| 11. |
What is the role of disease surveillance in epidemic prevention? |
| A. | It helps in developing new vaccines after an epidemic has occurred. |
| B. | It is only useful for tracking the spread of pandemics, not epidemics. |

| D. | It helps in early detection of outbreaks and implementation of control measures. |
| Answer» D. It helps in early detection of outbreaks and implementation of control measures. | |
| Explanation: Disease surveillance helps in early detection of outbreaks, tracking disease spread, and implementing timely control measures, thus playing a crucial role in epidemic prevention. | |
| 12. |
How can technological solutions contribute to minimizing the burden of epidemics? |
| A. | By replacing the need for human healthcare workers |
