The U.S. government has stopped updating some of its public COVID-19 data, as part of a “pause” to public federal health communications under President Donald Trump. While federal officials have not formally announced any details, the Centers for Disease Control and Prevention (CDC) has missed scheduled updates to some infectious disease dashboards this week. A few crucial data pages, including the agency’s wastewater surveillance dashboard, were updated despite the pause. But other missing updates and reports represent a huge blow to our ability to track COVID-19, as well as other infectious diseases.
