Brazilian variant 'worrying', says infectious diseases expert

The video discusses the emergence and evolution of virus variants, focusing on the Brazilian variant. It highlights the changes in the virus's spike protein, which increase its infectiousness and potentially affect vaccine efficacy. The importance of sequencing the viral genome to track the spread of these variants is emphasized, with the UK leading in sequencing efforts. The situation in Brazil is critical, with rapid virus spread, but the exact role of the Brazilian variant is still being studied.

Why is the UK considered to be effective in sequencing the virus genome?

What challenges are faced in determining the spread of the virus in Brazil?
