California health authorities announced Friday that a second individual has caught monkeypox as a result of close contact with the state's first case, according to a report by CalMatters.org.
In Sacramento County, California, the first case of monkeypox was recorded on Tuesday.
The first person recently returned from a vacation to Europe, where there have been recent reports of clusters of infections. Officials did not provide the date the person returned from their vacation, nor did they provide any demographic information. Contact tracing was used to identify the second person.
Both persons are isolated in their houses, according to Sacramento County Public Health Officer Dr. Olivia Kasirye.
"The general population is not at risk," Kasirye told CalMatters.org.
