(Bloomberg) -- An unprecedented 70% of intensive care unit patients have Covid-19 at a hospital network in Idaho, a state where vaccination rates are low, medical care is being rationed and virus hospitalizations are setting records.

The Covid-19 ICU mortality rate is up to 43% at St. Luke’s health system, higher than the prior peak, and 98% of ICU patients suffering the deadly malady are unvaccinated, James Souza, chief physician executive of the statewide network of six hospitals, told an online news briefing.
