Maps and charts: Coronavirus and COVID vaccines in Iowa

These maps and charts reflect data from the Iowa Department of Public Health and the U.S. Department of Health and Human Services.

The Gazette, in partnership with the Iowa Newspaper Association and other Iowa papers, launched iowacoviddata.com on Feb. 24, 2022, collecting data from IDPH and HHS. The site provides data previously shared on the state’s coronavirus site that was decommissioned on Feb. 16, 2022, when the state’s COVID-19 disaster declaration expired.

Iowa's first positive COVID-19 cases were publicly identified on March 8, 2020, after three Johnson County residents who had been on a cruise ship in Egypt tested positive for the virus.

Linn County outpaced the state in coronavirus cases between March 30 and April 22, 2020, with outbreaks in Iowa's long-term care facilities being a primary area of concern. As March ended, one-third of Linn County's 90 cases were tied to Heritage Specialty Care in Cedar Rapids. Fourteen residents there had died by April 11, when Iowa's death toll had reached 34. More than 100 Iowans had died from COVID-19 by April 24 and 1,000 by Aug. 18. Over 2,000 Iowans were reported dead by Nov. 17. 2020; 5,000 by Feb. 4, 2021; and over 8,000 by Jan. 5, 2022.

The state changed to reporting on tests and not individuals on Feb. 19, 2021, though the individual cases can still be found on this page.
