Overview
- The incidence of pneumonia can be affected by factors relating to the geography, especially in regards to fungal pneumonia[1], as well as seasonal variations. Studies show that a majority of Streptococcus pneumoniae cases were most prevalent during the winter, whereas far fewer cases presented in the summertime in comparison.[2]
Incidence
- Approximately 5 million people are affected every year in the United States alone, with outpatients making up the majority at 80% but having a low mortality rate of 1%. Up to half of the patients that are admitted into hospitals succumb to the disease.[3]
- Worldwide, the incidence of community acquired pneumonia averages 1.5-14 cases per every 1000 individuals.[1]
- The incidence in the United States is approximately 25 cases per 10,000 adults.[1]
