CDC says mumps outbreak continues in N.Y.

The Center for Disease Control has issued a preliminary set of data regarding mumps cases for 2010 in the United States.

The data is the latest available, however, the figures are unofficial and will not be certified by the public health officials of various states or the CDC until next year, the Rochester Infectious Disease Examiner reports.

The data provided covers the first 25 weeks of 2010, through June 26.

According to the data, New York City’s mumps outbreak continues, though the number of new mumps cases in upstate New York and New Jersey appears to have declined. Preliminary numbers indicate that New York City has reported 927 cases of mumps in 2010 through June 26.

Upstate New York has reported 644 cases, with an additional 257 reported in New Jersey, the Rochester Infectious Disease Examiner reports.

The CDC has had reports of 2,106 cases of mumps nationwide, with 87 percent of those from New York and New Jersey.

Mumps is preventable with the MMR vaccination.

“Mumps vaccine, which is included in the combination measles-mumps-rubella and measles-mumps-rubella-varicella vaccines, is the best way to prevent mumps," the CDC told the Rochester Infectious Disease Examiner. "Mumps vaccine effectiveness has been estimated at 62 to 91 percent for one dose and 76 to 95 percent for two doses.”
