Public healthcare refers to the system of health services provided by the government to ensure that all citizens have access to medical care. This includes hospitals, clinics, and preventive services funded by taxpayer money. The goal is to promote health equity and provide essential services regardless of an individual's ability to pay. In many countries, public healthcare systems are designed to cover a wide range of services, including emergency care, routine check-ups, and vaccinations. These services are often managed by government agencies, such as the National Health Service (NHS) in the United Kingdom, aiming to improve overall public health and reduce healthcare disparities.
