Diagnosing health problems starts with identifying whether illness is present. A test that detects infection provides that identification, which then triggers investigation of exposures and transmission and guides actions to address the problem. A COVID test directly determines if someone currently has the infection, enabling immediate steps like isolation, contact tracing, and appropriate treatment decisions. Hand washing infographics promote preventive behavior but don’t determine if someone is sick. Mandatory flu vaccination is a policy aimed at preventing disease, not diagnosing a current illness. A drive-through flu vaccine clinic is a service delivery method for vaccination, which is about prevention rather than diagnosing an existing problem.
