WHO's director of emergencies, Michael Ryan warned that as the virus continues to evolve, the world "cannot simply afford to lose sight of it".

BA.2 has started outcompeting BA.1, suggesting that it is more transmissible than the original Omicron, the researchers said.

Last week, Europe and central Asia saw 27,000 additional Covid-19 deaths and 2.6 million new cases.

The ICMR-Regional Medical Research Centre, NE, Dibrugarh has developed a novel technology -- real-time RT-PCR assay for detection of Omicron (B.1.1.529) variant of SARS-CoV2 and a kit for the same.

According to the global health body, the hyper mutant variant has spread to 77 countries so far.

Closing of schools across the world should be the last resort in the fight against the fast-spreading Omicron Covid-19 variant, outgoing Unicef Executive Director Henrietta Fore said.

The study was conducted using AlphaFold2 - a neural network-based deep learning model created by Google DeepMind - which can predict protein structure based on the genetic code.

The ILS Director said that compared to the first and second wave, both the Centre and Odisha government have adopted a proactive approach and focus is being given on testing and tracking of the returnees.

Many of the changes have been found in variants such as Delta and Alpha, and are linked to heightened infectivity and the ability to evade infection-blocking antibodies.

Countries must enhance surveillance and sequencing. They should assess the risk of importation through international travel based on updated information on circulating variants and response capacities, and take measures accordingly.

The study also looked at the effectiveness of booster doses at preventing infection, finding that the risk of infection was around three times lower in those who had received a third dose, compared to those who had received two.
