LITTLE SILVER - The borough has announced a third "presumptively positive" case of COVID-19, or novel coronavirus.

"The new presumptive positive is an adult female," according to an announcement Saturday on the borough's website. "How she contracted the virus is the subject of further investigation, and those she has had contact with are being identified and notified."

The first coronavirus patient in Little Silver was a 27-year-old man who began to show symptoms Feb. 29 following a conference in Boston run by pharmaceutical company Biogen, state Health Commissioner Judith Persichilli said earlier this month. She said 170 attendees at the five-day conference had also been "presumptive positive" coronavirus patients.

The second presumptive positive case was a family member of the first patient, according to the Monmouth County Health Department. That patient was a Red Bank Regional High School student. The school immediately shut down for cleaning, and has since moved to online instruction.

Borough officials said they would provide more details on the new case as they become available and asked residents to continue to take precautions - hand-washing, canceling group activities, practicing so-called "social distancing" and preventing children from congregating - to prevent the possible spread of the respiratory illness.
