Idaho's COVID-19 7-day moving average at lowest point in 10 months; over 400K vaccinated Nicole Blanchard, The Idaho Statesman Apr. 20—Idaho's seven-day moving average for new COVID-19 cases fell to the lowest it's been since late June on Monday, and more than 400,000 Idahoans have been fully vaccinated against the disease. The Idaho Department of Health and Welfare reported 458 new cases Monday — about 152 cases per day for Saturday, Sunday and Monday. (The state no longer provides updates on weekends.) That brought the state's seven-day moving average of probable and confirmed cases down to 219.4, meaning on average over the past week, there were 219 new cases statewide each day. That's the lowest such average since June 29, when it was 214.
