of pneumonia. Respiratory viruses and atypical bacteria are also responsible for causing many cases of community acquired pneumonia. Older age, history of smoking, and having comorbidities are major risk factors for contracting community acquired pneumonia. There is estimated to be an incidence rate of 1.5 to 14 cases of community-acquired pneumonia per 1000 person-years across the globe. Location, demographics, and seasons all affect the incidence rates of community acquired pneumonia. Children In 2008, pneumonia occurred in approximately 156 million children (151 million in the developing world and 5 million in the developed world). It caused 1.6 million deaths or 28–34% of all deaths in those under five years of age of which 95% occurred in the developing world. Out of all deaths of children age five and under in 2017, pneumonia was the cause of 15%, killing more children than any other infectious disease. Countries with the greatest burden of disease include: India (43 million), China (21 million) and Pakistan (10 million). Children in developing countries are at a significantly higher risk for developing pneumonia because malnutrition, overcrowding, and the lack of proper housing are prevalent risk factors. Other illnesses can also worsen the chances for developing pneumonia, such as malaria which is commonly seen in Africa and South Asia. Overall, the most determining risk factors for developing pneumonia among children in developing countries are age and the season. Children under 1 year of age are more at risk, and children overall are more at risk during rainy/wet seasons. S. pneumoniae appears to be the most prominent cause of infection, although it's unclear as to whether bacterial and viral co-infection plays a larger role in infecting children. It is the leading cause of death among children in low income countries. Many of these deaths occur in the newborn period. The World Health Organization estimates that one in three newborn infant deaths are due to pneumonia. Approximately half of these cases and deaths are theoretically preventable, being caused by the bacteria for which an effective vaccine is available. Europe Each year, Europe suffers from 230,000 deaths caused by pneumonia. Community acquired pneumonia causes more deaths in Europe than any other single infectious agent. Community acquired pneumonia has an incidence rate of 1.7-11.6 cases per 1000 people each year in Europe. The rates of community acquired pneumonia vary by country, but there is an estimated one million people hospitalized in Europe due
