The WHO (World Health Organization) in its weekly report on COVID-19 released this Tuesday (21) reported that the delta version of the coronavirus is already prevalent “in most regions of the world”.
The organization also states that the strain identified in India in October 2020 represented 90% of all genetic sequences submitted to the GISAID global database, with the sample collection date between 15 June and 15 September.
In Brazil, data from the Fiocruz genomic network shows that the delta is already prevalent in Brazil, with 74.5% of all genomes sequenced in August. In the previous month, the spread was 25.4%.
Delta is classified as a VOC (anxiety type) by the WHO, specifically because it is much more permeable than other strains such as alpha, beta and gamma.
The variant has a greater potential to reduce the activity of neutralizing antibodies conferred by COVID-19 itself and by vaccination.
However, full vaccination is the best way to avoid serious illness, no matter the type.
