Nobody I know had it either.
I think they are full of it.
All but one in our big family had it. Our son almost died and was hospitalized due to H1N1. On its heals he caught another flu bug that again put him in even more grave condition because he had no reserve. Life has permanently changed because of this. Lord willing he will do more healing.
Glad you and yours were spared. It can be really ugly. Even our healthy daughter said it was like all other “bugs” she ever had all wrapped up into one flu.
