State health officials reported three new measles cases Wednesday in an outbreak that has now sickened 24 children.
Even though the case count has doubled this week, health investigators say the outbreak's development isn't presenting them with any surprises. All of the cases involve unvaccinated Somali children from the age of 10 months to 5 years. Fifty percent of the current cases have been hospitalized.
"They all make sense based on the exposures that we were aware of and what we were watching for," said Kris Ehresmann, infectious disease director at the Minnesota Health Department.
Even so, health officials have redoubled their public health efforts.
At a meeting Wednesday night, Ehresmann said guidelines call for Somali children and all children in Hennepin County to be on an accelerated schedule for the measles-mumps-rubella (MMR) vaccine, with 28 days between the required two dosages.
She said the last large outbreak in Minnesota was in 1990, when 460 cases were reported and three people died.
"We want to make sure that we are increasing that wall of protection in the community," Ehresmann said.
She was among speakers at the Cedar-Riverside People's Center to brainstorm among health professionals and Somali leaders about how best to increase vaccination rates and inform the community.
