The WHO 5 moments for hand hygiene are: before touching a patient, before a clean or aseptic procedure, after body fluid exposure risk, after touching a patient, and after touching patient surroundings. Learn when each moment applies, how long to rub or wash, and the exam traps that catch nursing students out.

What are the 5 moments for hand hygiene?

WHO introduced “My 5 Moments for Hand Hygiene” in 2009 so health workers could remember exactly when to clean their hands during care. Each moment answers two questions: when to do it, and who you are protecting.

Why hand hygiene matters in nursing

WHO describes hand hygiene as the single most important measure for preventing infections linked to health care. Nurses touch patients, equipment, and shared surfaces more often than almost anyone else on the ward.

CDC notes that some health workers may need to clean their hands as many as 100 times in one shift. That is why fast, skin-friendly alcohol handrub at the point of care makes such a difference to real-world compliance.

Handrub vs handwashing: which one to use

Both methods work when done properly, but they are not interchangeable in every situation. Use this quick guide.

CDC adds that even with C. difficile, the priority is correct use and removal of gloves and gowns, because spores can stay on hands after any cleaning method. Always follow your facility’s isolation policy.

Hand hygiene technique step by step

WHO’s posters break each method into simple steps. The goal is to cover every surface, including the areas most often missed: thumbs, fingertips, and the spaces between fingers.

Alcohol-based handrub (20 to 30 seconds)

  1. Apply a palmful of handrub into a cupped hand, enough to cover all surfaces.
  2. Rub palm to palm.
  3. Rub the right palm over the back of the left hand with fingers interlaced, then switch hands.
  4. Rub palm to palm with fingers interlaced.
  5. Rub the backs of the fingers against the opposite palm with fingers interlocked.
  6. Rub each thumb in a rotating motion inside the opposite clasped hand.
  7. Rub the fingertips of each hand in circles in the opposite palm.
  8. Keep rubbing until your hands are dry; then they are safe.

Handwashing with soap and water (40 to 60 seconds)

  1. Wet your hands with water and apply enough soap to cover all surfaces.
  2. Follow the same rubbing steps as the handrub technique.
  3. Rinse your hands well with water.
  4. Dry thoroughly with a single-use towel.
  5. Use the towel to turn off the tap.

CDC advises avoiding hot water, because repeated exposure dries the skin. Pat hands dry and use facility-approved hand lotion to protect your skin.

Nursing considerations

Good technique starts before you even reach the sink or dispenser. These points come up in practice and on exams.

Hand hygiene is also part of every procedure checklist you will learn, from neuro checks with the Glasgow Coma Scale to giving medicines from the types of insulin chart.

Exam tips

Board and NCLEX-style questions often test the “why” behind each moment. Keep these memory aids and traps in mind.

Frequently asked questions

What are the WHO 5 moments of hand hygiene in order?

The five moments are: 1) before touching a patient, 2) before a clean or aseptic procedure, 3) after body fluid exposure risk, 4) after touching a patient, and 5) after touching patient surroundings. The first two protect the patient, while the last three protect the health worker and the care environment from patient germs.

How long should you rub alcohol hand sanitizer?

WHO’s handrub technique takes 20 to 30 seconds. Use enough product to cover every surface of both hands and keep rubbing until your hands are completely dry. CDC describes this as about 20 seconds. If your hands are still wet, you have not finished, and if they dry too quickly, you probably used too little.

When should nurses use soap and water instead of hand sanitizer?

Use soap and water when your hands are visibly dirty or soiled with blood or body fluids, after using the toilet, and when spore-forming germs such as C. difficile are suspected or confirmed, especially during outbreaks. Use it too if no handrub is available. Always follow your facility’s infection control and isolation policies.
