Which method is most effective for reducing the spread of infection between individuals?

1. Hand sanitizer

2. Hand-washing

3. Use of gloves

4. Use of gowns

The correct answer is: Hand-washing

Hand-washing is widely considered the most effective method for reducing the spread of infection between individuals. This practice involves thoroughly washing hands with soap and water for at least 20 seconds, which removes pathogens, dirt, and contaminants from the skin. The mechanical action of scrubbing, combined with the detergent properties of soap, breaks down oils and helps to dislodge viruses and bacteria, effectively reducing their presence on the hands. While hand sanitizers are a convenient alternative when soap and water are not available, they may not be as effective at removing all types of germs, especially in the presence of dirt or organic material. The use of gloves provides a barrier but does not eliminate the need for hand hygiene; improper glove use can lead to contamination. Similarly, gowns are protective garments that may prevent transfer of pathogens through clothing but do not directly affect hand hygiene. Therefore, hand-washing remains the gold standard in infection control.
