What are the causes of pneumonia in the elderly?

Answers

  1. Gram-negative bacterial infections are commonly present, especially in the 1950s when Streptococcus pneumoniae was the main pathogen (about 90%) for pneumonia. However, with the introduction of penicillin and some semi-synthetic penicillins, the incidence and severity of pneumonia caused by this strain have increased.
  2. Respiratory condition pathogen infections are gradually increasing.
  3. Mixed infections are common, as the elderly often suffer from mixed infections caused by multiple different pathogens due to their weakened immune function.
  4. Drug-resistant strains are continuously increasing.
