Mississippi, which has one of the lowest rates of vaccination among US states, is dealing with a skyrocketing level of Covid-19 patients needing hospitalization.

Data from the Mississippi Department of Health on Friday showed that out of 827 ICU beds statewide, only 107, or approximately 13%, are currently available. All 88 beds in the University of Mississippi Medical Center’s intensive care unit, the state’s largest, are full.

Hospitalizations are beginning to be seen in younger age groups, state health officer Dr. Thomas Dobbs said Thursday. He pointed to data that shows 88% of hospitalizations are among unvaccinated people, and it is having a “significant spillover effect to older, vaccinated Mississippians.”

In Texas, Austin Public Health says the region is facing the lowest-staffed ICU bed capacity since the beginning of the pandemic, with only 16 staffed beds available.
