Public health is when people work together to keep everyone healthy. A healthy community is one with healthy people, and this is achieved by working together to prevent diseases, keep the environment clean, and provide access to health care for everyone who needs it. Public health workers work to promote healthy lifestyles, stop the spread of disease, and provide education about health and safety. They also work to make sure that communities have access to clean water, safe food, and quality healthcare. Public health also helps to identify health problems in communities, such as pollution, drug abuse, and lack of health care services. By working together, public health professionals can help to make sure everyone in the community has what they need to stay healthy and safe.
