Precautions in place in several hospitals in eastern Russia amid uncertainty over death of Darya Shipilova

Several hospitals in Siberia have been placed under quarantine after the death of a woman who worked at an anti-plague institute.

Darya Shipilova, an employee at an institute in the eastern city of Irkutsk, died on the night of 2 October at a regional hospital in the nearby town of Shelekhov two days after falling ill.

It remains unclear how she became unwell. Unconfirmed reports circulating in Russian media have suggested Shipilova, who was in her late twenties, may have been infected at work after an accident at the laboratory. Officials have not publicly confirmed that account.
