Background: One of the prime global health problem in children is pneumonia accounting for 29% of mortality worldwide. One of the important micronutrient in humans which plays vital role in stimulation and proper functioning of immune system and prevents infections is zinc. There is a strong correlation between risk of pneumonia in a population with zinc deficiency with high rates of infections such as diarrhea, skin, and respiratory infections. The prime objective of present study is to provide further experimental support to strengthen above correlation. To study the serum zinc levels in children hospitalised with pneumonia and correlation between serum zinc levels and severity of pneumonia and its complications.
