Death from smallpox ranged up to about 35%, with the more severe, hemorrhagic form nearly 100% fatal. Patients who survived smallpox infection nearly always had multiple areas of scarring where each pock had been.

Pneumonia is an infection of the lungs. Many different organisms can cause it, including bacteria, viruses, and fungi.Pneumonia is a common illness that affects millions of people each year in the United States.Bacterial pneumonias tend to be the ...

The most common mechanism by which the lung is inoculated with pathogenic organisms is through microaspiration of oropharyngeal contents, a process that occurs in otherwise healthy individuals during sleep ( Chapter 82 ). Colonization of the oral pharynx with pathogenic organisms, such as Streptococcus pneumoniae ( Chapter 303 ), can thereby lead to delivery of sufficient quantities of organisms to infect the lung.

Pneumonia is an infection of the lung, and can be caused by nearly any class of organism known to cause human infections. These include bacteria, viruses, fungi, and parasites.

Introduction Pneumonia has been recognized as a disease entity since remote times, with definitions of the condition traceable in ancient Greek, Roman, and Arabic writings. Definitive recognition of the etiologic role of microorganisms in pneumonia, and the identification of Streptococcus pneumoniae as the most common causative agent was only achieved roughly 120 years ago.
|
|
The actual incidence of pneumonia in ambulatory patients is difficult to estimate because the etiologic agent is rarely identified except in clinical trials, and CAP is not currently considered a reportable disease. Each year in the United States there are 2 to 3 million cases of CAP.
