In early February 2024, we will be retiring the Mpox Case Summary dataset. This dataset will be archived and no longer update. A historic record of this data will remain available.

A. SUMMARY This dataset represents probable and confirmed mpox cases per CDC case definitions among San Francisco residents reported to the San Francisco Department of Public Health. Data are lagged by 4 days, based on the most recent date a case is received by the source system.

B. HOW THE DATASET IS CREATED Case information is based on confirmed or probable positive laboratory tests reported to the San Francisco Department of Public Health. Processes to provide quality assurance and other data verification are completed before the data are reported.

These data may not be immediately available for recently reported cases because of the time needed to process tests and validate cases. Data are continually updated to maximize completeness of information and reporting on San Francisco residents with confirmed or probable mpox.

To ensure data privacy, we suppress data when cumulative counts are between 1-4. The exception to this rule is for the response option “Unknown” which does not provide any identifying information. If only one response option has a count <5 we also suppress the response option with the second lowest count (including “Unknown” or a response option with a count of 0). If the second lowest response option is 0, both response options will display “<5”. If the second lowest response option is a number greater than 0 both response options will display “< [sum of two lowest counts]”.

Data notes for population characteristic types are listed below.

Race/ethnicity * The response option "Other" is categorized by the source system, and the response option "Unknown" refers to a lack of data.

Gender * The response option "Other" is categorized by the source system, and the response option "Unknown" refers to a lack of data.

Sexual orientation * The response option "Other" is categorized by the source system, and the response option "Unknown/Declined" refers to a lack of data or those who did not disclose their sexual orientation. * The response option “Gay, Lesbian, or Same-Gender Loving” is a standard reporting option and cannot be split into individual categories. This is a limitation of the data from the source system.

Sexual contact during incubation period * We track whether mpox cases had sexual contact during the 21 days prior to symptom(s) onset. This timeframe is the incubation period. * The response option "Unknown/Declined" refers to a lack of data or those who did not disclose their sexual contact history.

For convenience, we provide the 2020 5-year American Community Survey population estimates.

C. UPDATE PROCESS Updates to the data are made through automated and manual processes Monday through Friday.

D. HOW TO USE THIS DATASET This dataset shows total cases (probable and confirmed) by population characteristics. Filter the “characteristic_type” column to explore a topic area. Then, the “characteristic_group” column shows each group or category within that topic area and the total count of cases identified within that population subgroup.

E. CHANGE LOG 1/4/2023: Due to low case numbers, this page will no longer include cases after 12/31/2022.
