Des Moines Register Iowa has massive gaps in the data it reports on the race and ethnicity of the people who have tested positive for the coronavirus and those who have received the vaccine, Iowa Department of Public Health data shows. For weeks state health department data, as reported on coronavirus.iowa.gov, has reported double-digit percentages of race and ethnicity data as unknown or pending investigation. Public health experts warn the lack of information creates a blind spot in understanding and addressing whom the pandemic is affecting and the equity of the response. As of noon Tuesday, 35% of positive cases were reported as an unknown race and, separately, 38% of people who have tested positive have their ethnicity recorded as pending investigation, the Iowa Department of Public Health coronavirus website shows.
