What are pheumonies?

Answer 1

Pneumonias are inflammatory conditions of the lungs, primarily caused by infections from bacteria, viruses, fungi, or parasites. They result in the alveoli (air sacs) filling with fluid or pus, leading to symptoms such as cough, fever, difficulty breathing, and chest pain. Pneumonia can vary in severity, from mild cases that resolve at home to severe forms requiring hospitalization. Vaccines and antibiotics are often used for prevention and treatment, depending on the causative agent.
