# Metrics to relate COVID-19 wastewater data to clinical testing dynamics

## Introduction
The emergence of COVID-19 has highlighted the importance of wastewater surveillance as a complementary tool to clinical testing.

## Key Metrics
1. **Virus Concentration**: Understanding the concentration of viral RNA in wastewater samples helps in assessing community transmission levels.
2. **Temporal Trends**: Analyzing changes in virus concentration over time can correlate with clinical case trends.
3. **Geographical Distribution**: Mapping virus concentration across different regions provides insights into localized outbreaks.

## Methodology
- **Sample Collection**: Describes protocols for collecting wastewater samples.
- **Testing Techniques**: Overview of RT-qPCR methods for detecting viral RNA.

## Results
### Case Studies
- Case study 1: Correlation of wastewater data with clinical case numbers.
- Case study 2: Application in urban vs. rural settings.

## Conclusion
Wastewater monitoring is a valuable tool for public health surveillance that can enhance understanding of the COVID-19 dynamics.
