As Covid progresses and the vaccination percentage is not followed, there is a high risk of emergence and spread of new strains, which may be more transmissible. According to information from the State Department of Health (Sesau), the subtypes with the highest number of cases in Alagoas are currently BA.1 and BA.2, omicron subtypes (the only circulating species). Among these, BA.2 most often.
Also according to Sesau, the file stays alert and monitors cases, especially with the transition of sub-variables. The report asks the secretariat where disclosure has already been made. “All municipalities. The measures being adopted for containment are the same as those already adopted: vaccination, avoiding agglomeration, respecting respiratory etiquette,” Sisao reported, regarding the BA2 strain, one of the omicron subvariants. Without going into details, Sisao told the report that “no detection has been disclosed.” any variable of interest, and that the subtypes circulating in the state are BA.1 and BA.2 and were detected in all municipalities in the Alagoas”.
The information is due to the fact that the omicron subvariants do not cause severe disease, at least not yet, so they are not considered ‘of benefit’. “So far the dominant variant is the omicron which contains five sub variants, which can escape from the patients’ immune system. The sub variants still do not cause a serious case of the disease,” highlights infectious disease specialist Rene Oliveira.
In the first half of this month, the Fiocruz Genomic Network released new data on the strains and variants of the coronavirus in Brazil. The report refers to the period from May 20 to June 2 and highlights the replacement of the BA1 strain by the BA2 strain of the micron variant and the increase in the detection of other strains with greater transmission potential. So far, vaccination coverage has been necessary to stem the increase in hospitalizations and severe cases, but the disease record continues to grow. The World Health Organization (WHO) has identified ten types of coronavirus, classified into four categories. Currently, mainly variables of concern are traded: microns and deltas.
Who is the
In November last year, the World Health Organization, in discussions with its network of experts, reported the identification of a new SARS-CoV-2 VOC, named Micron (B.1.1.529). Micron was first identified on 11/24/2021 in South Africa, in many provinces, and so far it has been reported in more than 170 countries.
The variant presents a series of mutations, some of which are alarming and require constant monitoring in countries. In Brazil, the first cases were confirmed on 12/1/2021. Thus, the WHO is currently considering alpha, beta, gamma, delta and micron VOC variants. Due to the significant reduction in the circulation of Alpha, Beta, Gamma and Delta VOCs, the WHO classified it as “previously circulating”, and the VOC micron and its sublines as “currently circulating”, as a result of relevant epidemiological trends.
