There will be no admittance at the two front doors.  The EAST side door will be the entry and exit for persons receiving services at the health department.  The doors will remain locked. Please call 573-221-1166 to gain entrance or service. Please continue to make appointments, as necessary.  We are continuing to require masks properly worn inside the building.
