New Official Information: How to Calculate the Infection Rate and Why There Are Differences from Daily New Case Reports – Coronavirus

The COVID-19 incidence rate at 14 days is not calculated on the basis of daily new confirmed cases in public statistics, but on the basis of the date that samples taken from patients are entered into the system. The clarifications were made on Friday by the Strategic Communication Group, after there were debates in the public space about the inaccuracy of the data in the contagion rate report.

Thus, according to the cited source, the number of new positive cases sent in the daily bulletin, at 1:00 p.m., represents the total of positive results for people confirmed for the first time and reported up to the date the information was sent.

Unlike these data sets, in the methodology for calculating the incidence rate reported in the last 14 days, The Public Health Directorates take into account the number of new positive cases, depending on the date they were uploaded to the computer system.

“Therefore, the cumulative incidence of spread during the last 14 days is calculated based on when the sample of the person in question is entered into the system, and not based on when the test center reports it. for its centralization and then publicly communicated, an inherent gap from one day to the next. The evidence of the positively detected cases is managed in the computer application, in which the times in which the samples are processed in the test centers and, subsequently, positive results are found ”, is shown in the Strategic Communication Group.
