   Pneumonia can develop when your immune system attacks an infection in the small sacs of your lung (alveoli). This causes your lungs to swell and leak fluids. Many bacteria, viruses and fungi can cause the infections that lead to pneumonia. Bacteria are the most common cause in adults and viruses are the most common cause in school-aged children. Co...

   Pneumonia itself isn’t actually contagious, but the bacteria and viruses that cause it are. For instance, the flu is contagious and can lead to pneumonia, but most people who get the flu won’t get pneumonia. The bacteria that most commonly causes pneumonia, Streptococcus pneumoniae,can be spread from person to person by touching infected surfaces o...

   What is pneumonia in the lungs?

   • Within the host, pneumonia is by definition within the lungs, but it is a complex disease that involves diverse physiological systems working together. Although pneumonia is an acute event, it is prompted by preexisting chronic conditions, and it has long-term consequences.

   Do we understand the physiological underpinnings of pneumonia susceptibility?

   • Our understanding of the physiological underpinnings of pneumonia susceptibility are too rudimentary and incomplete to guide useful countermeasures that will preserve or restore defects in resistance and resilience that develop due to comorbidities or exposures.
