A 35-year old McKinney man has "tested presumptive positive" for coronanvirus, according to county health officials.

This case is unrelated to the other three cases identified in Frisco earlier this week. This man's case will be considered a presumptive positive until the Centers for Disease and Control and Prevention confirms a local lab's findings, the county' website site stated.

The man has no underlying medical condition and is currently self-quarantined in his own home, according to the county.

In addition, Collin County officials have suspended mass gatherings at county facilities due to coronavirus concerns. As a result, the Collin County Master Gardeners' Garden Show scheduled for March 14-15 has been canceled. The event may be rescheduled.
