Argentina: mandatory Covid vaccination law in parliament

A bill has been introduced in the Argentine Chamber of Deputies to mandate vaccination against Covid-19 for all residents of the country. Since it falls within the framework of Immunization Law 27.491, passed in 2018, it can even be “coercively” applied; authorities can demand a fine or jeopardize the implementation of basic procedures such as the renewal of identity cards, passports or driver’s licences, to which every citizen and resident is entitled.

Preprint: MU B.1.621 the most resistant variant to convalescent and vaccinated sera to date

Here, we demonstrate that the Mu variant is highly resistant to sera from COVID-19 convalescents and BNT162b2-vaccinated individuals. Direct comparison of different SARS-CoV-2 spike proteins revealed that Mu spike is more resistant to serum-mediated neutralization than all other currently recognized variants of interest (VOI) and concern (VOC). This includes the Beta variant (B.1.351) that has been suggested to represent the most resistant variant to convalescent and vaccinated sera to date.

Preprint: C.37 Lambda variant exhibits higher infectivity and immune resistance

“In this study, we demonstrated that three mutations, the RSYLTPGD246-253N, L452Q and F490S mutations, respectively confer resistance to the vaccine-induced antiviral immunity. Additionally, the T76I and L452Q mutations contribute to enhanced viral infectivity. Our data suggest that there are at least two virological features on the Lambda variant: increasing viral infectivity (by the T76I and L452Q mutations) and exhibiting resistance to antiviral immunity (by the RSYLTPGD246-253N, L452Q and F490S mutations).”

Alzheimers Association: COVID-19 associated with acceleration of Alzheimer’s symptoms

Key results:  Biological markers of brain injury, neuroinflammation and Alzheimer’s correlate strongly with the presence of neurological symptoms in COVID-19 patients.  Individuals experiencing cognitive decline post-COVID-19 infection were more likely to have low blood oxygen following brief physical exertion as well as poor overall physical condition.

“These new data point to disturbing trends showing COVID-19 infections leading to lasting cognitive impairment and even Alzheimer’s symptoms,” said Heather M. Snyder, Ph.D., Alzheimer’s Association vice president of medical and scientific relations. “With more than 190 million cases and nearly 4 million deaths worldwide, COVID-19 has devastated the entire world. It is imperative that we continue to study what this virus is doing to our bodies and brains. The Alzheimer’s Association and its partners are leading, but more research is needed.”

Preprint: Infectivity and immune escape of the new coronavirus variant of interest C.37 Lambda

“We also observed that the spike protein of the Lambda variant presented increased infectivity when compared with the spike protein of the Alpha and Gamma variants, both of them with reported increased infectivity and transmissibility. Together, our data show for the first time that mutations present in the spike protein of the Lambda variant confer escape to neutralizing antibodies and increased infectivity.”

“The evidence presented here reinforces the idea that massive vaccination campaigns in countries with high SARS-CoV-2 circulation rates must be accompanied by strict genomic surveillance aimed to rapidly identify new viral isolates carrying spike mutations as well as studies aimed to analyze the impact of these mutations in immune escape and vaccines breakthrough.”

Preprint: The emergence of Sars-CoV-2 coronavirus variant Lambda C.37 in South America

We report the emergence of a novel lineage of SARS-CoV-2 in South America, termed C.37. It presents seven nonsynonymous mutations in the Spike gene (Δ247-253, G75V, T76I, L452Q, F490S, T859N) and a deletion in the ORF1a gene (Δ3675-3677) also found in variants of concern (VOCs) Alpha, Beta, and Gamma. Initially reported in Lima, Peru, in late December 2020, it now accounts for 97% of Peruvian public genomes in April 2021. It is expanding in Chile and Argentina, and there is evidence of onward transmission in Colombia, Ecuador, Mexico, the USA, Germany, and Israel. On June 15, 2021, the World Health Organization designated C.37 as Variant of Interest (VOI) Lambda.

Argentina: coronavirus death toll hits 95,000 as Delta cases fly in

The Argentine Health Ministry confirmed Friday that two new Covid-19 cases with the Delta variant had been detected by migration officials, as Argentina’s death toll reached 95,000.  The two Delta cases, according to the government, were detected in two adult residents who recently returned to the country from the United States and Venezuela. Both had previously tested negative for Covid-19 before boarding a plane to Argentina and their tests carried out after landing at Ezeiza international airport also came back clean. However, both began showing symptoms a few days after arrival. New tests confirmed they were positive for the virus and both individuals are now in isolation, said the Health Ministry.

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

Argentina judge orders chlorine dioxide be given to #coronavirus patient

“An Argentine judge has compelled a private clinic to administer chlorine dioxide, used as a powerful disinfectant, to a coronavirus patient in a case medical doctors have labelled “a scandal.”

The stepson of the patient brought a legal bid last Thursday, the day after his mother died of Covid-19, for the compound to be given to her critically-ill husband.

Federal Judge Javier Pico Terrero granted the request the same day and ordered the Otamendi y Miroli clinic in Buenos Aires to administer the substance, prescribed by the patient’s doctor, Dante Converti.”

Chinese expert call for #COVID circuit-breaker amid cases related to frozen food imports

China has seen a continuous rise in cases of contaminated frozen food from overseas and patients of coronavirus infections related to the import industry, which prompted Chinese health experts to suggest an expanded testing scale and a circuit-breaker mechanism for imports like that for international flights.

There have also been continued reports of imported frozen food testing positive. South China’s Guangdong Province reported two new cases of imported food testing positive for coronavirus on Saturday. One is imported from Argentina, and the other is from Russia.

Europe is main source of #SarsCov2. Travel restrictions in #UK and Europe “too few” and “too late”

It is not China but Europe the area of ​​the world identified as the main source of spread of Sars-Cov-2, the virus that causes Covid-19.

To say this is a study on the viral genome that was carried out by the Universities of Huddersfield, in the United Kingdom, and of the Minho, in Portugal, and which was published in the scientific journal Microorganisms. Work focused on the 27,000 Sars-Cov-2 viral genomes identified around the world since the start of the pandemic.

Thanks to this analysis, the researchers noted that travel restrictions in Great Britain and the rest of Europe seem to have been “too few” and made “too late” and that the actual spread to America and other parts of the planet are occurred largely through Europe and not from China, where the virus originated.

“It seems likely – the scholars explain – that the travel bans established throughout the world in the second half of March have helped to decrease the number of intercontinental trade, particularly from mainland China, but were less effective between Europe and North America where trade in both directions was visible until April, long after the bans were imposed. ”
