Thanks for posting.
Well if your daughter seems to develop humor disorder is probably as a result of either the fact that she is recovering from her infection or the fact that she has developed complications. Recovery phases from infection, even though most at times is characterized by improved appetite, good mood etc it can also be characterized by negative mode swings and hyper activity. My suggestion is that you should allow your daughter some few days to actually recover completely. If she is persistent with the aggressiveness, agitation and altered mental status, then you should probably see a doctor urgently as that could be a complication of the viral fever
are potent possible complications.
For now, there is no cause for alarm. Just give her some few days and she will be fine.
