The coronavirus is throwing new challenges every day. Recently, the World Health Organization (WHO) confirmed the possibility of a recombinant virus. Last week, the WHO confirmed the emergence of a new recombinant virus called the BA.1 and BA.2 Omicron strains.
On March 19, the WHO tweeted an explanation of a combination of Delta AY.4 and Omicron BA.1.
“Recombinants are expected because # SARSCoV2 is now widespread among humans and many animal species. Testing, surveillance (including ILI and SARI), sequencing and data sharing are still important to keep track of epidemics and take early steps when new forms emerge.” Soumya Swaminathan, chief scientist of the World Health Organization, tweeted on Sunday.
