Community Health Workers (CHWs) are ordinary members of the community who work with the local health care system in both urban and rural environments. CHWs usually share ethnicity, language, socioeconomic status, and life experiences with the community members they serve. CHWs offer interpretation and translation services, and culturally appropriate health education and information. They also help people get the care they need, give informal counseling and guidance on health behaviors, advocate for individual and community health needs, and provide some direct services such as first aid, checking vital signs, and other health screening services. Since CHWs typically reside in the community they serve, they have the unique ability to bring information where it is needed most. They can reach community residents where they live, eat, play, work, and worship. CHWs are frontline agents of change, helping to reduce health disparities in underserved communities.
