Three Jewish day schools in New York were closed on Tuesday after a Jewish man in his 50s was taken to hospital suffering from coronavirus.
New York Mayor Bill de Blasio said the patient was “in a serious condition”.
The schools, one of which was attended by one of the man’s sons, were closed for the day as a precaution.
According to Yeshiva World News, the son had no symptoms, but his brother, a student at New York’s Yeshiva University, has been showing symptoms associated with the illness.
