What are risk factors for pneumonia?

There are a number of factors that increase the risk of developing pneumonia. These include

  • a weakened immune system, either due to disease such as HIV/AIDS or cancer, or to medications that suppress immune function;
  • infants and children 2 years of age or younger;
  • age 65 and older;
  • having a chronic disease such as cystic fibrosis, COPD, sickle cell anemia, asthma, heart disease, or diabetes;
  • swallowing or coughing problems, as may occur following stroke or other brain injury;
  • being a patient in an intensive-care unit of a hospital, particularly if on ventilator support;
  • malnutrition; and
  • cigarette smoking.

What is the incubation period for pneumonia?

The incubation period for pneumonia depends on the type of organism causing the disease, as well as characteristics of the patient, such as his or her age and overall health status. Most cases of pneumonia 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. The symptoms of pneumonia can occur from a few days to a week following the flu-like symptoms.
