Github: AY.3.1 – a new sub-lineage of AY.3 concentrated in Mississippi, USA

AY.3 is the main variant being sequenced weekly in Mississippi (>70% of all recent sequences), most falling within this sub-lineage of AY.3 that is distinguished by the mutations described below (>60% of all recent sequences). For example, of 91 Pangolin-typeable sequences generated on 13 July 2021 by Dr. Robinson’s team, from broad sampling across Mississippi, 68 are AY.3 and 13 are unclassified B.1.617.2. Of those 81 Delta sequences, 60 are this new sub-lineage (those sequences are not yet in GISAID and are thus not included in the counts above for the USA or MS). Thus, there is clear epidemiological relevance of this sub-lineage in a region of the USA.

USA: AY.3 genomes increasing faster than Delta B.1.617.2

A long and detailed Twitter thread by Vinod Scaria on the rise of the AY.3 Delta plus variant in the USA which seems to be outcompeting Delta B.1.672 in some states. Outbreak.info is showing that AY.3 genomes are found in 37% of recent sequences.

USA: At least 125,000 vaccine breakthrough infections, 1,400 dead

At least 125,000 fully vaccinated Americans have tested positive for Covid and 1,400 of those have died, according to data collected by NBC News.  The total number of breakthrough cases is likely higher than 125,683, since nine states, including Pennsylvania and Missouri, did not provide any information, while 11, like Florida, did not provide death and hospitalization totals. Four states gave death and hospitalization numbers, but not the full tally of cases.

Mississippi: 78 cases of vaccine breakthrough reported

The Mississippi State Department of Health is reporting 78 breakthrough cases of COVID-19. Of those 78 breakthrough cases, one individual died of COVID-19.

“That’s one of the things that we’re following, is to look at who is being impacted with breakthrough COVID after they’ve been fully vaccinated,” said state epidemiologist Dr. Paul Byers.

State health leaders said there are 635,000 fully vaccinated Mississippians and the number of breakthrough cases is comparatively low. They said that’s proof the vaccines are working.
