Infection of the lungs with bacteria, virus, parasites or fungi is referred to as pneumonia. In pneumonia either inflammation or fluid accumulation occurs in the alveoli (the microscopic sacs present in the lungs where oxygen is entered into the blood). Although pneumonia can affect individual of any age group; however, it is likely to be more dangerous in babies, elderly and individuals who suffer from other diseases or have a suppressed immune system. Pneumonia is primarily caused due to an infection with either a bacterium or a virus. Individuals who are at higher risk for developing pneumonia include those who smoke, abuse alcohol, suffer from other medical problems such as COPD, asthma, emphysema or HIV/AIDS, are younger than 1 year or older than 65 years, have an impaired immunity, take drugs to relieve GERD, or are malnourished. Majority of the patients start with symptoms of cold and flu and then develop symptoms of pneumonia (high temperature, chills and cough with rusty or green sputum).
