disease elimination

Disease elimination refers to the absence of a disease within a specific region, while eradication means the disease no longer exists anywhere globally. Smallpox is the only human disease to have been completely eradicated worldwide through vaccination and surveillance. Other diseases, like malaria, cholera, polio, measles, and rubella, have been eliminated from various regions, including the United States and the Americas.1

The debate surrounding elimination and eradication often centers on the role of vaccination versus improved sanitation and clean water. While vaccination is a key tool, maintaining elimination status, such as for measles, can be challenging due to outbreaks. Public health efforts focus on preventing disease, prolonging life, and promoting health through various strategies, including vaccination, sanitation, and organized health services.12
