Nearly 200 people contracted the virus at Napier Barracks in Kent.
In April the Home Office declared the outbreak “over” and insisted asylum seekers were staying in “safe, suitable, Covid-compliant conditions”.
But last week two senior health officials said it was still “difficult to envisage” the site being considered Covid-safe.

Around 270 people were living at the barracks as of last week, the PA news agency understands.
It comes as the Home Office faces renewed calls to shut the site, which has been described as “ghettoised, detention-like accommodation”.
Napier Barracks has been used by the Home Office to house hundreds of asylum seekers since September, many of whom had crossed the English Channel aboard small boats.
