Iowa started tracking the COVID-19 deaths of people who were diagnosed with the virus but not tested, a change that could add hundreds more deaths to the state's count. Iowa now accepts clinical diagnoses from doctors and not just positive virus tests when attributing a death to coronavirus. The change removed 433 deaths from the system but added 610, providing an initial net gain of 177 deaths and raising the state's toll to more than 2,900. Some of the removed cases could be added back in.
