ern

ern estimates the effective reproduction number (Rt) from clinical and wastewater surveillance data to assess epidemic states and public health intervention effectiveness.

Key Features:

• Rt Estimation from Wastewater Data: Estimates the effective reproduction number from pathogen wastewater concentration data.
• Rt Estimation from Clinical Data: Estimates the effective reproduction number from aggregated clinical surveillance data.

Scientific Applications:

• Epidemic State Assessment: Determines whether an epidemic is growing (Rt above one) or under control (Rt below one).
• Public Health Intervention Evaluation: Assesses the effectiveness of public health interventions undertaken in response to an epidemic.
• Wastewater-Based Epidemiological Surveillance: Supports Rt estimation from pathogen wastewater concentration, a surveillance data stream with demonstrated utility during the COVID-19 pandemic.

Methodology:

Statistical estimation of the effective reproduction number from real-world wastewater or aggregated clinical surveillance data.
