2The Causes of Pneumonia
Generally speaking, pneumonia results from bacteria, viruses, and fungi. Identifying the causes of pneumonia helps doctors find out proper treatments for patients. Let’s start with bacterial pneumonia. Bacteria like streptococcus pneumonia (pneumococcus), mycoplasma pneumonia, chlamydophila pneumonia, and legionella pneumophila can cause bacterial pneumonia. Pneumococcus is the most seen type, and the other three germs are less common. Infected by those uncommon germs, people start to have atypical symptoms such as chills, fever, cough, chest pains, sore throats, etc. Compared to bacterial pneumonia, viral pneumonia often lasts a shorter period, and possible triggers include influenza viruses, respiratory syncytial virus (RSV), adenoviruses, and varicella-zoster virus (chickenpox). People with chronic health problems are more susceptible to fungi pneumonia. It is an infection complication caused by pneumocystis jirovecii, coccidioidomycosis, histoplasmosis, and cryptococcus.
