CDC assessed the risk to the United States posed by the clade I mpox outbreak in the Democratic Republic of Congo and in countries in Central and Eastern Africa. Four travel-associated cases of clade Ib mpox have been confirmed in the United States—in California, Georgia, New Hampshire, and New York. Our risk assessment remains unchanged, since onward spread of clade I mpox has not occurred in the United States to date. The risk to the general population is assessed as low.

The high proportion of children with suspected mpox reported in the current outbreak is likely due to a number of factors, including spread within and between close households, younger population demographics in impacted countries, misdiagnosis of other diseases (such as measles), poor sanitary conditions, limited access to health services, and a high level of food insecurity and malnutrition.
