Lack of mpox transmission in a long-term care facility despite widespread exposure: Kentucky, 2023.

A certified nursing assistant at a long-term care facility worked 3 shifts while infectious with monkeypox virus providing direct care to facility residents.

We describe details of this health care-associated exposure, public health response, situational risk factors for transmission, and discuss factors that might have contributed to the lack of transmission.
