The ômicron variant already represents 92.6% of positive tests for the detection of Covid in Brazil, indicates a survey carried out by laboratories in the country released this Thursday (6). In the previous version of the same study, released on December 29, the strain appeared with a predominance of 31.7%.
The new work, carried out from December 26 to January 1, was coordinated by the ITpS (All for Health Institute) in partnership with the laboratories Dasa and DB Molecular.
The investigation involved more than 2,400 special RT-PCR tests performed at the two laboratory networks. It was thus found that 337 were positive for Sars-CoV-2, the virus that causes Covid-19. Among these, 312 (92.6%) were from infections caused by the new variant.
According to ITpS, within the days of the survey, the strain was found in 80 municipalities in eight Brazilian states: Bahia, Goiás, Minas Gerais, Mato Grosso, Rio de Janeiro, Santa Catarina, São Paulo and Tocantins, in addition to the Federal District.
The omicron was initially sequenced in South Africa in November of this year. Preliminary data indicate that it is more transmissible than other variants, such as delta, although it does not develop serious conditions in many of those infected.
This Thursday (6), Tedros Adhanom Ghebreyesus, director-general of the WHO (World Health Organization), said that although “the omicron appears to be less severe than the delta, this does not mean that it should be classified as mild. as in previous variants, the omnitron is causing hospitalizations and deaths”.
A bulletin from the organization also released on Thursday indicated a 100% increase in Covid cases between December 27, 2021 and January 2, 2022 compared to the previous week. Most of them were registered in the United States, Argentina and Canada.
In the case of Brazil, data from this Tuesday (4) from the press vehicle consortium already show that the moving average of cases has now reached 9,874, a growth of 223% compared to data from two weeks ago.
