 Brazil patients 'test positive for TWO coronavirus variants at the same time' in world-first Covid double infection

Two patients in Brazil have tested positive for more than one strain of coronavirus at the same time in what is believed to be the world's first double Covid infection. Researchers at Feevale University made the discovery after swabbing 90 infected people in Rio Grande do Sul, southern Brazil. One of the patients tested positive for two Brazilian strains which evolved separately in different states, known as P.1 and P.2. P.1 has caused international alarm because it appears to be somewhat resistant to vaccines, which has led to Britain banning all travel from South America. Another patient tested positive for P.2 and the B.1.91 strain, which first appeared in Sweden, at the same time, according to the study, which has not yet been published in a scientific journal or scrutinised by other scientists. Fernando Spilki, the lead researcher on the study, said he feared the co-infections would 'generate combinations and generate new variants even more quickly'. Dr John McCauley, director of the Worldwide Influenza Centre at the Francis Crick Institute in London, told MailOnline it was possible for someone to get infected by two strains at the same time, which can happen with the flu. He warned that, while unlikely, it was also biologically possible the two strains could interfere with one another and swap genetic code. 'Getting one strain up a nostril and another up another nostril doesn't matter...but (the risk is) if they get to the back of the throat and then go into the same cell - then there's an opportunity for this to happen.' Another senior scientist, who asked to remain anonymous, said it was possible the Brazilian scientists had contaminated their samples during sequencing, leading to incorrect results. Brazil is in the middle of a devastating second wave of Covid, with more than 1,000 deaths a day, and has the second highest fatality toll worldwide. At least two variants have spawned there, which experts believe is due to such a high level of sustained transmission, and multiple others are in circulation. Dr Julian Tang, a professor in respiratory sciences at the University of Leicester, said it was 'not uncommon' for two strains of a virus to infect the same person. 'It is perfectly possible for a child attending a primary school to get infected with one variant of Covid-19, and an older sibling to attend secondary school and get infected with a different Covid-19 variant - and for both children to bring their viruses home to infect each other - and their parents with both variants,' he told MailOnline. Professor Lawrence Young, a virologist at the University of Warwick, said it was unlikely that two strains of Covid-19 could infect a cell at the same time. 'If one virus gets in it takes over that cell, and it's difficult for another to get in,' he told MailOnline. He added changes in the virus were being driven by random mutations: 'It does mutate at a very very low rate and a lot of (its mutations are) in response to the low pressure that we put on it.' He said it was through this mechanism that changes in the virus were occurring and new strains were evolving, and there was no proof that variants had emerged after swapping genes between different viruses.

 That is scary!

Thanks, Jaio!  You controlled the virus really well; on a par with your protection of the rainforest.

I posted a while ago about fuel infection by two different mutations ,

My post was about India

New Double variant,found in India.....

https://www.abc.net.au/news/2021-03-25/india-new-coronavirus-mutation-found/100027226

Well it's a little different,not sure what it means.....

Maybe we up s..t creek.....

Take care all 😷😉

Ok, but......is this in places that do not have access to the vaccine as readily as some others?  Or is this something we anticipate seeing everywhere no matter how many vaccinated?  I keep seeing stories of vaccinated people getting re-infected and even dying so I am really concerned.  I do not know how to gage my concern though because of so many different conclusions right now in society!

H7N9 + H9N2 makes H9N9 virus

This virus causes inapparent clinical disease in chickens, but zoonotic transmission results in severe and fatal disease in humans. We evaluated the consequences of reassortment between the H7N9 and the contemporary H9N2 viruses of G1 lineage that are enzootic in poultry across the Indian sub-continent and the Middle East. Co-infection of chickens with these viruses resulted in emergence of novel reassortant H9N9 viruses carrying genes derived from both H9N2 and H7N9 viruses. These reassortant H9N9 viruses showed significantly increased replication fitness, enhanced pathogenicity in chicken embryos and the potential to transmit via contact among ferrets. Our study highlights that the co-circulation of H7N9 and H9N2 viruses could represent a threat for the generation of novel reassortant viruses with greater virulence in poultry and an increased zoonotic potential.
