Public health organizations are groups that work to protect and improve the health of communities. They focus on preventing diseases, promoting healthy lifestyles, and ensuring access to healthcare services. Examples include the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), which provide guidance and resources for public health initiatives. These organizations conduct research, develop health policies, and respond to health emergencies. They also educate the public about health issues, such as vaccination and nutrition. By collaborating with governments and other entities, public health organizations aim to create healthier environments for everyone.
