Data includes confirmed and probable MPX cases per CDC case definitions among SF residents reported to the San Francisco Department of Public Health.

The date in the graph and table refer to the date symptoms began, or, if not available, the earliest positive test date.

It takes time to process and confirm these data. Because of this: 

  • Case data are lagged by several days.
  • Daily case totals on previous days may increase or decrease.

All data are updated daily as more information becomes available.
