"Hand Hygiene: Key to Infection Prevention & Control"

By Nicole KingApril 4, 2026

Hand hygiene is a cornerstone of infection prevention and control, playing a pivotal role in reducing healthcare-associated infections (HAIs) and preventing the spread of antimicrobial resistance. This practice, as simple as it may seem, is a powerful weapon in our arsenal against infectious diseases. Let's delve into the importance, techniques, and best practices of hand hygiene in infection prevention and control.

Why is Hand Hygiene Crucial?

Hand hygiene is the most effective way to prevent the spread of microorganisms that cause infections. Healthcare workers' hands can become contaminated with pathogens from patients, the environment, or other sources. Without proper hand hygiene, these microorganisms can be transferred to other patients, leading to HAIs. According to the World Health Organization (WHO), up to 50% of all HAIs can be prevented through rigorous hand hygiene.

Hand Hygiene Techniques

Handwashing

Handwashing is the most common method of hand hygiene. It involves the physical removal of microorganisms from hands using soap and water. The WHO recommends a five-step handwashing technique:
