Pneumonia is the leading cause of death in children younger than 5 years of age worldwide. Both children and the elderly are at a higher risk for pneumonia complications. Countries in the Middle East and Africa have a higher mortality rate among children with pneumonia.
Epidemiology
Percentage of adults aged 65 and over who had ever received a pneumococcal vaccination: United States, 1997–2012 Graph obtained from CDC [1]
About 3.5 million deaths yearly have been attributed to lower respiratory tract infection. It is the third most common overall cause of death and the leading cause of death from infectious diseases.[2]
Pneumonia is one of the leading causes of death in the world and ninth leading cause in the United States. In 2001, 50,000 deaths were due to both pneumonia and influenza.
As many as 400,000 hospitalizations from pneumococcal pneumonia are estimated to occur annually in the United States. Pneumococci account for about 30% of adult community-acquired pneumonia. [3]
In 2012, 59.9% of adults 65 years and over received a pneumococcal vaccination.[4]
The number of discharges for patient admitted with pneumonia in hospitals in the US was 1.1 million patients in 2010.[4]
The average length of stay for those patients was 5.2 days.[4]
An increasing rate of CAP is seen with age. 5.16 to 6.11 cases of pneumonia per 1000 persons is observed in the community for adults. A pronounced seasonal effect on the number of patients presenting to emergency department was also noted. During the winter months, there was up to a 50% increase in the number of cases compared with the summer months.[5]Streptococcus pneumoniae is the leading cause of pneumonia worldwide.[6]
Pneumonia and influenza are the eighth and seventh cause of death in the United states and Canada respectively.[7][8]
A death rate of more than 60000 persons was recorded in 2005 due to pneumonia in ages more than 15 years. A difference in mortality ratio is observed in different countries like in United States/Canada 7.3 percent, Latin America 13.3 percent, Europe 9.1 percent.[9]
Mortality
A higher mortality rate is seen in invasive diseases, nursing home patients and severe bacteremia.
More than 40 % mortality rate is seen in ICU admitted patients.
The number of deaths in the US in 2011 was 52,294. [4]
16.8 deaths per 100,000 population in the US was reported in 2011 due to pneumonia. [4]
The percentage of hospital inpatient deaths from pneumonia in the US 2006 was 3.4%. [10]
