For a 7 yr old kid, the weight gain is inadequate, and he falls sick frequently; all along he had many viral, parasitic as well bacterial infections. Hygiene is very important in handwashing, toilets as well eating and Chat Doctor.  I suggest screening for TB and proper clinical examination including blood tests and ultrasound test of the abdomen are needed. A proper dietician help would warrant for appropriate calories and protein intake for him.
