Sewage Examination to Identify B.1.617.2 Hotspots: In an extraordinary new move, British authorities have used tests on sewage to identify areas where the B.1.617.2 Covid strain has been spreading more rapidly. Based on those tests, Leicester city, about 100 miles north of London, and Hounslow suburb in London next to Heathrow have been identified among the areas where heavy new surge testing and jabs have been ordered. Both Leicester and Hounslow have a substantial Indian population. The areas were identified also on the basis of travel patterns, and recent travel from India to these areas is now being investigated. But the sewage examination points to evidence of Covid prevalence in human waste output.
Strain Emerging from India Not Too Deadly: Britain has now reported almost 3,000 cases of the B.1.617.2 variant that was first found in India. The numbers are growing steadily, but not wildly. Also, not lethally. On Wednesday, Britain recorded 2,967 cases of this strain but reported only three new deaths. That differential arises presumably because by now more than 20 million people have been given a double dose of the vaccine. “We have increasing confidence vaccines are effective against all variants, including the Indian variant,” Prime Minister Boris Johnson told Parliament.
