Pneumonia remains a major killer of young children in India, being the leading infectious cause of under-five deaths, with hundreds of thousands of deaths annually, though efforts are ongoing through government programs (like revised 2019 guidelines) and interventions focusing on vaccination (PCV), better nutrition (breastfeeding, complementary feeding), hygiene, and addressing pollution, with significant regional variations and persistent challenges like antibiotic resistance and access to care, particularly in high-burden states like UP and MP.
