How Contagious Is Pneumonia
In general, some types of pneumonia that are caused due to bacterial or viral infections are highly contagious. The infection spreads rapidly when the person who has it sneezes or coughs openly. They contain infectious germs in their respiratory tract. The germs residing in their nose and throat can get passed on to another person via air, because illnesses like flu, cold, and pneumonia are air-borne diseases.
