The golf course community is among several whose associations are alerting residents of positive test results.

The Polo Club of Boca Raton has been hit hard by the coronavirus. The golf course community of 1,700 homes is struggling to cope with 10 confirmed cases. Two of the 10 residents are hospitalized, according to emails obtained by The Palm Beach Post.

Although the Polo Club, on Military Trail near the Clint Moore Road intersection, is not a retirement community, many of its residents are older than 60.

Polo Club officials were not immediately available for comment Sunday but The Post has obtained a series of email alerts sent out by the board of governors to residents from March 21 through March 27. During that six-day period, 10 residents reported to the board that they had tested positive.

The state Department of Health as of Sunday morning had recorded 68 cases in Boca, the most in any Palm Beach County municipality. The department does not follow precise city boundaries but its report indicates generally where cases of infection are.

The Polo Club cases were in the following communities: Knightsbridge, Lakes of Sutton, Huntingdon, Vintage Oaks, Hollows, Ville de Capri and Cocquina. The board has requested that those infected with the virus self-quarantine and contact those who may have interacted with them.

In an email dated Sunday, the board reported that “several are now more than 14 days past learning of their positive result and are without any symptoms or fever for the past 96 hours; these individuals have fully recovered from the virus.”

The board has implemented a “Members Helping Members” program where the club assists residents with the virus by providing them with supplies, food and medicine.

The board has urged that all potential travelers coming to the Polo Club postpone their visit or self-quarantine, regardless of where travel originated. And anyone who traveled to or from New York, New Jersey or Connecticut must contact the Polo Club security office.

The Sunday email noted that in the past 36 hours, no new cases have been reported.

The first two cases were reported on March 21. That’s when the club shut down its tennis and golf facilities, but other country clubs, such as Addison Reserve and Hunters Run had shut down earlier ― Addison Reserve on March 17 and Hunters Run on March 18. Two additional cases were reported each day on March 22, Thursday and Friday.

The board cautioned residents to remain calm and not to spread “unsubstantiated rumors.” Doing so only causes additional stress, and “stress has been shown to contribute to weakened immune systems.”

Other retirement and golf-course communities have also been hit with the coronavirus.

On Saturday, the Valenica Shores Homeowners Association alerted its residents through an email of a case in that retirement community. The resident is in the hospital for a condition unrelated to the virus but tested positive while there, according to the HOA email. The person’s spouse is in isolation. The Shores said it would not disclose the resident’s identity due to privacy laws.

Other retirement communities that have alerted their residents of the presence of the virus include Valencia Palms, Palm Isles, Coral Lakes, Valencia Falls and Majestic Isles. Country clubs that have done so, in addition to the Polo Club, include Hunters Run in Boynton Beach, Wycliffe Golf & Country Club in Lake Worth and Addison Reserve in Delray Beach.
