistent fever after viral
My father (55 years) had continuous fever for about 14 days with chills. He was treated with antivirals, antibiotics, IV fluids and IV steroids. Initially oxygen dropped to 85–88% while lying and 90–92% while sitting. Over the last few days oxygen has improved to 92–95% while sitting and reaches 96–98% with deep breathing. CT chest showed bilateral lung inflammation. Dengue, typhoid, blood culture and urine culture are all negative. ECG is normal.
Latest blood report (13-01-2026):
WBC: 4500 (normal)
Platelets: 3.46 lakhs (normal)
ESR: 63 (high)
Total bilirubin: 2.2
Direct bilirubin: 1.2
SGOT: 86
SGPT: 64
ALP: 221
Albumin: 3.3
Random sugar: 324 (after steroid)
Urea and creatinine normal
Fatty liver present
Doctor says blood and liver values are improving after reducing medicines and patient is in recovery stage. However fever still comes mainly at night (100–101°F) and settles with paracetamol.
My questions:
Is it normal for fever to continue like this during recovery ?

Yes — it can be normal for low-grade fever (especially at night) to persist during the recovery phase, given your father’s clinical picture.
Based on the information:
• He had significant bilateral lung inflammation (likely viral or post-viral pneumonitis)
• Oxygen levels are clearly improving
• Infection markers (WBC, platelets) are normal
• Cultures for dengue, typhoid, urine, blood are negative
• Liver enzymes and bilirubin are elevated but trending down
• ESR is high, which reflects ongoing inflammation, not necessarily active infection
In such cases, post-infectious inflammatory fever is common. The body’s immune system remains activated even after the infection is controlled, leading to:
• Evening or night-time fever
• Fatigue and weakness
• Raised ESR
This can last 2–4 weeks, sometimes longer, especially after severe lung involvement.
Importantly, the pattern you describe — fever settling with paracetamol, improving oxygen, stable vitals — supports recovery rather than worsening disease.
Next Steps
1. Continue close monitoring, not panic treatment:
• Daily temperature chart
• Oxygen saturation (especially at rest and on walking)
2. Repeat labs after 7–10 days (as advised by the treating doctor):
• LFTs
• ESR / CRP
• Blood sugar monitoring (steroid-induced hyperglycemia is common)
3. Chest follow-up (X-ray or CT only if symptoms worsen)
4. Seek re-evaluation urgently if:
• Fever spikes >102°F
• Oxygen drops again
• New cough, breathlessness, chest pain, confusion
• Jaundice worsens
At this point, aggressive antibiotics or antivirals are not usually needed unless new evidence appears.
Health Tips
• Encourage adequate hydration and protein intake (albumin is slightly low)
• Light breathing exercises and incentive spirometry help lung recovery
• Avoid alcohol and heavy fatty food (fatty liver + raised LFTs)
• Control sugars strictly for now — steroid-related spikes usually settle
• Ensure good sleep; fever often rises at night due to normal immune rhythms
From what you’ve shared, your father’s course looks like a gradual but genuine recovery, not a missed infection. Persistent low-grade fever during healing from lung inflammation is well-recognized and usually self-limiting. You’re doing the right thing by observing trends rather than reacting to single readings.
If you’d like, I can also help you understand how long lung recovery typically takes and what signs truly indicate a setback versus normal healing.

From the reports and history, this looks like a post-viral / inflammatory recovery phase (especially with lung involvement). Night fevers of 100–101°F can happen for a short while during recovery. ESR being high supports ongoing inflammation. Liver values are mildly raised (likely illness + medicines + fatty liver). Oxygen improving is a good sign.
Next Steps
• Continue current treatment as advised
• Keep monitoring temperature + oxygen
• Repeat CBC, CRP/ESR and LFT in 5–7 days
• Good hydration + light diet
• If fever persists beyond another 5–7 days or rises >101°F, review urgently with physician / pulmonologist

Yes, this pattern of fever can be normal during recovery,That is steroid-induced hyperglycemia and should come down after stopping steroids — but it must be monitored, as high sugars can delay recovery and prolong inflammation.
