America's top infectious disease expert Dr Anthony Fauci has said that the new COVID-19 Omicron variant is in 'fluid motion' in South Africa and the US scientists are in 'very active' communication with their colleagues in that country to test the strain, get facts and find out whether or not it evades the antibodies.
However, the "good news" is that the US vaccines are effective against the Delta variant, said Fauci, the head of the National Institutes of Allergy and Infectious Diseases.

Experts in Singapore, which is seeing a surge in Omicron cases, have warned that the new and supposedly more contagious variant is likely to replace Delta over the coming weeks as the dominant global variant, with the virus being fitter and having a reproductive advantage.
