New immigrants to the colonies had high death rates from their exposure to a new disease environment. However by the second generation death rates were lower than in England because there was much more food and less crowding. Becoming a regular doctor was difficult. Finally in 1765 the first medical school opened at the College of Philadelphia.
Pneumonia is a common respiratory infection, [2] affecting approximately 450 million people a year and occurring in all parts of the world. [3] It is a major cause of death among all age groups, resulting in 1.4 million deaths in 2010 (7% of the world's yearly total) and 3.0 million deaths in 2016 (the 4th leading cause of death in the world).
In 1900, the top three causes of death in the United States were pneumonia/influenza, tuberculosis, and diarrhea/enteritis. Communicable diseases accounted for about 60 percent of all deaths. In 1900, heart disease and cancer were ranked number four and eight, respectively.
Electronic health records, [87] [88] [54] death certificates [89] [56] [90] [91] as well as post-mortem analyses (such as post-mortem computed tomography and other other pathology) [92] can and are often used to investigate underlying causes of deaths such as for mortality statistics, [93] [94] relevant to progress measurements.

In 1900, the leading cause of death in the United States was influenza with 202.2 deaths per 100,000 people followed by tuberculosis with 194.4, which is a curable illness today. In the middle of 20th century America, the leading cause of death was heart disease with 355.5 deaths per 100,000 followed by cancer at 139.8 deaths per 100,000 ...

For a given epidemic or pandemic, the average of its estimated death toll range is used for ranking. If the death toll averages of two or more epidemics or pandemics are equal, then the smaller the range, the higher the rank. For the historical records of major changes in the world population, see world population. [3]
Pneumonia fills the lung's alveoli with fluid, hindering oxygenation. The alveolus on the left is normal, whereas the one on the right is full of fluid from pneumonia. Pneumonia frequently starts as an upper respiratory tract infection that moves into the lower respiratory tract. [55] It is a type of pneumonitis (lung inflammation). [56]
