This is most common among individuals with a weak immune system. The majority of people who fit this description are infants and newborns as well as older adults who are sixty and older. Those who have been infected by a virus that induces immune deficiency such as HIV are also at risk of developing Viral Pneumonia. Patients who are receiving chemotherapy are also at risk.
In the U.S., approximately 2 million people of all ages are infected a year (conclusion after a study between 2001 and 2004). Of the 2 million people infected, 4% consisted of young children. In addition, Viral Pneumonia is the fourth leading cause of death for the elderly. Fortunately, the number of deaths per infected showed a declining trend following intensive studies.
