University of Iowa Health Care issued a statement over the weekend to provide more context for its initial self-reporting of 64 positive COVID-19 cases. That figure represents the aggregate number of cases since February out of 15,000 employees, and does not represent a sudden spike in cases, the organization said. “The 64 number is an aggregate number that might look or feel high because it’s the first day that we’ve shared this total, however, it represents only .004% of our total employee population,” officials said. Additionally, the “overwhelming majority” of those individuals appear to have acquired COVID-19 via community transmission. “Also, per CDC guidance, symptomatic health care workers are often prioritized for COVID-19 testing. For that reason, the population tested for COVID-19 at UIHC represents a larger proportion of health care workers compared to the community population,” UIHC officials said.
