My father got symptoms like fever, bodyache, mild cough after he got his second dose of Covishield. He immediately isolated himself and started on the recommended course of Azithromycin, Ivermectin,etc. It's been 11 days. He still has fever, cough and bodyache. He got HRCT chest which shows ground glass opacities and consolidation which are bilateral and predominant in basal and subpleural locations. Severity score is 11/25. His spO2 is around 94-97. What should I do? Please suggest course of action.
