Question

which method helps prevent communicable diseases? a. immunization exemptions b. disease diagnosis c. mandatory vaccinations d. hospitalization

Explanation:

• Immunization exemptions (A): Allowing exemptions would reduce the number of vaccinated people, increasing the risk of disease spread.
• Disease diagnosis (B): Diagnosis is for identifying an existing disease, not prevention.
• Mandatory vaccinations (C): Vaccines train the immune system to recognize and fight pathogens. Mandatory vaccination increases the proportion of vaccinated individuals in a population, creating herd immunity which helps prevent the spread of communicable diseases.
• Hospitalization (D): This is for treating sick individuals, not preventing disease spread.

Answer:

C. Mandatory vaccinations
