Monkeypox clusters have been reported in other countries that normally do not report monkeypox, including Europe and elsewhere in North America. At this time, it is not clear how people in these clusters were exposed to monkeypox. The current monkeypox situation is constantly evolving and subject to change.


On May 17, 2022, a report states that the Massachusetts Department of Public Health and the Centers for Disease Control and Prevention (CDC) are investigating a confirmed case of monkeypox in the United States.


On May 27, 2022, the California Department of Public Health (CDPH) reported one confirmed case of monkeypox.

San Diego

On June 15, 2022, the County of San Diego (County) Health and Human Services Agency reported two probable cases of monkeypox in San Diego County. 


Number of Confirmed and Probable Cases


Date as of July 1, 2022 at 3:50 pm

NOTE: A confirmed case has tested positive specifically for monkeypox virus. A probable case has tested positive for orthopox virus with no suspicion of other recent orthopox exposure and is pending confirmatory testing.

The County first issued a health advisory on May 23, 2022, following monkeypox cases that have occurred in the United States. These cases were mostly related to international travel or importation of animals and remain very rare. Information will be updated weekly. 

The County issued an additional health advisory on June 10, 2022, for healthcare providers to maintain a high index of suspicion for monkeypox in persons presenting with exposure and a history of rash. The current monkeypox situation is constantly evolving and subject to change.

The  CDPH is closely monitoring monkeypox transmission in the U.S. and California to ensure rapid identification of cases.  The risk of monkeypox to the public is currently very low based on the information available.
