Klebsiella pneumoniae is a bacterium that normally lives inside human intestines, where it doesn't cause disease.
But if K. pneumoniae gets into other areas of the body, it can lead to a range of illnesses, including pneumonia, bloodstream infections, meningitis, and urinary tract infections.
Causes and Risk Factors of a Klebsiella Pneumoniae Infection
K. pneumoniae infections are typically "nosocomial" infections, which means they're contracted in a hospital or healthcare setting.
Healthy people usually don't have to worry about getting K. pneumoniae infections, according to the Centers for Disease Control and Prevention (CDC).
The bacteria are not airborne, so you can't contract a K. pneumoniae infection by breathing the same air as an infected person.
Instead, K. pneumoniae is spread through direct person-to-person contact, such as when someone with contaminated hands touches a wound.
Long courses of antibiotics can also increase a person's risk of getting a klebsiella infection.
Duration of a Klebsiella Pneumoniae Infection
The duration of treatment for klebsiella infection varies from a few weeks to several months, depending on the individual, location of infection, and how early the infection is caught.
Prevention of a Klebsiella Pneumoniae Infection
To prevent the spread of germs, patients should also wash their hands frequently, including:
- Before touching their eyes, nose, or mouth
- Before preparing or eating food
- After using the bathroom
- After coughing, sneezing, or blowing their nose
- Before and after changing wound dressings and bandages
- After touching surfaces in the hospital like bedside tables, bed rails, doorknobs, remote controls, and the phone
