All three global VoCs (B.1.1.7, B.1.351, and P.1) have now been detected in MA. However, unlike B.1.1.7 and B.1.351, P.1 has shown a rapid rise in frequency in the few weeks following its first detection on March 16th, 2021. Phylogenetic analysis of these 54 P.1 genomes from MA, alongside four additional P.1 genomes from neighbouring states (two from Connecticut (CT) and one each from Maine (ME) and Rhode Island (RI)) and 895 other global P.1 sequences from GISAID, 6 1 suggests at least six introductions of P.1 into MA and at least eight introductions of P.1 into the New England region, likely from both international and domestic sources.

Researchers have developed a new artificial intelligence (AI) system which they claim can detect coronavirus by analysing the sound of people coughing.
Scientists at Massachusetts Institute of Technology (MIT) said the AI works because the virus causes temporary muscular impairment which can cause small differences to people’s speech or the sound of their cough – even if they have no other symptoms.
