4. Association of recurrent upper respiratory tract infections with low production of oxygen intermediates in children
Abstract Objectives: Upper respiratory tract infections in children generally have significant morbidity and mortality. There is little data available about functional immaturity of the immune system and the child’s susceptibility to infections at the beginning of their lives, thus, justifying a more specific immunological analysis. Method: Analysis of h
