Overview

• County health authorities confirmed an adult measles case in Crestwood, marking the third Cook County case this year.
• People who visited the Aldi at 4820 Cal Sag Rd. on Sept. 24 between 5:00 and 7:30 p.m. are being notified of potential exposure.
• Officials say the adult is believed to have contracted measles from another recent local case, and contact tracing is underway.
• The previous suburban case involved a 4-year-old linked to international travel, with a public exposure window at O’Hare Terminal 5 on Sept. 11.
• Residents are advised to confirm they are up to date on MMR vaccination, as measles can linger in the air for up to two hours and has driven rising cases nationally this year.
