Edexcel IGCSE Practice Test 2026: Changes in Medicine 1845-1945

Community health workers played a crucial role in public health after 1945, primarily by implementing health education and preventative measures within communities. Their work focused on raising awareness about health issues, facilitating access to healthcare resources, and promoting healthy practices among community members. This was particularly important in the post-war era when there was a growing emphasis on preventive healthcare as a means to improve overall public health outcomes and reduce the incidence of diseases.

By engaging directly with the community, these workers were able to tailor health messages to meet local needs, foster trust among residents, and encourage participation in health programs. This approach helped to address public health challenges such as communicable diseases and maternal and child health, and it laid the groundwork for modern public health initiatives.

In contrast, the other roles mentioned do not encompass the primary focus of community health workers. Conducting scientific research in laboratories is typically the role of scientists and researchers rather than community health workers. Focusing solely on individual healthcare needs somewhat contradicts their broader community-oriented mission. Working exclusively within private practices limits the scope of their contributions, whereas community health workers are primarily concerned with public health at a community level, rather than in a private practice environment.
