Catching up on case counts from over the weekend, Martha’s Vineyard boards of health reported 19 new confirmed positive coronavirus cases Monday, as the winter solstice arrives and the Island heads into the Christmas holiday.

Numbers released Monday by Tisbury health agent Maura Valley account for cases reported since Dec. 18. On Saturday there were nine new cases, four from testing at the Martha’s Vineyard Hospital and five from TestMV, the free testing site at the regional high school.

On Sunday five cases were reported, two from the hospital and three from TestMV. On Monday another five cases were reported, one from the hospital and four from TestMV.

There were three people hospitalized with the virus over the weekend, the most hospitalizations at one time since the outbreak began.

One patient was discharged Sunday, leaving two Covid-19 inpatients. One is in fair condition, and the other is in good condition, head of nursing Claire Seguin said. There have been no new Covid patient transfers as of Monday, Ms. Seguin confirmed.

Total case counts to date on the Island stand at 499, with 468 confirmed positives from PCR tests. The rest were diagnosed symptomatically or through antibody testing.

To date the high school test site has tested 26,891 patients, while the hospital has tested 9,588 patients. TestMV is focued on testing asymptomatic patients, while the hospital only tests people with symptoms.

After a summer and early fall of low case counts, the Vineyard began seeing a surge in cases just after Thanksgiving. Case counts have remained steady since then as the virus continues its assault around the country and around the globe. A handful of clusters have been reported on the Vineyard, including one from a wedding in October, one at Cronig’s Market in November and a recent cluster stemming from at at-home bible study group.

The first vaccines arrived on the Vineyard last week and were administered to hospital front line workers.

With vaccine distribution still in the early stages nationwide, there has been no further information about how the vaccine will administered more broadly to the general population on the Vineyard, once supplies are in hand.
