What is one effective method to prevent communicable diseases?

Practicing good hygiene, such as regular handwashing, is a highly effective method to prevent communicable diseases because it significantly reduces the spread of pathogens. Germs can be transmitted through direct contact, surfaces, and various other means, and regular handwashing with soap and water is proven to remove these harmful microorganisms from the hands.

This practice is especially important in healthcare settings, food preparation areas, and during flu season when the risk of infection is heightened. Handwashing not only protects the individual but also helps prevent the spread of diseases to others, creating a healthier community overall.

While avoiding physical contact can reduce exposure, it is not always practical or possible in daily life. Vaccination is important for disease prevention, but it should be administered before exposure to the illness rather than in response to sickness. A balanced diet contributes to overall health but is not a direct preventative measure against the transmission of communicable diseases like good hygiene practices are.
