Mpox Cases by Age and Gender and Race and Ethnicity

Both age and sex or gender data were available for 99.1% of cases reported to CDC. People whose reported sex differed from their reported gender were classified as transgender. Among people for whom reported gender was not available, but sex was reported, sex was used to categorize people as men or women. While the case report form specifies sex assigned at birth, there are variations in how jurisdictions collect information on sex, and in some cases this may represent current gender identity. These case counts include those who tested positive for either monkeypox virus or orthopoxvirus (OPX) as described in the case definition.

Information on race and ethnicity was available for 94.3% of cases reported to CDC. Race and ethnicity information is often missing in reportable disease surveillance and may require contacting and interviewing the person. The Hispanic or Latino category includes people of any race, and all other categories exclude those who identify as Hispanic or Latino. Race and ethnicity was classified into the following mutually exclusive categories: American Indian or Alaska Native, Asian, Black or African American, Hispanic or Latino, Persons of Multiple Races, Native Hawaiian or Other Pacific Islander, and White. These case counts include those who tested positive for either mpox virus or orthopoxvirus (OPX), therefore classified as probable cases as described in the case definition.
