What is most important for stopping the spread of disease?

• A. Vaccination
• B. Hand washing
• C. Isolation
• D. Wearing gloves

Answer: (B)

Hand hygiene interrupts the most common route by which germs spread—hands touching surfaces, other people, and faces. Regularly washing with soap and water for about 20 seconds physically removes a wide range of pathogens, making it the most immediate and universal defense in everyday life. When hands aren’t visibly dirty, an alcohol-based hand sanitizer is a quick and effective alternative that reduces germs rapidly. Vaccination is crucial for preventing disease and reducing outbreaks over time, but it doesn’t prevent every exposure or stop transmission in the moment. Isolation helps when someone is infected, but isn’t always practical or sufficient on its own, and wearing gloves can help in specific clinical settings but doesn’t replace the need for proper hand hygiene.
