Mumps

As of Thursday, Iowa had 975 cases of probable, confirmed and suspected cases, said Dr. Patricia Quinlisk, the state epidemiologist.

Kansas health officials said today there are 205 confirmed and probable cases of mumps in 31 counties.

the nation's federal health agency said Wednesday it's the largest outbreak in almost two decades with more than 1,000 cases and it's expected to keep growing.

More than 800 of the cases are in Iowa.

Nebraska, which is part of an nine-state mumps epidemic, is now reporting 110 cases of the disease in 22 counties, health officials said Monday. Thirty-two of those cases are confirmed.

The state of Iowa has been experiencing a large outbreak of mumps that began in December 2005 (1). As of April 12, 2006, 605 suspect, probable and confirmed cases have been reported to the Iowa Department of Public Health (IDPH) (IDPH, unpublished data). The majority of cases are occurring among persons 18-25 years of age, many of whom are vaccinated. Additional cases of mumps, possibly linked to the Iowa outbreak, are also under investigation in eight neighboring states, including Illinois, Indiana, Kansas, Michigan, Minnesota, Missouri, Nebraska, and Wisconsin (CDC unpublished data, April 14, 2006).

More than 800 of the cases are in Iowa. The CDC has pledged to provide 25,000 doses of measles-mumps-rubella vaccine to the state from the agency's stockpile.

"On one hand, given the 800-plus cases we have, this is a serious situation," Teale said. "On the same token, we have 2.8 million people in Iowa, so the relative risk of any single visitor getting mumps is extremely low."
