PARMA, Ohio — The Cuyahoga County Board of Health on Friday released the number of coronavirus cases by ZIP code, giving county residents the first glimpse of infections in their parts of the county.

Prior to Friday, only countywide data, and data for the city of Cleveland, was available.

Friday’s release of the breakdown of cases by geography caps a week of growing demand from Cuyahoga County residents for more detailed information from the Board of Health about the spread of coronavirus in their communities.

Cleveland.com in its reporting, through its editorial board, and on its weekly podcast, This Week in the CLE, pressed the Board of Health for information about the individual cities affected by the coronavirus, and the board’s decision to keep secret demographic data about those dying from coronavirus.

Numbers shown on the map represent the ZIP codes in which patients with lab-confirmed cases of coronavirus live, not the area where they were tested, according to a board spokesman.

The map’s data shows confirmed cases as of 6 a.m. on March 26, but more cases have been confirmed since then, board Medical Director Dr. Heidi Gullett said Friday. As of Thursday, the state reported 259 cases total in Cuyahoga County.

The map shows that the highest quantity of coronavirus cases, with 10-16 individuals infected, is in the following zip codes:

•44133, which includes North Royalton

•44022, which includes Chagrin Falls, Moreland Hills, Hunting Valley and Bentleyville

•44124, which includes Mayfield Heights, Lyndhurst and Pepper Pike

•44121, which includes South Euclid and parts of Cleveland Heights

•44118, which includes parts of Cleveland Heights, East Cleveland, Shaker Heights, South Euclid and University Heights

The board intends to provide updated maps showing cases by zip code every Friday.
