Senile pneumonia infection

Pathogens can be bacteria, viruses, fungi, mycoplasma, etc. Bacterial pneumonia is the most common, and pathogenic bacteria are Streptococcus pneumoniae. The elderly are the high-risk group of pneumonia due to low immunity. The symptoms of patients are mainly high fever, cough and cough. Bacterial pneumonia is generally not infectious. However, if pneumonia is caused by atypical pathogens such as viruses and mycoplasma, it is often infectious and normally transmitted by droplets.
