Mortality rate may be unknown. But we know it's killed at least a half million in the US alone, 3 million worldwide. There are also deaths not associated with Covid 19 but caused by it (they didn't get a test before or after death). That's still the highest rate of death we've seen since the last pandemic (spanish flu) caused in a single season by a virus. So yes it is dangerous.
