Pneumonia: Preventing, Recognizing, and Treating Pneumonia Disease

Understanding pneumonia starts with recognizing the different types of the disease. The most common types are bacterial, viral, and fungal pneumonia, each caused by different pathogens and each requiring distinct treatment approaches. Bacterial pneumonia is typically caused by Streptococcus pneumoniae, which is the most common bacterial pathogen responsible for hospitalizations. Other bacteria, such as Haemophilus influenzae and Staphylococcus aureus, can also lead to pneumonia. Viral pneumonia, often caused by influenza viruses, respiratory syncytial virus (RSV), and coronaviruses, is another common form, and its severity can vary based on the viral strain and the individual’s overall health. Fungal pneumonia is less common and typically occurs in individuals with weakened immune systems, with fungi like Histoplasma, Coccidioides, and Cryptococcus causing infections.
