Hi
OK, with blood you have to be very careful. Although HIV only lasts a few days outside the body, there may be other BBP's (Blood bourne Pathogens) present, also a small stain on the surface (size of a coin) can be the size of a dinner plate underneath.
Other factors:
Is she on any medication?
Does she have cancer or any other Infection (Hepatitis)?
Any drug usage?
Has it penetrated the floor boards or sub structure?
You HAVE to know these answers before proceeding.
Clean-up:
Sanitise the area first, either use a Biocide (15 min dwell time) or a biological soap powder.
Always use cold water (protein will congeal under temperature)
A stain may remain even though the area is clean, blood chemically reacts and although sanitized and clean, the stain may remain.
Blood and body fluids will emit pheromones on the air attracting flies which will lay maggots, you must may sure all blood is cleaned up.
Good luck
Martin
