The mouse infected with a lab-created type of SARS coronavirus was squirming upside down, dangling by its tail as a scientist carried it to a weighing container one day in February 2016. But the mundane task turned dangerous in seconds inside the North Carolina laboratory, which has drawn scrutiny for its partnership on similar research with China’s Wuhan Institute of Virology.
In that moment, it wasn’t enough that the experiment was taking place inside a biosafety level 3 lab, the second-highest security level, which was layered in high-tech equipment designed to keep dangerous pathogens from escaping. Or that the scientist was covered head-to-toe in gear to protect against infection: a full-body Tyvek suit, boot covers and double gloves, plus a powered air-purifying respirator.
As she carried the mouse, it climbed up its tail and bit her hard, breaking through the gloves and plunging its teeth — and potentially the virus — into her ring finger.
