Western propaganda is going batshit crazy and westerns don't even know because the west is so anti-science. So let me just boil it down.
Of course the new strain is more deadly. ANY pathogen that becomes more transmissible is more deadly, because the only way a virus retains the same "deadliness" if its more transmissible is an equivalent offsetting decline in the case mortality rate, which does not seem to have happened here. In fact, a virus that has a doubling of transmission rates is worse than a virus that has a doubling in case mortality, because increases in case mortality means the virus kills more infected before they have a chance to infect others. Meanwhile a virus with increased transmission does not just infect more people from the source, but also more and more people in the subsequent chains. This is literally the biggest cover-up I have ever seen in medical history.
