The delta variant is responsible for 99.79% of COVID-19 cases in the state of Rio de Janeiro, says the third genomic surveillance newsletter COVID-19, which was released this Friday (1st). This type of identification was done in all municipalities in nine regions of the state.
According to the newsletter, out of 468 samples with a collection date in September, only one was identified as Gamma and four as variants B1.1.28 and B1.1.33, which were classified as Alert, Interest or Concern variants. not classified as

The folder emphasizes that sequencing the new coronavirus is not a routine or diagnostic test. This is done as part of genomic surveillance to identify changes caused by the SARS-CoV-2 virus in the state and support health policies.
