While the Centers for Disease Control and Prevention, or CDC, continues to list Greene County as having a “low” community level for the coronavirus based on a revised metric adopted earlier in the year, recent local wastewater samples show an increase in COVID-19 viral shedding in the village over the past couple of weeks.

According to the Ohio coronavirus wastewater monitoring network website, the wastewater samples are examined for gene copies or fragments of the virus that cause COVID-19. That data is collected in a way that pinpoints an increase within a community’s watershed boundary.

An email dated Tuesday, April 12 from representatives of the Ohio Department of Health, or ODH, to Village Manager Josué Salmerón, reported that the viral shed in Yellow Springs’ wastewater “increased tenfold” in the first week of April.

The ODH website says that increases and decreases are determined based on average samples.

The website reads, in part:

“An arrow symbol is listed next to the facility name that describes if the flow adjusted gene copies (shown in million gene copies per day) are increasing, decreasing or steady. This is done by comparing the average of the last two samples with the average of the prior third and fourth sample in order to determine the percentage of change between the averages.”

According to the email to Salmerón, the flagged samples were taken between March 28 and April 6. Using the ODH reporting model, Yellow Springs has had an 121% increase. Springfield has also experienced a significant increase of 135% as of April 6. More recent data has not been released by the state.
