COVID-19: New Omicron sub variant discovered in Israel
The sub variant is thought to have originated in India, and has been found in Canada, Denmark, Singapore, China and Australia.
Some 20 cases of a new sub-variant that developed from the original Omicron variant have been discovered in Israel, KAN reported on Thursday evening.
The sub-variant, known as BA2, was discovered during genetic sequencing of sample COVID patients. It contains more mutations than the original Omicron and may be more violent. However, the danger posed by the new sub-variant is still uncertain, and the Health Ministry's coronavirus outreach headquarters clarified that there was no evidence that BA2 behaved differently than Omicron.
BA2 was first seen in China a few weeks ago, and is suspected to have originated in India. It has also been observed in Denmark, Australia, Canada and Singapore, Kan reported.
