The Grant County Health District announced Tuesday there were 112 more cases of COVID-19 linked to the Watershed Musical Festival July 30-Aug. 1 in George, bringing the total to more than 230.

Of those, nine Grant County residents have been hospitalized who are in their 40s to 80s.

The GCHD is working with officials to identify other cases, and urging people to self-quarantine and seek testing if they attended the festival, according to a release.
