Flu virus is a primitive non-living sub-microscopic infectious organism that causes respiratory disease in mammals. Pneumonia is a clinical disease - an infection of the lungs that can be caused by damage to the lung tissue by environmental contaminants such as smoke or other chemical irritants and a number of different micro-organisms. Some forms are caused by viruses, for example in viral pneumonia, but most commonly pneumonia is caused by bacteria that are living microscopic organisms that also can produce disease in mammals. Fungi can also cause pneumonia. Both the flu and pneumonia are diseases of the respiratory system, but are caused by different "germs" and/or pollutants. This means that it usually takes different drugs to treat the two kinds of infections, although symptoms can be very similar in humans.
