As of Tuesday afternoon, Suffolk County had documented 16 cases of monkeypox in total, the second-highest case count in the state outside of New York City. Across the United States there have been just shy of 3,500 cases, including about 1,000 in New York, according to the Centers for Disease Control. Dr. Gregson Pigott, Suffolk County’s health commissioner, said that even though Suffolk’s case count is relatively low, those numbers are expected to increase and the department is watching them with concern.
