A 28 years old woman dies in Siberia. She works as a scientist. She works in a lab for plague diseases. People say first: The woman has the lung plague. She touches a glass with germs. Russia says later: The woman dies of a lung disease.
The state sends 200 people to quarantine. That means: These people must stay alone. They have no contact with other people. Hospitals close too. Workers clean the flat of the woman often. Experts think this is strange. They believe Russia does not tell the full truth.
The World-Health-Organization wants clear news now. A second person possibly dies. Another worker from the lab is maybe sick. The USA watches the situation closely. President Donald Trump does not believe in a bio weapon. He wants to call Wladimir Putin soon. The situation remains unclear.
