Nu variant is highly contagious
Sasa Lahaja – in a possible explanation of the rapid spread of the Delta variant of the SARS-CoV2 virus, a new study has found this particular variant 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 Delta variant (or B.1.617.2 lineage) was eight times more likely to escape immunity gained through AstraZeneca or Pfizer vaccines compared to the original virus. Also, the Delta variant was six times more likely to re-infect people who have recovered from Covid-19.
Kulingana na UCL wakati wa wiki hiyo hiyo, the Mu 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.
