Recent wastewater surveillance report indicated a 30% decline in Covid-19 virus load for the past two weeks, the Star Tribune reports.

Quoting Steve Balogh, a research scientist at the treatment plant, the Tribune writes “The decline is a statistically significant movement to a lower level, suggesting fewer COVID infections in the Metro Plant service area. However, he cautioned that we can’t predict whether this trend will continue or reverse itself.”

During the past two years of Covid pandemic, the wastewater surveillance data indicated increased in Covid virus load, however this year’s virus load declined is reportedly attributed to increased level of immunity as a result of vaccinations and natural infections. “Wastewater analysis for viral levels is considered a leading indicator of pandemic activity because it isn’t affected by the number of COVID-19 tests performed,” writes the Tribune.

The Tribune writes “Infection data for more recent days is incomplete, but Mayo Clinic’s 14-day forecast for Minnesota predicts continued progress in September.

According to Tribune, University of Minnesota’s wastewater sampling results also reportedly showed a decine covidvirus load throughout the state.
