The rapid spread of the delta coronavirus variant has forced a growing number of countries to reimpose lockdowns and other public health restrictions, raising fears that the more contagious variant was hampering global efforts to contain the pandemic.

The United States is providing Honduras with 1.5 million doses of the Moderna coronavirus vaccine, Secretary of State Antony Blinken tweeted Sunday. Health experts have warned that the delta variant — which was first identified in India — is on track to become the most dominant version of the coronavirus worldwide. Ahead of England’s plan to ease remaining coronavirus restrictions on July 19, the delta variant has continued to spread, and is now responsible for more than 90 percent of new infections in Britain.
