The Monkeypox virus has been detected in the wastewater of southeast San Francisco. Records show the virus appeared in samples collected between July 26 and August 12, according to the WastewaterSCAN Dashboard, a public health surveillance tool.

Currently, it remains unclear if these detections originate from human sources. The virus is known to spread among homosexual men, who are at particular risk, and San Francisco is well-known for its large gay community.
