Good morning. We’re covering how Xi Jinping sees China’s tech future, why investors are betting on K-pop fans and whether reinfection is really something to worry about. | | By Melina Delkic | | BTS at the Golden Disk Awards in Seoul in January. Ahn Young-Joon/Associated Press | | Shares in Big Hit Entertainment, the management company behind the K-pop group, begin trading in South Korea today. The country’s most hotly anticipated initial public offering since 2017 has investors scrambling, with hundreds of pre-orders for every share. | | What investors are really paying for may not be BTS or its management company, but its ecosystem of followers. BTS fans are known as some of the most devoted in music. Beyond attending concerts, they enthusiastically perform services for the band that range from translating BTS content to running highly coordinated social media campaigns. | | The fan base, which calls itself the Army, is diverse, cutting across lines of gender, age, religion and nationality. But investors remain concerned about the company’s dependence on BTS, as boy bands usually have short life spans. | | Details: Big Hit reported a profit of $86 million last year, and is valued at around $4 billion, after raising more than $800 million by offering investors about 20 percent of the company. BTS was the world’s most lucrative touring act last year and, by one estimate, adds more than $3.5 billion annually to South Korea’s economy. | | Bussa Krishna in prayer before a statue of President Trump at his home in February.

When Mr. Trump tested positive for the coronavirus, Mr. Krishna, a farmer in his 30s, fell into a deep depression and began to starve himself. | | Many Indians in major cities dislike Mr. Trump, but he enjoys broad support. A survey in February found that 56 percent believed that Mr. Trump would “do the right thing when it comes to world affairs.” Many see Mr. Trump’s “America First” stance as mirroring how Prime Minister Narendra Modi projects himself to his own supporters. | | In other virus developments: | | President Xi Jinping in Shenzhen on Wednesday. Ju Peng/Xinhua, via Associated Press | | When China first opened to overseas investors, the country was desperate for foreign technology. Now, as China faces global barriers, its leader, Xi Jinping, is urging greater domestic innovation. | | Mr. Xi delivered this message on Wednesday in the southern city of Shenzhen. It was symbolic: Since its designation in 1980 as a “special economic zone,” Shenzhen has been the incubator for reform and opening up. Now Mr. Xi hopes that Shenzhen can be an important high-tech hub and that he can shift the balance by taking Chinese tech, investment and power out into the world. | | Mr. Xi said China would still welcome foreign investment, but he also said its citizens needed to prepare for an increase in global tensions. “The world has entered a period of turbulence and transformation,” he said. | | Quotable: “A lot is riding on this for Shenzhen to be able to set an example for other cities in China,” said a professor at the University of Hong Kong. “Shenzhen’s importance to the national psyche is far greater than just its economic importance.” | | Daniel Berehulak for The New York Times | | Farmers in Mexico armed with sticks, rocks and homemade shields ambushed soldiers and seized La Boquilla Dam, above, to stop water payments to the United States. The farmers said the Mexican government was sending water — their water — to Texas, leaving them next to nothing for their crops. | | Our reporter looked at the standoff pitting Mexican farmers against their country’s president and the global superpower next door. The fight illustrates growing conflict over increasingly scarce resources as a result of rising temperatures and long droughts, which have been caused by climate change. | | PAID POST: A MESSAGE FROM CAMPAIGN MONITOR | TEST: Email Marketing 101: Never Sacrifice Beauty for Simplicity | A drag-and-drop email builder, a gallery of templates and turnkey designs, personalized customer journeys, and engagement segments.

But these cases are very, very rare. Here’s what you need to know. | | Coronavirus reinfection is unusual. Since the first confirmed case of reinfection was reported in Hong Kong on Aug. 24, there have been three published case studies and reports of another 20 await scientific review. | | People in line to get tested in Brooklyn, N.Y. Spencer Platt/Getty Images | | In most people, the immune system works as expected. Reinfections can occur for any number of reasons: because the initial infection was too mild to produce an immune response, for example, or because the immune system was compromised by other health conditions. On occasion, a patient may be exposed to a large amount of virus that seeded an infection before the immune response could take effect. | | This variability is entirely expected, and it has been observed in patients with diseases like measles and malaria, experts said. | | A resurgence of symptoms doesn’t prove reinfection. For every confirmed case of reinfection, there are dozens of anecdotal reports of infected people who were sick and seemingly recovered but then became ill again weeks to months later. Usually there are crucial data missing in those cases, like a confirmed lab diagnosis, or a virus sample that can be sequenced. A vast majority of these cases are unlikely to be true infections. More likely, these are people experiencing a resurgence of symptoms connected to the original infection. | | That’s it for this briefing.
