With those details, however, come new questions about how the city is calculating the numbers and whether the data is guiding sound public policy. The data also showed notable consistency in the types of activities that coronavirus patients say they partook in before they got sick. Once they have results, contact tracers in the District report that they call 99 percent of people who test positive within 24 hours. Resolve to Save Lives, a public health program that makes recommendations on coronavirus data, has praised the District for disclosing that metric. Experts say D.C. has enough contact tracers to call every patient but needs other interventions to curb the virus so that contact tracing can work, perhaps including further restrictions on indoor gatherings.
