Demographic analysis
Of the 103 cases of COVID-19 analysed, 74 (71.8%) were of outpatients who never needed hospitalization, 12 (11.7%) were of patients who recovered but who at some point had more severe symptoms and needed hospitalization in the course of the disease, and 17 (16.5%) were of patients who needed hospitalization but died. Sixty-two were men (60.2%), and 41 were women (39.8%). The mean age was 44.4 years, ranging from 6 to 85. The population was divided into four age groups according to the Mexican Institute of Social Security’s health handbooks. Following this classification, the cases were distributed as follows: one patient was aged 0 to 9 years (0.9%), one aged 10 to 19 years (0.9%), 83 aged 20 to 59 years (80.6%), and 18 aged 60 years or older (17.5%). The samples analysed were from 18 Mexican states; 13 were from the northern region (12.6%), 80 the central region (77.7%), and 10 the southern region (9.7%) (Table 2).
Table 2 also shows that the percentages of hospitalizations and deaths were significantly higher in male patients than in female patients (both P<0.05) and that older age was also associated with a higher probability of death due to COVID-19, with the mean age in the group of outpatients being 41.6 years versus 55.2 years in the group of deaths (P<0.05).
