Health agencies are organizations that work to protect and improve public health. They monitor health trends, provide information about diseases, and develop policies to promote healthy behaviors. Examples of health agencies include the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). These agencies also respond to health emergencies, such as outbreaks of infectious diseases. They collaborate with governments, communities, and other organizations to ensure access to healthcare services and to educate the public about health issues. Their goal is to create healthier environments and improve the overall well-being of populations.
