I think the odds ARE indeed tougher of this happening than winning the powerball and by quite a large margin but I cannot confirm 100%, but hear me out:
If the odds of the hitting the Powerball are 1 in roughly 292.2 million and there are 340 million people in the U.S. with 52 weeks a year and 2 days a week where the results are given then that's 104 opportunities a year.
Now, use the same data for the U.S. population and the fact that since 1993 (on average) there are only 20-50 confirmed cases a year. Now, add in a mortality rate of roughly of 35% (or 1 in 3) people dying who contract it. Once you do that, now lets say we use the worst case scenario: which is 50 cases a year since 1993 and only 52 weeks a year.
There is still only 1 person a week "contracting" the virus a week in the United States, but the odds get even crazier when you factor in mortality rate of the virus of 35% and remember we are using the worst case scenario data over a 32 year average.
If we used the 20 cases a year data it would be even crazier. So you mathematicians check my math to see if it's mathing but at this point I believe her odds of dying from this would be pretty close to her winning the powerball twice in 1 year.
So basically if you use the low end data of contracted hantavirus cases (20 a year) and a 1 in 3 chance of dying from it then there's roughly 7 people A YEAR who actually die from this.
Crazy odds and not sure I'm buying it.
