Thanks for the query
As you have mentioned all reports were normal and only fever was there which was also of only moderate grade, it seems that he has become just a victim of injudicious usage of antibiotics. During the course of 4 days only without any other severe symptoms and with normal reports usage of 4th generation cephalosporine like cefepime
is really unjustified. It may be viral fever
which subsided over few days or may be malaria
as he has also received antimalarial. You need not to worry as such short course of antibiotic usually does not have any effect on body.
I hope this answers your query effectively
