| Age of the sampled population |
The highest proportion of CDS users were those of 20−29 years (44.02%) and 30−39 years (26.96%). The predominant age groups were, in descending order, those of 10−19 years (18.65%), 20−29 years (17.54%), 0−9 years (16.65%), and 40–49-years (13.29%). Children under 10 years were not considered in this study. |
| The predominant CDS groups are adults with a smartphone and internet connection. The elderly population is less likely to have access to and master the mobile technology deployed in the field; the analysis was directed to risk cases younger than 65 years. |
| Availability of technological resources |
The CDS app was available for Android OS only; 68.3% of Mexico’s population has access to a smartphone, with 82.5% Android OS users, and 17.1% iOS users; the rest use Samsung, Windows, and PlayStation devices. |
| Availability of PCR COVID-19 tests |
Asymptomatic individuals infected with SARS-CoV-2 are not eligible for COVID-19 testing due to the limited number of tests available and therefore are not considered in the SSSLP data. |
