A. in diagnosing allergic cough and cold, the child experiences regular cough and cold without fever, which fluctuates but doesn't fully resolve. treatment typically includes anti-allergic medications like montelukast or levocetirizine. if there's no improvement, inhaler therapy with mdi or a nebulizer is considered. allergies can be triggered by environmental factors (temperature changes, dust, smoke, pollens), certain foods, preservatives, and sweets. these allergies often cause symptoms in the evening, night, or morning. d
