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).
