Sewage SARS-CoV-2 RNA and COVID-19 Cases in Lavras, Brazil

Wastewater samples from a sewage treatment plant in Lavras, Minas Gerais, Brazil, collected between the 19th and 25th epidemiological weeks. The dataset correlates SARS-CoV-2 RNA concentration with COVID-19 case numbers and physical-chemical sewage variables like pH and chemical oxygen demand. The study was conducted by Mariana Aparecida de Freitas Abreu.

Use Cases

• Correlating viral load in wastewater with confirmed COVID-19 case numbers based on epidemiological bulletins.
• Analyzing the relationship between SARS-CoV-2 presence and sewage characteristics like pH and chemical oxygen demand.
• Evaluating the impact of pandemic countermeasures on viral concentration in sewage over time.
• Developing models for early outbreak detection based on wastewater monitoring data.

Strengths

• Data includes a direct correlation analysis between viral load and confirmed cases using Spearman's test.
• Samples were processed using standardized methods like electronegative membrane adsorption and RT-qPCR.
• Covers a specific time period (epidemiological weeks 19-25) in a defined municipality.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Data is limited to a single municipality, which may not be generalizable.
• Last update date is unknown; freshness unverified.
