The U.S. death toll from the coronavirus has topped 170,000. Public health officials are expressing alarm as the number of daily COVID-19 tests across the country has dropped 17% since mid-July, making it harder for states to track the outbreak. The Centers for Disease Control is warning infection rates are “steadily increasing” in children. This comes as millions of students prepare to return to school. In Arizona, one school district outside of Phoenix has canceled classes for a week after teachers threatened to stage a sickout.

New data is coming to light about how the pandemic is disproportionately impacting people of color. According to the CDC, 14,000 pregnant people have tested positive since January. Nearly half of them have been Latinx. A new study by the University of Pennsylvania found Black and Latina women are five times more likely to be infected than white women.

Meanwhile, Time magazine reports ICE, Immigration and Customs Enforcement, is still detaining 120 children despite a court order to release them due to COVID-19 concerns.
