According to the World Health Organisation (WHO), the COVID-19 Omicron is a ‘Variant of Concern’ (VOC). Although information about the Omicron variant is still evolving, it is known that the virus is more transmissible than the Delta variant. Again with respect to immunity, the Omicron variant is said to escape immunity and makes vaccination less effective. And fortunately though, the Omicron variant is believed to be milder in severity than the Delta variant, principally because of the benefit of vaccination. On transmissibility of Omicron, evidence across the world reveals that it spreads significantly faster than the Delta variant as WHO earlier observed.
