Community-acquired pneumonia is the acute infection lung tissue infection in a patient who established it in the community or within 48 hours of admission to the hospital. and accounts for a significant proportion of the acute lower respiratory infection disease burden. The treatment strategies used in the management of community-acquired pneumonia are Antibiotics, Bronchodilators. The current study aims to find out the bacterial pathogens associated with community-acquired pneumonia. This review discusses the common pathogens found in community-acquired pneumonia in children below twelve years. Various treatment strategies are also discussed in view of identifying the pathogens of community-acquired pneumonia. Depending on the pathogens and age of the patient’s antibiotics were selected. The author discusses recent patents relating to the treatment of community-acquired pneumonia. Generally, Haemophilus influenza is the most common cause of community-acquired pneumonia in children younger than 5 years. The most common bacterial cause is Streptococcus pneumonia, which affects people of all ages. On clinical grounds, bacterial and viral pneumonia cannot be consistently differentiated in the majority of cases. In fact, most children with pneumonia are treated with antibiotics on a case-by-case basis. © 2022 Elsevier B.V., All rights reserved.
