Preventive care refers to any health-related intervention that helps prevent a person from contracting an illness. Preventative care is a precautionary measure rather than a treatment. Two basic examples are health screenings and blood tests.
Physicals and other medical exams are performed before any symptoms appear, which may keep a person well without the need for further, and perhaps more invasive, medical treatment. The U.S. Department of Health and Human Services urges Americans to get vaccinations like flu and pneumonia shots to prevent them from getting these diseases. Blood pressure, diabetes and cholesterol tests can reduce the risk of having a stroke and other illnesses that may result when left unchecked, according to the Mayo Clinic.
