Officials in Wayne County, Michigan, have ordered at least four portable units -- equivalent to the size of a semi-trailer -- to help increase capacity to accommodate bodies.
The county morgue has space for 300 bodies, and Wayne County Spokesman Bill Nowling told CNN each portable unit will hold about 40 bodies, increasing storage capacity to 450 total.
"Based on current projections of the number of expected cases and potential deaths, we think this will be enough," said Nowling.
"We monitor daily and will order more portable units as necessary."
Wayne County is the 13th most populous in the US and contains the city of Detroit.
Excluding Detroit there are at least 3,513 cases of coronavirus in the county, and 180 deaths, according to county data.
Michigan has at least 18,970 cases of coronavirus and 845 deaths, according to the Michigan Dept. of Health and Human Services as well as Johns Hopkins University.
