Shi Zhengli, a top virologist, said in a rare interview that speculation about her lab in Wuhan was baseless. But China’s habitual secrecy makes her claims hard to validate.

Scientists generally agree that there is still no direct evidence to support the lab leak theory. But more of them now say that the hypothesis was dismissed too hastily, without a thorough investigation, and they point to a range of unsettling questions.
...“She’s a stellar scientist — extremely careful, with a rigorous work ethic,” said Dr. Robert C. Gallo, director of the Institute of Human Virology at the University of Maryland School of Medicine.
