Complications from a UTI??

From wiki:
On December 24, 2020, Roberts fell out of bed and could not get up, following intestinal pain and breathing difficulties that began on a hike the day before.[22] She was taken to Cedars-Sinai Hospital in Los Angeles and was later placed on a ventilator.[23][7][9] It was initially reported that Roberts died on January 3, 2021[24] after her partner, Lance O'Brien, told her manager that he had visited her in the hospital and "said goodbye".[25] O'Brien later clarified that this was an end-of-life visit; he had not been permitted to see her during her hospitalization due to the COVID-19 pandemic, but was invited to return when Roberts was taken off life support.[22] She was critically ill from a urinary tract infection that entered her organs and bloodstream, leading to a blood infection made worse due to Roberts's history of hepatitis C.[25][22] After the premature reports, O'Brien was informed by the hospital that she died in the evening of January 4, and confirmed this to the media on January 5.[25][3]
