Hand Hygiene

Simplest & Most Effective measure to prevent infection

Skin Flora

Resident organisms• In deeper layers of skin• Permanent flora• If disturbed reestablish

themselves• Not removed by routine

hand wash• Usually not associated with

transmission of infection

Transient organisms• In superficial layers of skin• Temporary flora• Usually do not reestablish

themselves• Easily removed by routine

hand wash• Usually associated with

transmission of infection

The health care environment is contaminated. Transient flora is

acquired from patients & environment.

Types of hand hygieneTypes of hand hygieneRoutine hand wash by soap and water: Mechanically removes soil & transient flora

Antiseptic hand hygiene (Alcohol hand rub) by alcohol gel or antiseptic hand wash:

Kills transient flora & reduces resident flora

Surgical hand scrub by alcohol/iodophores: Before surgery (up to elbows)
