What does health surveillance aim to achieve?

Health surveillance primarily aims to monitor health trends in populations. This involves the systematic collection, analysis, and interpretation of health-related data to identify patterns or changes in health status over time. By monitoring these trends, public health officials can make informed decisions about resource allocation, implementing interventions, and formulating policies to address health issues.

Effective health surveillance helps in early detection of outbreaks, understanding the epidemiology of diseases, and assessing the effectiveness of health programs. It plays a critical role in guiding public health actions and ensuring that populations receive appropriate care based on identified needs.

While the other options, such as implementing new healthcare technologies, managing healthcare costs, and enhancing public awareness, are important components in the broader healthcare system, they do not directly capture the primary goal of health surveillance, which is centered around monitoring and analyzing health data to guide health interventions.
