UNASSIGNED: Community-acquired @entity55 in adults is a common cause of morbidity and mortality particularly in the elderly and in @entity1 with comorbidities. Most episodes are of bacterial origin, @entity328 is the most frequently isolated pathogen. Epidemiological surveillance provides information about changes in microorganisms and their susceptibility. In recent years there has been an increase in cases caused by community-acquired meticillin resistant @entity794 and Legionella sp. The chest radiograph is essential as a diagnostic tool. CURB-65 score and pulse oximetry allow stratifying @entity1 into those who require outpatient care, general hospital room or admission to intensive care unit. Diagnostic studies and empirical antimicrobial therapy are also based on this stratification. The use of biomarkers such as @entity1904 or @entity1851 is not part of the initial evaluation because its use has not been shown to modify the initial approach. We recommend treatment with @entity115 for outpatients under 65 year old and without comorbidities, for @entity1 65 years or more or with comorbidities @entity115 -clavulanic/ @entity5899 , for @entity1 hospitalized in general ward @entity869 - @entity5899 with or without the addition of @entity4581 , and for @entity1 admitted to intensive care unit @entity869 - @entity5899 plus @entity4581 . Suggested treatment duration is 5 to 7 days for outpatients and 7 to 10 for those who are hospitalized. During the @entity683 season addition of @entity684 for hospitalized @entity1 and for those with comorbidities is suggested.
