Real time identification of common pathogens causing acute respiratory tract infection in children below 14 years of age and role of vitamin D supplementation in reduction of ARTI

This study is a stratified randomized control trail in which participants are selected based on the inclusion and exclusion criteria. Identification of various pathogens responsible for ARTI in children below 14 yrs of age and percentage of bacterial, viral and bacterial - viral coinfection will be calculated. The level of vitamin D and Interleukin 6 (IL6) in serum will be checked and the participants with vitamin D deficiency and insufficiency will be identified. The participants where divided into three groups (No Pneumonia, Pneumonia and Severe Pneumonia) based on the symptoms and each group will be divided into two groups (Intervention & Control) based on the vitamin D deficiency and insufficiency. The intervention group will receive vitamin D supplement 60000 IU, weekly once for 3 months. patients will be followed up during their intervention. After a period of 3 months of intervention, the serum Vitamin D, IL6 level and the Persistent infection will be checked. Primary outcome will be the identification of various pathogens and calculation of percentage of each pathogen and its coinfection will be assessed. Secondary outcome is the level of vitamin D is associated with the severity of infection / helps in the reduction of recurrent infection.
