Though the spread of VSV remained vibrant but since Sept. 03, 2020 no new cases surfaced, as per situation report of USDA, Kansas and Missouri are the only remaining states with VSV-quarantined premises.

Missouri has released one previously VSV-infected premises from quarantine in Dallas County and presently contains five quarantined premises: one in Dallas County, one in McDonald County, one in Ozark County, and two in Phelps County.
