WEST DES MOINES, Iowa (AP) — Authorities say a suburban Des Moines educator has died from complications of COVID-19, but it’s unclear if she contracted the virus at school or elsewhere. Shane Christensen, the principal of Indian Hills Junior High School, says special education assistant Jennifer Crawford, died Monday. The school is in West Des Moines.

Iowa has the fourth-highest coronavirus positivity rate in the nation. Only 10 of Iowa’s 99 counties are below the 5% threshold at which public health experts recommend measures to slow the spread of the virus, including mandatory masks and limits on gatherings.
