é luó sī俄罗斯bù míng不明fèi yán肺炎shì jiàn事件yǐn qǐ引起fáng yì防疫guān zhù关注
At a Russian institution that studies infectious diseases, a staff member died of severe pneumonia.
Because she may have come into contact with dangerous pathogens, some people worry that this incident is related to plague.
However, Russian authorities tested the deceased person and close contacts. They found no pathogens such as plague, and no laboratory safety incident was found.
The true cause of death is still unclear, but the World Health Organization said there is no evidence that the disease is spreading and does not recommend restrictions on travel or trade.
Hulunbuir in Inner Mongolia once issued a plague risk notice, but later removed it to avoid public misunderstanding.
Local authorities said there is currently no plague outbreak, and the possibility of an outbreak is also low.
Hong Kong and Macao have strengthened temperature checks for arriving travelers and asked people who recently visited relevant areas of Russia to report their travel history.
Plague is often spread by infected fleas or animals, and pneumonic plague may also spread from person to person.
Plague can now be treated with medicine, but it is still very important to seek medical care promptly after symptoms appear.
