Abstract

The disease caused by (SARS-CoV-2), had a devastating effect on the world population. The study aims to analyze the number of positive tests compared to periods other than the Covid-19 correspondent pandemic to the periods of VOCs declared by the WHO. Using observational analytical methodology, through reports from a laboratory of the private health network located in the interior of São Paulo, from December/2020 to March/2022 with the data organized and statistically analyzed, the percentage of positivity of the tests was evaluated of covid with the periods of the VOC's. According to data from Fiocruz, from December 2020 to July 2021 in the state of São Paulo, there was a predominance of the gamma line (P1 R1). In this period, 12,982 exams were performed with an average positivity of 21.66%. In the period of prevalence of the delta lineage, there were a total of 3803 exams with an average positivity of 8.72%. In view of the emergence of the new Omicron variant, a total of 9107 tests were carried out from December 2021 to March 2022. The average positivity of the tests, 26.51%, however in January the record was recorded 46.67% of positive tests out of a total of 4905 tests.

Vaccination significantly reflected in the progress of VOC's. However, as described in the literature and in line with national perception, there was a significant increase in the number of cases and positivity in the Omicron sline, peaking in January 2022. Although the Covid-19 is in decline, attention to thesution of new variants is still necessary and of utmost importance.
