A retrospective study identified 2 children and 23 adult ILI cases associated with COVID-19 from the Seattle Flu pandemic surveillance platform [10]. We estimate that there were a total of 6748 [95% CrI: 4133, 11,020] (2268 [95% CrI: 498, 6069] and 4367 [95% CrI: 2776, 6526] for people under and over 18 years, respectively) cases of COVID-19 cases during that 15-day period across the 22 PUMAs of Seattle, ranging from 231 cases [95% CrI:199,265] in PUMA 11,614 to 410 cases [95% CrI:364,459] in PUMA 11,601 (Table S2).
