Israel on Friday is to become the first developed country to impose a second nationwide lockdown, as its government struggles to contain a fresh coronavirus outbreak that has hammered the economy and divided the nation. The lockdown, which will last at least through early October, aims to prevent mass gatherings during the Jewish holidays that begin at sundown Friday. It will extend through Rosh Hashana, Yom Kippur and Sukkot—holidays that typically involve millions of Jewish worshipers attending synagogues and gathering for prayer services. If deemed effective, Israel will later move to localized lockdowns of coronavirus hot spots. (Schwartz and Lieber, 9/13)

Austria is seeing the start of a “second wave” of coronavirus infections, the country’s leader said Sunday, urging citizens to comply with reinforced rules to keep down new cases and suggesting that companies keep employees working from home if possible. Austria had a relatively successful first phase of the pandemic but has joined other European countries in seeing a rise in infections in recent weeks. It recorded 869 new infections on Friday, the highest daily figure since late March. Chancellor Sebastian Kurz announced that day that the government would reimpose measures such as mandatory mask-wearing in shops. (9/13)

Covid-19 has killed more than 130,000 in Brazil, second only to the U.S., and hammered the economy.

For many countries, battling the coronavirus has been a sprint to bring infections under control, then a struggle to keep it that way. In India, it has turned out to be a marathon. No one knows that better than Dr. Santhosh Kumar, a 48-year-old infectious disease specialist who treated some of the country’s first infections back in February. He is still fighting the virus, these days building a 10,000-strong corps of health-care workers and volunteers in southern India to tackle yet another wave of infections. (Agarwal, 9/13)
