Common Causes of Pneumonia A common cause of bacterial pneumonia is Streptococcus pneumoniae (pneumococcus). However, clinicians are not always able to find out which germ caused someone to get sick with pneumonia. Community-acquired pneumonia is when someone develops pneumonia in the community (not in a hospital).
How do you get bacterial pneumonia?
The most common way you catch pneumonia is to aspirate bacteria from the upper airway, usually the oral cavity. Other ways to catch pneumonia can be by breathing in infected air droplets from someone who has pneumonia. In some cases, the bacteria can be generated by an improperly cleaned air conditioner or Jacuzzi.
What are the two main causes of pneumonia?
The main types of pneumonia are:
- Bacterial pneumonia. This type is caused by various bacteria.
- Viral pneumonia. This type is caused by various viruses, including the flu (influenza), and is responsible for about one-third of all pneumonia cases.
- Mycoplasma pneumonia.
- Other pneumonias.
What is the most common cause of pneumonia in adults?
The most common cause of bacterial pneumonia in the U.S. is Streptococcus pneumoniae. This type of pneumonia can occur on its own or after you’ve had a cold or the flu. It may affect one part (lobe) of the lung, a condition called lobar pneumonia.
How can you avoid getting pneumonia?
You can help prevent pneumonia by doing the following:
- Get the flu vaccine each year. People can develop bacterial pneumonia after a case of the flu.
- Get the pneumococcal vaccine.
- Practice good hygiene.
- Don’t smoke.
- Practice a healthy lifestyle.
- Avoid sick people.
Who is most at risk of pneumonia?
Certain people are more likely to become ill with pneumonia: adults 65 years or older; children younger than 5 years old; people who have ongoing medical conditions (like asthma, diabetes or heart disease); and people who smoke cigarettes.
Can you catch pneumonia from someone who has it?
Pneumonia is contagious just like a cold or flu when it is caused by infectious microbes. However, pneumonia is not contagious when the cause is related to a type of poisoning like inhalation of chemical fumes.
What kind of pneumonia does Covid cause?
Acute Respiratory Distress Syndrome (ARDS) As COVID-19 pneumonia progresses, more of the air sacs become filled with fluid leaking from the tiny blood vessels in the lungs. Eventually, shortness of breath sets in, and can lead to acute respiratory distress syndrome (ARDS), a form of lung failure.
How dangerous is bacterial pneumonia?
In the study of nearly 5,000 patients, researchers found that patients diagnosed with bacterial pneumonia had a 60 percent greater risk of a heart attack, stroke, or death than patients who had been diagnosed with viral pneumonia.
What are the three major causes of pneumonia?
Bacterial pneumonia. The most common cause of bacterial pneumonia is Streptococcus pneumoniae.
Which Gram-negative bacteria can cause bacterial pneumonia?
Klebsiella [kleb−see−ell−uh] is a type of Gram-negative bacteria that can cause different types of healthcare-associated infections, including pneumonia, bloodstream infections, wound or surgical site infections, and meningitis.
