Apply the criteria to each of the policy alternatives of the covid 19 using the most appropriate methodology. This should be done in a transparent manner, with all data and results listed explicitly. If possible, score the alternatives. Summarize comparative assessment using a matrix or similar summary display.

Policy Alternative 1: Stay-at-home Orders

Criteria:
1. Effectiveness in reducing spread of virus
2. Economic impact
3. Social impact
4. Feasibility of enforcement

Methodology:
1. Effectiveness: Compare infection rates before and after implementation of stay-at-home orders in various regions.
2. Economic impact: Analyze unemployment rates and GDP changes in regions with stay-at-home orders.
3. Social impact: Survey residents in regions with stay-at-home orders on mental health and social well-being.
4. Feasibility: Assess compliance rates and enforcement efforts in regions with stay-at-home orders.

Results:
1. Effectiveness: Stay-at-home orders have been shown to significantly reduce virus spread in regions where implemented.
2. Economic impact: There is a negative economic impact due to increased unemployment, but government support packages can mitigate some of the effects.
3. Social impact: Residents report negative impacts on mental health and social well-being due to isolation.
4. Feasibility: Enforcement of stay-at-home orders varies by region but overall compliance rates are relatively high.

Policy Alternative 2: Mass Testing and Contact Tracing

Criteria:
1. Effectiveness in identifying and isolating cases
2. Economic impact
3. Social impact
4. Feasibility of implementation

Methodology:
1. Effectiveness: Compare testing and contact tracing rates in regions with different strategies.
2. Economic impact: Analyze costs associated with mass testing and contact tracing compared to economic benefits of quicker containment.
3. Social impact: Survey residents on their experiences with testing and contact tracing efforts.
4. Feasibility: Assess infrastructure and resources needed for widespread testing and tracing.

Results:
1. Effectiveness: Mass testing and contact tracing have been effective in identifying and isolating cases, but challenges include privacy concerns and delays in test results.
2. Economic impact: Upfront costs of testing and tracing are high, but faster containment can lead to reduced economic impact in the long term.
3. Social impact: Residents have mixed feelings about testing and contact tracing efforts, with some expressing concerns about privacy.
4. Feasibility: Implementation of mass testing and contact tracing requires significant resources and coordination, but can be scaled up with proper planning.

Summary Matrix:

Policy Alternative | Effectiveness | Economic Impact | Social Impact | Feasibility
Stay-at-home Orders | High | Negative | Negative | High
Mass Testing and Contact Tracing | High | High | Mixed | Moderate
