The mortality rate in our study (1.2%) was low in comparison with other studies. This may be due to the fact that our patients were not all admitted to the ICU, 5,14 and did not all have pneumonia at hospital admission. 15 Even so, the mortality rate was clearly lower than that found in the USA at the beginning of the pandemic (7%) 4 or the 4.9% reported in Canada. 16 Likewise, the rate of ICU admission (9.7%) was lower than that found in the USA (25%) 4 and Canada (16%), 16 although it was similar to the 8% reported in New Zealand Maoris. 17 Some form of selection bias cannot be completely ruled out as our study patients had to be interviewed to collect data on the use of medications before admission and other risk factors related to disease severity. In a study carried out in Catalonia (north-east Spain), of 773 cases hospitalized, 37.9% were admitted to the ICU. 18 In contrast, in Andalusia (southern Spain), 28 out of 311 hospitalized cases (9%) were admitted to an ICU. 19 In another Spanish study of patients admitted to the ICU, the mortality rate was 22%. 20 Taken together, these data suggest that patients who died shortly after admission were not picked up by our study.
