GRIMES, Iowa (AP) — Iowa school officials have released guidelines that allow schools to reopen to normal activities as of July 1 without health checks before entering the building, no required face coverings and no required social distancing. A spokeswoman for the Iowa State Education Association, the state’s teacher’s union, says the plan doesn’t comply with CDC guidelines for public places and is an “obscene” gamble on the health of students, teachers and other school employees. An education department spokeswoman says the guidance was created with the Iowa Department of Public Health and schools may require their own stricter measures after consulting with a lawyer and local public health officials.

Zach Wahls and Rep. Dave Jacoby, both Coralville Democrats, said that they traveled separately to Cedar Rapids to get tested through TestIowa, the $26 million program touted by Gov. Kim Reynolds.Both wanted to make sure they were virus-free after interacting with colleagues and the public during the session.Both lawmakers’ samples were taken on different days last week.

DES MOINES, Iowa (AP) — Two high school baseball games scheduled for Thursday at Principal Park in Des Moines were not held after officials said a ballpark staff member tested positive for coronavirus. Officials with the park, which is home to the Triple-A minor league Iowa Cubs, say all staff at the ballpark will now undergo testing for COVID-19. Ankeny Christian and Orient Macksburg, as well as Indianola and Gilbert, had been scheduled to play at the park. When it resumed high school baseball games earlier this month, Iowa became the first state in the nation to bring back high school athletics in the wake of the coronavirus pandemic.
