Stand alone

A man named Alex, 34 years old. Has been sent out of his home town, Marsten, for a job in his photography business. He has left his 17 year old son, Caleb, home alone. When Alex is out of town, a two week drive away, a small meteorite lands in Marsten. That carries an airborne disease. When the host is infected, they start to become psychotic and extremely aggressive, and will kill anyone who doesn't have the disease. The host can only be infected when there is an opened wound that leads to the bloodstream. One little cut, and your done.
