Patient's question:
Going home from school, my mom took me to the hospital to see my grandfather. It turned out that my grandfather had been feeling unwell for the past few days and had difficulty breathing. Later, my mom took him to the hospital for a thorough examination, where it was discovered that he had pneumonia. Fortunately, it was detected in time, and the condition was not yet severe.Regarding assistance: I would like to ask you a few times about the causes of pneumonia in the elderly.
Doctor's answer:
1. Gram-negative bacilli are common; in the 1950s, Streptococcus pneumoniae was the main pathogen causing pneumonia (90%). However, with the introduction of penicillin and some synthetic penicillins, the incidence and severity of pneumonia caused by this bacterium have increased.2. The transmission of respiratory opportunistic pathogens has been gradually increasing.
3. Mixed infections are common, as elderly individuals often exhibit mixed infections caused by multiple different pathogens due to weakened immune function.
4. Resistant bacteria are continuously increasing.
