HI Well come to HCM Thank for asking to HCM your health concern will be appreciated, I had gone through the history given here and let me inform you that until and unless it is being diagnosed clinically or tested and confirmed malaria and typhoid it can not be said that one, of course it could be febrile condition, if the temperature is above 100 F then it is the high grade fever, in febrile state the most important is to take care of hydration else you can have any light diet avoid taking spicy, oily greasy, fat contained food, have more vegetable diet fresh fruits it is all. It may be viral infection, just wait for couple of days and it will be fine, if not then you will have to see the doctor. hope this information helps.
