I. Introduction:
Pneumonia is a frequent disease brought on by many microorganisms like bacteria, viruses, and fungus. The term “pneumonia” is procured from the Greek word “pneumonia,” which means “lungs.” The connection between lungs and the name pneumonia thus leads to name the diseases associated with lungs as pneumonia. Inflammation may be a symptom of the infection in one or both lungs that is brought on by pneumonia [1]. Additional causes of pneumonia, however, comprise of food aspiration and chemical compound exposure. Depending on the infection, the root of pneumonia is pathogen-induced inflammation that causes the lung's alveolus to fill with fluid or pustule, resulting in a decrease in carbon-dioxide and oxygen circulation between blood and the lungs, making it hard for people who are infected to breath. Shortness of breath, fever, cough, chest pain, and other symptoms of pneumonia are common. Furthermore, persons at risk of pneumonia include the elderly (those over the age of 65), children (those under the age of five), and those with additional difficulties such as HIV / AIDS positive, diabetics, lung disorder and pulmonary disease, cardiac arrest, cancer, liver disease, and so on [2]. For many people, the danger of pneumonia is enormous, particularly in underdeveloped countries where large number confront energy poverty and rely on polluting kinds of energy. The WHO evaluate that home air pollution-related diseases such as pneumonia cause approximately 4 million premature deaths each year. Every year, about 150 million individuals become infected with pneumonia, the majority of them are children under the age of five [3]. A potentially fatal infection, pneumonia aggravating the most recent coronavirus disease in 2019 (COVID-19), will kill thousands of people in 2020 [4]. In India, the mortality rate due to pneumonia is very high [5]. The death due to respiratory disease in India from 2010–2022 is reflected in Figure 1.
