Exactly how and when it fled the bat to begin its devastating flight across the globe remain open questions. In just one year, SARS-CoV-2, the virus that causes COVID-19, has infected 100 million people and killed 2 million, 400,000 of them in the U.S. Answers could stop such a calamity from happening again.Researchers in China, under government scrutiny, have been investigating since January. This week, a World Health Organization delegation of scientists from 10 different nations finally was allowed in the country to explore the virus’ origins. “This is important not just for COVID-19, but for the future of global health security and to manage emerging disease threats with pandemic potential,” Tedros Ghebreyesus, WHO’s director-general, said just after the team left for China.
