What makes you think that? She was out driving and shopping until late afternoon on the 11th.
Nobody said that they thought she died on the 11th. They said that was the last date that she was known to be alive.
The ME gave a clear description of the progress of hantavirus pulmonary syndrome.
Flu-like symptoms which can last three to six days.
Then death can follow in 24 to 48 hours.
So if she was well enough to go out on the 11th, I can't see her dying less than four days later, and possibly up to a week.
If her initial symptoms were relatively mild, she could have still been looking after Gene to a degree.
Dr Jarrell: "The question was regarding shortness of breath with Hantavirus, and what kind of medical episode would we expect from somebody found on the floor? And I think to be able to answer that question fairly, it can go back to Hantavirus infection, which initiates with what's called a prodromal phase. That's initially flu-like symptoms, where a person has fever and muscle aches, they don't feel well, after of course being exposed to rodent excrement, and that phase can last roughly three to six days, and then they can transition to that pulmonary phase where they have fluid in their lungs and around their lungs, and at that point a person can die very quickly within 24 to 48 hours, roughly speaking, without medical treatment."
