Pneumonia Facts Pneumonia is inflammation of the lungs caused by fungi, bacteria, or viruses. Symptoms and signs include cough, fever, shortness of breath, and chills. Antibiotics treat pneumonia, and the choice of the antibiotic depends upon the cause of the infection.
How it spreads. Rubella is caused by a type of virus called a togavirus. It is spread in a similar way to a cold or flu, through droplets of moisture from the nose or throat of someone who is infected. These droplets are released into the air when someone coughs, sneezes or talks.
What causes Shigellosis? Causes: Shigellosis: Shigella bacterial infection of the digestive tract. The disease is caused when virulent Shigella organisms attach to, and penetrate, epithelial cells of the intestinal mucosa. After invasion, they multiply intracellularly, and spread to contiguous epitheleal cells resulting in tissue destruction.
