I have often wondered about that. Who knows what they have been injecting these people with? There are another two factors at play... the virus mutates with every infection, with mutation trending away from lethality. That means the people infected at ground zero are always the hardest hit, with the highest death rates. The second factor is as an ACE2 receptor virus, this virus is particularly lethal to Asians. They have three times more ACE2 receptors in their cells than Caucasians do. Asians are much more likely to be overwhelmed than other races in terms of how fast the virus can grow and spread in their bodies, and in terms of ease of transmission between people. Now, Canada has a huge Asian population. Hindus and Chinese. We should expect a mass die off there, centered in these two particular populations, in the cities of Toronto, and Vancouver. It hasn't happened. Why not? There are no signs they are getting sick any faster than anybody else. Yet they still have the excess ACE2 receptors the virus needs to invade a host cell. Meanwhile the government screams the virus is out of control and the whole place is locked down. The math does not add up. However, it might add up if the Wuhan population was already vaccinated with an MRNA introduced genetic modification, before the outbreak began.
