I've had a smart idea.
I was blowing my nose and some of the mucus went on my hand and I thought, just imagine if there was a virus that is air borne and 100% fatal and works by metabolising the oxygen in the body into C02 but there is one woman who for some reason is immune but a carrier, like typhoid Mary the Irish cook who spread the disease across New York in the eighteenth century and was locked away and died in isolation where she was forced for the safety of society.
She is absolutely brimming with the virus and whenever she breathes or blows her nose or touches anything with bare hands she spread it.
The scientists and doctors realise something is happening when she lives beyond the day and a half that people with the virus live.
"She doesn't seem to be dying, doctor."
Anyhow, they incubate her and experiment on her, and everyone she sees wears a bio suit and they have to take blood with great care and she doesn't need any treatment, she is kept in an isolated room where she is allowed books and television and is fed regularly but is not allowed outside.
There are groups of human rights people who say she isn't a guinea pig she is a human being, and scientists she has to be isolated and tested to save the human race.
I could involve politics and scientists and the Internet and all kinds of ideas.
And then one night, she escapes.
Remember, this 100% fatal virus that turns the oxygen in the blood to C02 has no effect on her and she can spread it by breathing in a room full of unprotected people.
While she is on the run, she wonders, should she kill herself, even going into shops and handling money can be fatal to those around her, but if she did she would be a biohazard, just lay there with the virus escaping and trying to find other hosts.
And I would call it;
DEADLY INTENTION
Actually, a bacteria would be worse (better?) because a bacteria can live on surfaces for hours if not days when a virus needs a host without a couple of hours or it dies.
