The pneumonia is a respiratory disease that causes a lung infection. It can be caused by various agents like viruses, bacteria, fungi, and affects many people during the year. In most cases, pneumonia in adults is produced by bacteria.
The most common type of bacteria that causes pneumonia is pneumococcus (Streptococcus pneumoniae). In addition, there are different types depending on where it occurs. Thus, for example, pneumonia may be intrahospital, the condition occurring when the patient has been hospitalized or in medical centers. In this case they are given out of hospitals or outside medical centers.
