The rollout of rapid testing is being supported by a £149 million grant.
Care home staff in England will receive two rapid-result tests a week in addition to regular testing to help keep the new coronavirus variant at bay.
Health officials have brought forward plans for care home staff to receive bi-weekly lateral flow device tests (LFDs) as concerns grow about the rapidly spreading strain.
Staff in all tiers will be given two LFDs, one mid-week, in addition to the weekly PCR tests, according to the Department of Health and Social Care.
If a case of coronavirus is identified in a care home in a Tier 4 area, all staff members will be tested daily with LFDs for a week.
Public Health England have confirmed that LFDs can detect the new variant.
