Viral spread in latest Minnesota COVID-19 wave more of a mystery
September 22, 2021
Minnesota's tracking of how and where people are infected with the coronavirus has plummeted in the latest COVID-19 wave, with 80% of infections identified in August coming from unknown sources.
The change from an unknown rate of 41% at this time one year ago reflects an increase in social activities that makes it hard to pinpoint where someone got infected, but also a pullback of state contact tracing in the era of COVID-19 vaccinations. A COVID-weary public also isn't helping as much with contact tracing - the formal process to identify how someone was infected and who else might have been exposed to the virus.
State Health Commissioner Jan Malcolm said it remains important to understand the spread of COVID-19 - which has caused more than 8,000 deaths in Minnesota - but that the source of every infection isn't needed anymore to understand how and where the coronavirus is transmitted.
