Russia Says Irkutsk Health Situation Stable After Lab Worker Dies
A 28-year-old woman who worked at a research institute in Irkutsk became very sick with pneumonia and died.
Because her workplace studies dangerous germs, people worried that she might have had plague.
Russian officials say tests did not find plague-related germs in her samples.
They also said there was no lab accident or broken safety rule.
People who had been in close contact with her were watched and tested.
The tests found some Covid-19 and rhinovirus cases, but no other infections.
Officials say the area’s health situation is stable, while monitoring continues.
The exact cause of the woman’s illness has not been confirmed.

Monitoring tests found two cases of Covid-19 and two of rhinovirus, but no other infections.
