Again, because of the extreme secrecy and lack of access imposed on the region, it's difficult to know for sure. However, there are reports from Uighurs and advocates expressing great concern about the fact that even as China was closing many public institutions in order to prevent the spread of the coronavirus, the concentration camps were not being closed. People were still being sent to labour camps, where they were obviously at great risk of exposure to coronavirus.
That indicates, at the very least, a great lack of concern for the protection of Uighur life. At worst, it cynically indicates a use of the coronavirus pandemic in order to effect pre-existing goals of eradication.
