The number one way to prevent the spread of communicable disease is
A. Disinfecting toys and other objects
B. Washing linens and towels frequently
C.Spraying door knobs with Lysol
D. Hand washing
E. None of the above
D. Hand washing
The correct answer is D. Hand washing.
Hand washing is considered the number one way to prevent the spread of communicable diseases. Proper hand hygiene helps remove germs and prevent their transmission to others. It is important to wash hands with soap and water for at least 20 seconds, especially after using the bathroom, before preparing food, and after coughing or sneezing. Using hand sanitizers with at least 60% alcohol is also effective in killing germs when soap and water are not readily available.
While disinfecting toys and objects, washing linens and towels frequently, and spraying door knobs with disinfectants like Lysol are important measures to maintain cleanliness, they are not the most effective way to prevent the spread of communicable diseases.
