Community health workers connect individuals and families with essential health services, promote behaviour change, and support public health interventions at the grassroots level. They conduct household visits, deliver health education, assist with screenings, and provide culturally relevant guidance tailored to community needs. Their work is foundational to maternal-child health, immunisation outreach, chronic-disease support, and emergency response. As nations expand community-based healthcare models, demand for trained CHWs continues to rise globally. Their effectiveness relies on communication skills, trust-building, and strong collaboration with nurses, public-health teams, and local organisations.
