Health officials in the Las Vegas area and Cincinnati have issued warnings about potential measles exposures in public locations linked to sick visitors from out of state, part of an ongoing rise in measles activity in the United States.
Meanwhile, two more cases have been reported in Chicago's suburbs.
Las Vegas patient visited several area locations
The Southern Nevada Health District reported a confirmed infection in someone who visited Clark County between April 1 and April 6.
The person stayed at the MGM Grand hotel and spent time at several of the facility's attractions. Health officials said the patient also visited locations throughout Las Vegas and Henderson.
"People who may have been exposed should review their immunization status and contact their health care providers if they are not fully immunized against measles or have not already had the disease," the officials said.
Cincinnati's second case involving a visitor
The Cincinnati Department of Health warned of potential measles exposures at a hotel and restaurant downtown after a visitor from Illinois tested positive for measles, the Cincinnati Enquirer reported, citing local health officials.
The case is the city's second involving a sick visitor this year.
Two more cases in Chicago suburbs
In other developments, two more cases were reported in the suburbs of Chicago, and neither were linked to an outbreak at a Chicago migrant shelter.
One of the cases marks Cook County's second case of the year, which involves an adult who has a community-acquired infection. The individual had spent several hours across several days while infectious at a Hispanic supermarket in Cicero, the county's health department said in a statement.
The second patient is from DuPage County, and the county health department said the case marks the county's first since 2009. The patient received outpatient care, and health officials are tracking people who may have been exposed. So far, no exposure locations have been identified in DuPage County.
In its latest update, the Centers for Disease Control and Prevention confirmed 121 US measles cases so far for 2024. That total does not include the latest from the Chicago area.
