Fоllоwing severаl cаses оf а highly contagious infection, a county health department proposes mandatory daily in-person monitoring for exposed residents for 14 days. Epidemiologists estimate that mandatory monitoring would identify approximately 97% of symptomatic cases promptly, whereas twice-daily electronic reporting combined with immediate follow-up would identify approximately 94%. The health commissioner states that mandatory monitoring is therefore ethically preferable because it produces the greater expected public health benefit. Both approaches are legally permissible. Further review shows that mandatory monitoring would require some residents to miss work, arrange transportation, and travel substantial distances, while electronic reporting could be conducted from home. Officials have reliable evidence that both approaches would achieve the department's basic disease-control objective. Which analysis provides the strongest basis for deciding between the two interventions?
