The Centers for Disease Control and Prevention (CDC) issued updated guidance last week for people to wear masks indoors in public areas, regardless of vaccination status, where community spread is substantial or high. The CDC’s map uses different measures to determine the rate of transmission than measures the Idaho’s COVID-19 Dashboard depicts. Idaho’s dashboard is maintained by the Division of Public Health in the Department of Health and Welfare.
We strongly encourage everyone to follow the CDC guidance and wear a mask indoors in public areas where the rate of transmission is substantial or high. The only way we’ll beat the virus that causes COVID-19 is by limiting its ability to spread and mutate yet again into another variant of public health concern. We’re in a race against the virus, and vaccination is still the best protection against serious illness, hospitalization, and even death from COVID-19. But the Delta variant is a worthy foe and vaccination rates aren’t high enough to keep it in check. So wearing a mask is important again.
But we also understand how confusing it is that the data on the CDC’s site and on Idaho’s dashboard don’t match, and we’d like to explain why that is.
The CDC is using case rates or molecular testing percent positivity to calculate the community rate of COVID-19 transmission. Here are explanations for why the data are different on both sites.
