The Milwaukee Health Department says lots of families are showing up at clinics to get vaccinations against the measles.
Four people in the area, including three young children from a daycare, have been diagnosed with the highly contagious disease.
Health department spokeswoman Raquel Filmanowicz (fihl-MAHN-oh-wihtz) says there are many families at two clinics on Saturday hoping to get vaccinated. Originally the department scheduled one clinic for Saturday on the city's south side, but the department added one on the north side due to expected high demand.
Filmanowicz says no new cases have been reported so far.
She says the department is working with public and parochial schools to get messages to families encouraging them to get vaccinated.
