Relacionado: Increased transmissibility and global spread of SARS-CoV-2 variants of concern – “Estimated transmissibility increases of alpha 29% (95% CI: 24–33), beta 25% (95% CI: 20–30), gamma 38% (95% CI: 29–48) & delta 97% (95% CI: 76–117)”. E WHO renames COVID-19 variants with the Greek alphabet (i.e., Alpha, Beta, Gamma, etc), making them simple, easy to say and remember. The naming system aims to prevent calling COVID-19 variants by the places where they are detected, which is stigmatizing & discriminatory.

India's official COVID death toll is 400,000.
But new research shows the death toll could be much higher, up to 4 million.
