Which of the following best describes preventive health services?

Preventive health services are primarily concerned with strategies that promote health and wellness and aim to prevent diseases before they occur. This proactive approach includes activities such as vaccinations, health education, screenings, and lifestyle counseling, all intended to reduce the risk of developing health issues.

Choosing this option reflects an understanding that preventive health services prioritize maintaining health and preventing illness over treating existing conditions. This concept is crucial in public health as it seeks to improve quality of life and reduce healthcare costs by preventing diseases rather than addressing them only after they have developed.

The other options do not accurately encompass the essence of preventive health services, as they focus on reactive or curative aspects rather than the proactive measures aimed at wellness and disease prevention.
