Community Testing Events to Follow New Sewershed Surveillance Data  

JEFFERSON CITY, MO – Recent results from community sewershed surveillance in Hannibal, MO are indicative of possible increases in COVID-19 transmission in those areas. During the week of April 5, 2021, the Missouri Department of Health and Senior Services (DHSS) saw elevated and increasing trends in concentrations of COVID-19 genetic fragments in wastewater from Hannibal, MO (Marion County) sewersheds.  Sewershed surveillance metrics are not a direct estimate of the COVID-19 positive human cases in these areas. Rather, they provide an indication that COVID-19 transmission is likely increasing among the population in these sewershed areas.


DHSS and the Marion County Health Department encourages 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 April 21, 2021 at the

American Legion, 3819 Highway MM,

Hannibal, MO 63401,

from 11a.m. to 7p.m. 


No registration is required.  For this event and other free community testing events in Missouri, visit health.mo.gov/communitytest or call 877-435-8411.
