China's new virus outbreak underscores continued threat

European countries reopened borders Monday after a three-month coronavirus shutdown, although international visitors are still being kept away and there was uncertainty over whether many Europeans will quickly embrace travel outside their home countries. Reopening continued in Mexico and Brazil despite cases climbing in the two largest nations in Latin America, where authorities struggled to handle the pandemic's effect on already-weak medical systems. In the U.S., Vice President Mike Pence encouraged governors to highlight the “good news' around efforts to fight the virus despite several states reporting a rise in infections, which could intensify as people return to work and venture out during the summer. The need for constant vigilance came into sharp focus as China, where COVID-19 first emerged in December, rushed to contain an outbreak in the capital of Beijing.
