Hand Hygiene: When and How to Decontaminate After Contact with Bodily Fluids

Hand Decontamination After Bodily Fluid Exposure

Yes—always decontaminate your hands after contact with any body substance (blood, urine, feces, saliva, vomit, wound drainage, etc.), regardless of visible soiling.

Why It Matters

• Microorganisms are invisible; absence of visible soil ≠ absence of pathogens.
• Prevents cross-contamination to patients, surfaces, and yourself.
• Complies with Standard Precautions (CDC/WHO).

Correct Technique

1. Alcohol-Based Hand Rub (ABHR): Preferred for routine decontamination if hands not visibly soiled. Apply palmful, cover all surfaces, rub until dry (≥20 sec).
2. Soap & Water: Required when hands are visibly soiled, after caring for C. difficile or norovirus patients, or before eating/after restroom. Wet, lather 20 sec, rinse, dry with disposable towel.
3. Glove Use ≠ Hand Hygiene Substitute: Perform hand hygiene before donning and immediately after removing gloves.

Key Moments (WHO 5 Moments)

1. Before patient contact
2. Before aseptic task
3. After body fluid exposure risk
4. After patient contact
5. After contact with patient surroundings

Consistent hand hygiene is the single most effective measure to prevent healthcare-associated infections.
