Sumary of This Devastating Covid-19 Outbreak In Brazil Is A Warning To The Rest Of The World:
- Genomic sequencing, conducted retroactively on samples of viral RNA from Manaus residents dating back to late December, revealed that 42 percent belonged to a previously unidentified lineage of SARS-CoV-2.
- Along with an orf1b deletion, P.1 has these mutations in common with B.1.1.7, the so-called UK variant, and 501.V2, the so-called South African variant.
- This new variant, now known as P.1, is the very same that Japanese travelers contracted and brought back to Tokyo earlier this month.
- If P.1 is now the dominant SARS-CoV-2 variant circulating in Manaus, that suggests it has an evolutionary edge that runs counter to the city’s immune defenses, meaning reinfections like the youthful woman’s will become more commonplace if they haven’t already.
