Public health advocacy involves efforts to promote and protect the health of communities through policy changes, education, and awareness. Advocates work to influence decision-makers and the public on issues such as disease prevention, healthcare access, and environmental health. Their goal is to create healthier environments and improve health outcomes for all individuals. Advocacy can take many forms, including campaigns, community organizing, and collaboration with organizations like the World Health Organization or local health departments. By raising awareness and mobilizing resources, public health advocates aim to address health disparities and ensure that everyone has the opportunity to lead a healthy life.
