No, but in the absence of that, it seems strange to unpin the denominator while leaving the numerator fixed and then presume that that tells you anything useful.
Setting number of infected humans at 30k, there can be as many as 300 deaths for mortality to be limited to 1%.
Unfortunately, both numbers are fluid, but the assumption is that death count is less so. If the number of deaths is underreported by orders of magnitude then my argument would not stand of course.
EDIT: I consider the number of deaths unlikely to be very underreported based on personal communication with folks in China and HK. There is a fair amount of panic on social media, but “someone I knew died, it seems related to the new virus and deaths may be underreported” so far seems not among the things people panic about. Most panic (some of which is being blown out of proportion for hype and metrics by less than scrupulous sources) appears to be fueled by other things: number of people admitted to the hospital, possible hospital staff infections, and others panicking.
