The data comes in a couple of weeks down the line, not months. If you are not testing enough (they are), then your death rate is exponential 14 days lagged. Japan is clearly doing a good job.
Very good point. I think it's closer to 21 days lagged, because the vast majority (95th percentile) have a 6 day incubation period and a shorter low symptom to death period, but regardless it is clearly not months.
5-14 day incubation period. 5-7 day low symptom period. 5-14 days to death.
