Nu variant is highly contagious and Infectious
Nawr Amrywiol- mewn esboniad posibl o ledaeniad cyflym y rhai sy'n dod i'r amlwg “Ddim” amrywiad o'r firws SARS-CoV2, a new study has found this particular variant (B.1.1.529) has a much higher ability to infect and evade the immune response built through previous infections or vaccines.
In a study published in Nature journal, a team of researchers from India and other countries has found that the NU variant (or B.1.1.529 lineage) was eight times more likely to escape immunity gained through AstraZeneca or Pfizer vaccines compared to the original virus.
Hefyd, the NU variant was six times more likely to re-infect people who have recovered from Covid-19.
Yn ôl yr UCL yn ystod yr un wythnos, this new Covid variant accounted for more than 80% o achosion newydd yn yr Unol Daleithiau. Dywed arbenigwyr iechyd ei bod yn nodweddiadol i straen newydd o firws fod yn fwy heintus oherwydd ei fod yn aml yn dod yn llawer mwy effeithlon ac yn hawdd ei drosglwyddo.
Mewn cymunedau â chyfraddau brechu is, yn enwedig ardaloedd gwledig sydd â mynediad cyfyngedig i ofal, the Nu variant could be even more damaging. Mae hyn eisoes yn cael ei weld ledled y byd mewn gwledydd tlotach lle nad yw'r brechlyn COVID-19 mor hygyrch. Dywed arbenigwyr iechyd y gellid teimlo'r effaith am ddegawdau i ddod.
Mae'r prif straen Covid-19 wedi rhoi'r ffocws yn ôl ar atal
1. Nu is more contagious than the other virus strains.
2. Mae pobl heb eu brechu mewn perygl.
3. Nu could lead to ‘hyperlocal outbreaks.’
4. There is still more to learn about Nu Variant.
5. Vaccination is the best protection against Nu Variant.
What do we know so far about this new Covid variant?
Of the 59 laboratory-confirmed cases of the new variant, three were in Botswana, two were in Hong Kong among people who had travelled from South Africa, and the rest were confirmed in South Africa.
Of course, it is not necessarily time to panic. We simply do not know enough yet about the virulence and transmissibility of this strain. And mutations can work in either direction. But it is further evidence that we cannot assume with Covid that it will naturally evolve to become less potent or simply burn out
