40-70% infectious means B117 is more deadly
40-70% contagious means B117 iis more transmissible.
What doctors & scientists are worried about with B117 is not the number of severe COVID19 patients in ICU, but
..the number of MILD to MODERATE COVID19+ patients in ALL hospital beds.
Infectious = deadly = more deaths
Contagious = spreads easily = more sick people
B117 is as deadly as COVID19 & D614G, but may be less deadly not more. Yet, it is more CONTAGIOUS than the first 2. COVID-19 Variant 4 from South Africa may be more deadly and may affect Astra Zeneca’s vaccine.
