A coronavirus outbreak at a West Virginia church has grown to 28 cases, Gov. Jim Justice said Monday.

The outbreak that occurred last week at the Graystone Baptist Church in Lewisburg has led to additional available testing for the public in Greenbrier County.

Justice said during his daily news conference that the National Guard conducted decontamination efforts at the church Sunday. The governor said the outbreak was close to his Lewisburg home.

The church said the source of the outbreak is unknown.

It is the fifth virus outbreak involving a West Virginia church. Similar outbreaks have occurred in Boone, Hampshire, Jefferson and Marshall counties.

At least 88 people in West Virginia have died from the virus and about 2,300 have tested positive, state health data shows.
