Mumps continues to circulate in US and doctors should be watchful, CDC warns

Experts says doctors should continue to test because outbreaks have occurred in vaccinated adolescents and some children

The federal Centers for Disease Control and Prevention (CDC) has warned that mumps continues to circulate in the US and that pediatricians should remain vigilant, even though spread remains low.

Mumps was nearly eliminated under routine childhood vaccinations, as part of the measles, mumps and rubella vaccine, or MMR. Most doctors have never seen a mumps case, researchers noted.
