#DurhamRegion COVID-19 Wastewater Viral Signal
🧵THREAD 1/5🧵

*The lines on the chart indicate the statistically smoothed wastewater signal (gene copies/mL on log10 scale).
*The shaded area (blue) is the 7-day moving average of new reported COVID-19 cases by onset date.

This chart specifically represents the Bayly wastewater catchment area. Use the map above for geographical reference. I have highlighted this catchment area as it has seen a spike in detected gene copies of COVID-19.

2/5

Chart interpretations:
It is clearly noticeable in the Bayly chart, and the chart in the 1st tweet that the concentrations of COVID-19 in wastewater started to increase in November before we started to see exponential growth in our reported cases.

However, this is not the only place in Ontario that has experienced a sudden jump. The MOH in Peterborough @twpiggott says that the slight increase in viral load detection is due to students returning to in-person learning.

This data will be interesting to follow over the coming weeks as the government of Ontario has relaxed some of the restrictions.
