It doesn't sound like Erin's mother has a mild case of west nile virus. Yes, it's treatable but it depends how bad it really is as to the outcome. Hopefully Erin's Mom will recover just fine. A person over 50 died from it not far from our area. Nothing to fool with at all. Texas is doing a lot of spraying now as it really has raised havoc there.
It hardly affects some people and others it can be bad.

I hate mosquitoes too. We never used to have all this stuff around.
