Nu variant is highly contagious and Infectious
Sasa Lahaja- kwa maelezo yanayowezekana ya kuenea kwa haraka kwa wanaojitokeza “Sivyo” lahaja ya virusi vya SARS-CoV2, utafiti mpya umepata lahaja hii (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.
Pia, the NU variant was six times more likely to re-infect people who have recovered from Covid-19.
Kulingana na UCL wakati wa wiki hiyo hiyo, this new Covid variant accounted for more than 80% ya kesi mpya huko Merika. Wataalam wa afya wanasema ni kawaida kwa aina mpya ya virusi kuambukiza zaidi kwa sababu mara nyingi inakuwa yenye ufanisi zaidi na inayoambukizwa kwa urahisi.
Katika jamii zilizo na viwango vya chini vya chanjo, haswa maeneo ya vijijini na upatikanaji mdogo wa huduma, the Nu variant could be even more damaging. Hii tayari inaonekana ulimwenguni kote katika nchi masikini ambapo chanjo ya COVID-19 haipatikani. Wataalam wa afya wanasema athari inaweza kuhisi kwa miongo kadhaa ijayo.
Aina kubwa ya COVID-19 imerudisha nyuma uzuiaji
1. Nu is more contagious than the other virus strains.
2. Watu ambao hawajachanjwa wako katika hatari.
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.
Kwa kweli, 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. Lakini ni ushahidi zaidi kwamba hatuwezi kudhani na Covid kwamba itabadilika kwa asili na kuwa na nguvu kidogo au kuchomwa moto.
