hello everyone, I was COVID positive last year in the month of May, my daughter was staying with me.she also had fever that time , now she is going to school but she is suffering from cold, and fever more offen, it's almost twenty days that she is falling ill, I have given her amoxy clav, solvin cold , but after that she was fine for a week and now again she is suffering from cold and fever as there are students of her class having cold and fever. I think her immunity has become weak that's why falling ill. suggest what to do.
