This study explains about the Intense lower respiratory plot diseases (ALRI), including pneumonia and bronchiolitis, were answerable for an expected 650 000 passings of youngsters under five years of age in 2016 and keep on being a significant reason for baby dreariness and mortality worldwide.1 Multiple infections cause respiratory ailment in kids, including flu, respiratory syncytial infection (RSV), rhinovirus, enterovirus, and adenovirus.2 Influenza is among the most widely recognized etiologies of ALRI scenes and is liable for an expected 39 million cases every year among the two kids and grown-ups. An expected 30 000-100 000 kids under 5 years of age kick the bucket from flu every year, with 99% of these happening in creating countries.3 RSV is answerable for more than 33 million new instances of youth ALRI every year, and an expected 55 000 to 190 000 passings of kids under 5 years of age can be ascribed to ALRI from RSV alone.4 Multiple infections are frequently at the same time distinguished, however the effect of coinfection isn’t clear cut. Further, little exploration has been done to analyze viral coinfection in low asset settings. 

Counteraction of dreariness and mortality because of respiratory viral sickness stays a significant objective around the world. At present, occasional flu antibodies are broadly accessible, and fostering a RSV antibody is among the essential 2020-2025 objectives for GAVI (Global Alliance for Vaccines and Immunization) and the WHO.
