Ang SARS-CoV-2 baryants na nagsasanhi ng COVID-19 sa mundo sa kasalukuyan
Positive, negative, and neutral mutations during the evolution of coronaviruses like SARS-CoV-2.

Ang Mga baryante ng SARS-CoV-2 ay ang mga baryante ng SARS-CoV-2 na nagsanhi ng pandemya sa mundo bunsod ng COVID-19, bawat bansa ay nakitaan ng mutution mula sa mga strain ng SARS-CoV-2 na nag mula sa Wuhan, Hubei, Tsina noong Disyembre 1, 2019. Ang mga baryante ng SARS-CoV-2 ay ang mga sanga'ng anak dahil sa pag mutate ng birus, ang iba't ibang baryante ay mayroong kakayahang kumopya ng kawangis upang magparami, mayroong mga baryante ay nagkakamali ng pagkopya mula sa strain na ito o tinatawag na "error spelled". ito ay hindi na maaring magpakalat ng baryant.

  1. B.1.1.7 with E484K is separately designated VOC-21FEB-02
  2. Another study[6] has estimated that B.1.1.7 may be 32–104% more lethal
  3. Another preliminary study[25] has estimated that P.1 may be 170–240% more transmissible, with a credible interval with a low probability of 50%.
  4. The reported credible interval has a low probability of only 50%, so the estimated lethality can only be understood as possible, not certain nor likely.
  5. Includes B.1.525 and B.1.526.[13]
