Covid-19 global updates: U.S. warns against travel to Britain as coronavirus cases surge, restrictions lift

Here are some significant developments:

• Canada said it will begin to ease pandemic restrictions at the U.S.-Canada border beginning Aug. 9, allowing U.S. citizens and permanent residents who are fully vaccinated to enter for nonessential travel without quarantining.
• Global stock markets swooned Monday with the Dow tumbling more than 700 points. It was its worst one-day decline of 2021, as investors grow increasingly anxious about a delta variant-led resurgence in coronavirus cases and its potential to derail the economic recovery.
• The coronavirus pandemic may have caused more than 4 million excess deaths in India, according to an estimate from the Washington-based Center for Global Development. India’s official covid-19 death toll stands at 414,000, a number experts believe is a vast undercount.
• Russia’s total number of confirmed coronavirus cases topped 6 million Tuesday, the state-owned Tass news agency reported. Russia is suffering a spike in new infections and deaths as vaccinations lag behind.
• A close confidant of deposed Myanmar leader Aung San Suu Kyi died in prison Tuesday after contracting covid-19, Agence France-Presse reported, quoting the country’s military authorities. The 78-year-old Nyan Win was a senior member of Suu Kyi’s National League for Democracy.
• Muslims around the world Tuesday were observing a second Eid al-Adha, or Feast of the Sacrifice, in the shadow of the coronavirus pandemic. The celebration is normally marked by large gatherings and communal prayers — but authorities in some countries have restricted travel or appealed to worshipers to stay home to avoid spreading the virus.
