Community Testing Events to Follow New Sewershed Surveillance Data  

JEFFERSON CITY, MO – Recent results from community sewershed surveillance in Hannibal are indicative of possible increases in COVID-19 transmission in the area. During the weeks of July 12th and 19th, the Missouri Department of Health and Senior Services (DHSS) saw increasing trends in concentrations of COVID-19 genetic fragments in wastewater from the Hannibal (Marion County) sewershed.  Sewershed surveillance metrics are not a direct estimate of the COVID-19 positive human cases in the area. Rather, they provide an indication that COVID-19 transmission is likely increasing among the population in sewershed areas.


During the weeks of July 5th and July 12th, DHSS also saw mutations in genetic fragments in wastewater from Hannibal that suggested the presence of the Delta variant (B.1.617.2), which may be more infectious than the parent strain of the COVID-19 virus or other variants.


DHSS and the Marion County Health Department encourage you to attend an upcoming free testing event, whether you are experiencing symptoms or not.  Community testing events such as this can provide you helpful information to better protect yourself and your family.  It also provides extremely valuable information to public health officials for monitoring COVID-19 transmission in Missouri.

The event in your area will be held on August 4th at the American Legion, 3819 Hwy Mm, Hannibal, from 11am to 7pm.  No registration is required.  For information on this event and other free testing options in Missouri, visit health.mo.gov/communitytest or call 877-435-8411. Translation services are available.
