In late March, as migrants workers started returning to Bihar, the state government imposed mandatory 14 days quarantining at government relief camps.^[21] Initially in late May, the state government created three layers of quarantining:^[22]

But within days, the government changed strategy to only have returnee migrants from category A (Block level) be mandatorily put in institutional quarantine, while the rest were sent for home quarantine if found asymptomatic.^[23] The camps were closed down on 15 June and the last registration for institutional quarantining took place on 1 June.^[24] The reason given for this was that reportedly the last batch of migrant workers came back on 1 June and the ones who came to Bihar after that aren't necessary returnee migrant workers. The other reasons was that most of these camps operated out of schools, which needed to be vacated as the government planned to reopen schools in July.^[25] As of 14 June, there were 288 Block Quarantine Camps with a total of 15,33,392 persons registered for quarantining.^[26]
