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.
In one in 6,000 cases it can lead to inflammation of the brain; in one in 3,000 cases it can affect blood clotting. The incubation period for rubella is 14 to 21 days, with most people developing a rash between 14 and 17 days after exposure.
