Preprint: Emergence and spread of a B.1.1.28-derived lineage with Q675H and Q677H Spike mutations in Uruguay

In a previous study we found a sublineage B.1.1.28+Q675H+Q677H with local transmission in Rocha, a Uruguayan department bordering Brazil. This clade probably arose by early November, 2020, and its introduction from other parts of Uruguay seemed like a reasonable hypothesis. To understand whether these sequences were part of a new emergent SARS-CoV-2 lineage broadly disseminated in Uruguay, herein we analyzed the genetic diversity of B.1.1.28 SARS-CoV-2 viruses circulating in different localities by the end of 2020 and first months of 2021.

The highest ever #coronavirus daily case rates recorded on Planet Earth – and it’s not India or Brazil

The highest ever daily country case figure for coronavirus on Planet Earth was recorded in The Seychelles in May 2021. The Seychelles daily case figure, adjusted for population, reached an astonishing 4,083 cases per million. 

What is also surprising is that many of the countries on the list with the highest daily case rates also have excellent vaccination rates (see below). The Seychelles, for example, has vaccinated more than 60% of its population.

The reasons behind some of the high daily case numbers are given in articles we have previously published and have linked to below.

 

Seychelles: a population of 100,000 that has 900 #coronavirus vaccine breakthrough cases

Maldives: 60% positivity rate in Greater Male – “High chance of new #coronavirus variant”

Uruguay: over 1,000 daily new confirmed COVID-19 cases per million people

Sweden’s daily #coronavirus case rate far higher than Brazil or India

Uruguay: over 1,000 daily new confirmed COVID-19 cases per million people

Uruguay registered Thursday out 4,412 new cases of coronavirus of on a total of 18,835 tests, reported the National Emergency System (Sinae). The positivity rate was 23.4%.  In addition, there were 79 deaths in the last 24 hours of patients with covid-19. This Thursday, the highest number of deaths from coronavirus was also registered.
