When is pneumonia contagious?
Pneumonia is contagious when the causative pathogens (usually bacteria or viruses) are expelled by an infected person by coughing out infected droplets. These expelled droplets contain the bacteria or virus that causes the pneumonia. These droplets contaminate the mouth or breathing tract of another individual to eventually infect their lungs.
The approximate time when pneumonia becomes contagious varies with the type of infecting agent and may r ... ange from one to two days to weeks. In addition, some pneumonias are more highly contagious than others. For example, Mycobacterium and Mycoplasma organisms are highly contagious, but other types, including pneumococcal pneumonia, require optimal conditions to spread to another person and are weakly contagious.
What is the incubation period for pneumonia?
The incubation period for pneumonia depends on the type of pathogen causing the disease, the person's age, and his or her overall health. In general, most pneumonias begin with symptoms similar to those of a cold or the flu that last longer than the flu (about seven to 10 days) and become more severe.
