Specialists do not know precisely how contagious the extremely mutated omicron variant is, however the virus’ spike protein — which binds to human cells — has mutations related to greater transmission and a lower in antibody safety.

Leong agreed {that a} three-dose vaccine routine would possible shield in opposition to extreme illness, however identified that many nations nonetheless have low vaccination charges.
He mentioned omicron is “threatening the entire world” with a sudden surge in circumstances, and health-care methods could possibly be overwhelmed, even when just one% or 2% of the circumstances find yourself in hospital.
Omicron was first detected in South Africa and was designated a variant of concern by the WHO final week. It has since been reported in a number of different locations, together with Hong Kong, the Netherlands and Portugal.
For now, nevertheless, Leong mentioned we should always proceed to roll out vaccinations, preserve our distance, put on masks, and never be overly involved.
