Symptoms of primary complex and what happens to a primary complex child

is there such skin allergy which caused by insect bites?

If you are referring to the Primary Complex associated with the tuberculin bacteria, I've attached several web links that detail the treatment of a child with this condition (see below).

In general, most children will receive a course of antitubercular drugs (ioniazide, rifampin, ethambutol, pyrazinamide, and sometimes others) to combat and suppress the initial infection. Treatment usually continues for approximately 6 months, but may be extended for up to a year.
