Introduction:

Community acquired pneumonia is a health problem that has not yet been resolved and in Guantanamo the influence of the seasons of the year on its frequency has not been clarified.

Objective:

To determine the morbidity and mortality due to severe pneumonia acquired in the community in said unit during 2018.

Method:

A retrospective study of the total number of patients admitted (N=85) for this cause was made. The variables studied were: age, sex, severity index, comorbidity, stay in the unit, need for mechanical ventilation, state at discharge. All related to the seasons.

Results:

The largest number of patients admitted during the winter (35.3%). There was no significant relationship between the season of the year and the sex variable (p<0.05), but with age, stay in the unit, comorbidity, risk of respiratory failure and need for treatment with mechanical ventilation (p<0.05).

Conclusions:

The morbidity of severe pneumonia acquired in the community showed a seasonal distribution, since in winter its frequency was higher, but it did not determine its lethality, which was more mediated by the comorbidity of the patient.
