Officials in the United Kingdom are delaying the country’s reopening for another four weeks to enable more people to get vaccinated amid a rise in cases linked to the Delta coronavirus variant.

In Russia, the mayor of Moscow has ordered nonessential workers to stay home this week as the city registered a six-month high in cases.

Meanwhile, in India, many areas are relaxing coronavirus restrictions, including in the capital New Delhi, as new cases drop after the devastating spring surge. Experts are warning against a premature reopening, though, as just 5% of the adult population has been fully vaccinated.
