Pneumonia remains a common yet manageable respiratory illness, with key symptoms including chest pain, cough, and fever. Recognizing early signs is vital, especially for vulnerable groups. Causes include bacteria, viruses, and fungi, with severity varying based on individual health. Proper diagnosis and prompt treatment are essential to prevent complications.

Pneumonia Overview: Causes and Typical Symptoms

Pneumonia, once a serious threat before antibiotics, is now often treatable thanks to medical advances. Yet, hospital-acquired infections are increasingly resistant to antibiotics, posing new challenges for healthcare providers.

Initial symptoms of pneumonia can resemble a cold or flu but tend to persist longer. Common indicators include chest discomfort during breathing or coughing, fatigue, and confusion, especially in seniors over 65. Other signs encompass fever, sweating, chills, shivering, and coughing with mucus. Symptoms may also include shortness of breath, nausea, or diarrhea. Infants may show signs of restlessness, exhaustion, fever, and difficulty breathing. Early diagnosis and treatment are critical, particularly for vulnerable groups such as the elderly, young children, and immunocompromised individuals.

Causes of pneumonia include bacterial pathogens like Streptococcus pneumoniae, fungi, and viruses responsible for cold and flu. Bacterial pneumonia often impacts a single lung lobe, known as lobular pneumonia. Milder variants, such as walking pneumonia caused by Mycoplasma, are common. Fungal pneumonia typically affects those with weakened immune systems. Viral pneumonia mostly occurs in young children and can become severe if untreated. While not always life-threatening, pneumonia can worsen without prompt care, especially in at-risk populations.
