Social media influences public health communication by enabling rapid dissemination of information and fostering community engagement. Platforms allow health organizations to share accurate health messages and updates directly with the public, increasing awareness of issues such as vaccination, disease prevention, and mental health. Social media also facilitates dialogue, allowing users to share experiences and address concerns, thereby enhancing trust. However, it can also spread misinformation, making the role of health professionals crucial in steering conversations and providing evidence-based guidance. Overall, social media is a powerful tool in public health outreach.
