Just as important as the death rate are things like the infection rate, incubation period transmissibility during incubation. So far on balance Covid19 seems nastier than the ones you referred to. Using a back of the envelop calculation i estimated about 100000 people in just Oz will die in the first wave of COVID19 unless significant steps are taken. A few days later medical experts came out with the same number (96000). The final death rate could be much higher because depending how quickly it is allowed to develop because it can easily overwhelm medical facilities causing many other people with serious medical problems to also die because the can’t be attended to. Just like any pandemic this is also just the first wave until a vaccine is available it will revisit us and reap more victims a number of times.
