Health officials are treating a presumptive positive case of monkeypox found in the specimen of a patient in New York City, according to the NYC Department of Health.

Specimens from two patients in New York City were tested for possible monkeypox.

The New York City Department of Health and Mental Hygiene ruled out one case, and the other has been identified as a Orthopoxvirus, the family of viruses to which monkeypox belongs.

Confirmation for monkeypox is pending testing from the Centers for Disease and Control Prevention.

That patient is isolating as health officials are treating their case as a presumptive positive until confirmed.

The NYC Health Department is also carrying out contact tracing.
