All state courthouses in New York have begun to restrict entry to people with flu-like symptoms or potential exposure to COVID-19, a spokesman for the state court system said Thursday.

Red signs reflecting the new rules will be posted on courthouse doors around the state by Friday, spokesman Lucian Chalfen said.

The signs are the same as those posted on the doors of New Rochelle's city and family courthouses Wednesday.

People who had scheduled appearances in court but are affected by the entry restrictions can call a courthouse-specific phone number for instructions, and they won't be penalized for missing court in that circumstance, according to the signs.

National Guard troops were also deployed to New Rochelle this week, and starting Thursday, the Westchester County town is home to a one-mile "containment area" designed to hamper the spread of the new coronavirus, Gov. Andrew Cuomo announced.

The statewide number of confirmed cases was around 325 as of Thursday, officials said.

In a memo to employees of the state court system Thursday, Chief Administrative Judge Lawrence Marks said cases in which a courthouse visitor has been diagnosed with COVID-19 will be announced through court websites, whether the diagnosis came before or after the person's visit.

Marks also said judges should consider applications for postponements and consider the use of remote appearances "to the fullest extent permitted by law." All non-essential events planned in courthouses have been postponed, he said, and the court system is reviewing prisoner transport procedures and court procedures that bring large groups of people into shared spaces. High-volume parts are a particular focus, he said.

The U.S. District Court for the Western District of New York announced Thursday that it would also restrict entry to people with coronavirus exposure or symptoms, including fever, cough or shortness of breath. The Southern and Eastern Districts of New York introduced similar restrictions Monday.

Officials in the Northern District of New York did not immediately respond to a question about coronavirus plans there.
