Which hygiene practice is crucial for preventing the spread of germs?

Handwashing with soap and water or using hand sanitizer is vital for preventing the spread of germs because it effectively eliminates pathogens from the skin. Proper hand hygiene is one of the most fundamental and proven methods to prevent infections, especially in healthcare settings. When hands are washed thoroughly with soap and water for at least 20 seconds, or when an alcohol-based hand sanitizer with at least 60% alcohol is used, it significantly reduces the microbial load and the likelihood of transmitting infections.

This practice addresses the transfer of germs that can occur through direct contact with others or surfaces. While wearing gloves, using disinfectant wipes on surfaces, and wearing masks are important measures for infection control, they are not as universally effective in preventing the immediate transfer of bacteria and viruses as proper hand hygiene. Gloves can become contaminated, and masks primarily help to prevent airborne transmission rather than hand-to-hand contagion. Thus, prioritizing hand hygiene provides a comprehensive layer of protection against the spread of germs.
