Cases of COVID-19 skyrocketed around the area Wednesday as the Lord Fairfax Health District reported 174 new cases, an increase that dwarfed its previous single-day highs of 113 cases on Tuesday and 80 new cases on Saturday.

For the second day in a row, Frederick County set records for new cases. On Tuesday, the county reported a high of 59 new cases and on Wednesday it added 88.

Winchester, Shenandoah County and Clarke County also reported new single-day highs on Wednesday, according to the Virginia Department of Health’s online dashboard at vdh.virginia.gov/coronavirus.

As cases have continued to rise around the commonwealth, Gov. Ralph Northam reminded Virginians in a Wednesday news conference to consider the risks of not taking precautions against spreading the virus.

“I do not intend for things to get worse before taking action,” he said. “That is why we have put new mitigation measures in place to help slow the spread of this virus.”

Included in the restrictions, which took effect at midnight on Monday, are limiting social gatherings to 25 people or fewer. He said the restrictions apply statewide because they’re needed in every region.

Southwestern Virginia is still seeing the highest number of new cases, Northam said, previously explaining that the region lacks the density of hospitals in other regions; but numbers are also rising in every other region, he said.

On Wednesday, Frederick County reported five new hospitalizations and one death. Since the pandemic started, the county has recorded 1,646 cases, 111 hospitalizations and 17 deaths.

Other area localities also reported higher than normal increases.

Clarke County hit a new high for a second day in a row, adding seven cases in addition to Tuesday’s five new cases. The county’s previous high was four cases in one day, which it hit twice in October and twice in November.

Winchester hit a high of 29 cases, up from its previous high of 19 on Saturday.

The district’s seven-day average for new cases is 78.

With Thanksgiving coming up next week, Northam cautioned people to avoid meeting in large gatherings but instead, where possible, meet in smaller groups, meet outside or, safest of all, meet virtually through Zoom or another video chat service.

Additionally, he reminded people to wear masks, wash hands frequently and maintain proper social distancing when around people in the community.

“Do what we all know works,” he said. “Be smart, be careful, and think of those around you.”
