Britain Battles Mutant Coronavirus Outbreak Henry Ridgwell LONDON - Britain launched an emergency program of door-to-door testing in several areas Tuesday following the discovery of hundreds of cases of the coronavirus variant, first identified in South Africa, which scientists say could be more resistant to vaccines. Mobile testing units were deployed to several regions, including parts of central and suburban London, while firefighter units and volunteers helped to deliver home testing kits and administer door-to-door testing. Local authorities aimed to conduct 80,000 coronavirus tests. By Tuesday morning, 105 cases of the mutation first seen in South Africa were identified in eight districts across Britain. Eleven of those cases did not have any direct link to international travel, suggesting the variant is being transmitted within the community. .
