His experience over last 2 days: 1) some cough on 05/09 afternoon, probably due to heavy dust while driving to office. He did wear mask though. 2) Slight feverish/weakness the same afternoon, but vanished in half an hour. 3) Focused headache in right side of head the same evening for about an hour 4) Weakness striked at a sudden last night around 11 pm, had proper food around 9, and milk after weakness came in. Checked for fever, found nothing, though the temp was below normal. Have been with same weakness till now, no sign of tiredness though.
