Daria Shipilova, a 28-year-old lab technician at Russia’s Anti-Plague Institute in Irkutsk Oblast, died of pneumonia of unknown origin after being hospitalized for two days and placed on a ventilator. Following her death, public health officials quarantined nearly 200 people who had close contact with Shipilova. The Russian government agency Rospotrebnadzor investigated the case, ruling out any connection to plague or other dangerous pathogens from her work. Despite initial fears of an outbreak, testing showed only two cases of COVID-19 and two cases of rhinovirus among those quarantined, leading officials to declare stability in the sanitary situation by early next week.
