Which of the following is a method to prevent the spread of infection?

Strict hand hygiene is a fundamental method to prevent the spread of infection because it helps eliminate pathogens from the hands, which are common carriers of germs. Proper handwashing involves using soap and water or an alcohol-based hand sanitizer to remove dirt, bacteria, viruses, and other pathogens. This practice is especially critical in healthcare settings, where the risk of cross-contamination is high. By maintaining clean hands, healthcare professionals and individuals can significantly reduce the likelihood of transmitting infections to themselves and others.

In contrast to hand hygiene, overuse of antibiotics can lead to antibiotic resistance, while increasing exposure to pathogens raises the risk of infection. Wearing loose clothing does not influence infection control measures effectively. Therefore, implementing strict hand hygiene is a highly effective and necessary method for infection prevention.
