Countries around the world scramble to contain coronavirus flare-ups as U.S. states remain open

Within the countries in question, the new flare-ups are mostly rooted in identifiable regions, where officials launched or expanded aggressive containment efforts this week. German authorities said Tuesday they would impose a new regional lockdown in a district of the country’s northwest to contain an outbreak linked to a meat-processing plant, after more than 1,500 workers were infected. Portugal cracked down on mass gatherings. Australia’s Victoria state re-shuttered several schools. An area in the northeast of Spain reintroduced restrictions. Even New Zealand, which has just 10 confirmed, active cases, tightened border measures as an increasing number of citizens abroad began to fly home.
