Figure 3.

Geographic distribution of cases by dialysis unit by week for the first 8 weeks of the pandemic and at the final follow-up week. Each in-center hemodialysis unit is represented by a circle. Circle size indicates the number of patients dialyzed. Circle color indicates the cumulative proportion of patients who tested positive for COVID-19 or were admitted with suspected COVID-19. Underlying green intensity reflects the number of cases in each middle layer super output area (not necessarily reflective of patients’ home locality as most, but not all, patients dialyze in their closest unit). Three units are not represented as they fall outside of the area of the map. Dates represent the first day of the week represented. MSOA, middle layer super output area.
