Ahhh sabar ye mama, memang adenovirus ni jenis virus yang pelik-pelik sikit. Dari what I hear dari mum group, demam on-and-off boleh berlangsung 3-8 hari even after blood test normal, yang penting blood count dah okay, so that's a relief already. Since doc dah discharge dia, I think the worst has passed, tapi memang frustrating tengok anak demam terus kan. Make sure you monitor closely untuk sesak nafas or anything unusual, and don't hesitate to go back if anything changes, your instinct as a mum is important. Hang in there, sabar sikit lagi insyaAllah get better!
