UPDATE: Health Officials Name New Possible Measles Exposure Sites In Kansas
Update, April 19: This story includes newly identified cases and exposure sites (previously identified exposure sites and dates that are now past the time for symptoms to develop have been removed).
Eighteen measles cases have now been identified in Johnson, Linn and Miami counties since March 8, according to the Kansas Department of Health and Environment.
In addition, the Clay County Public Health Center reported on Wednesday that a child who attends Warren Hills Elementary School in Liberty, Missouri, has been diagnosed with measles, although the center does not believe other students or staff were exposed.
Four cases have been confirmed in Kansas City, Missouri, although health officials do not believe the Kansas and Missouri cases are related.
Health departments have pinpointed where and when the individuals were infected. Because people can acquire measles anywhere from a week to three weeks after exposure, the Kansas Department of Health and Environment says there are concerns that additional cases may surface.
The agency urges people who are ill or exhibiting symptoms to remain at home unless they’re seeking medical care.
KDHE says people who visited the following locations on the dates and times listed may have been exposed to measles:

Nancy Tausz, health services division director at the Johnson County Department of Health and Environment, says the 11 locations were identified through contact tracing, the process of identifying individuals who have spent time in a room or enclosed space when an infectious individual was present or for up to two hours later. The outbreak started in a Johnson County child-care facility.
"The investigation is still ongoing," she says, and additional cases may turn up.
"They're very fluid when you do investigations, so it still remains to be seen," she says.
Except for 2014, when three cases were reported, the county had zero cases between 2012 and now. The eight cases in Johnson County already equal the total in 2011.
Initial symptoms of measles include high fever, coughing, runny nose and red, watery eyes, according to the Centers for Disease Control and Prevention. Tiny white spots typically appears inside the mouth two or three days later, followed by a rash that spreads downward on the body. The disease is highly contagious and spreads through coughing and sneezing.
The measles virus can live for up to two hours in the airspace where an infected person has coughed or sneezed, the CDC says.
Measles is preventable with the MMR (measles, mumps and rubella) vaccine. The CDC recommends that children get two doses, the first at 12 through 15 months of age and the second at 4 through 6 years of age. Two doses are 97 percent effective, according to the CDC; one dose is 93 percent effective.
