zoo infection

兩年前德國一個動物園的北極熊都染上不尋常的病毒,其中一隻更病逝了。最近終於發現,那是一種源于斑馬的病毒。動物園是一個集合了從不同洲和棲息地的動物的地方,這樣增加了動物們互相感染病毒的風險。

is zoo a dangerous place for the animals? 2 years ago in a German zoo, their polar bears were very ill and one of them passed away. the researchers had tracked back and found out this virus is normally found in zebras.
zoo brings many animals from different continents and habitats together, so there is a much bigger chance of virus jumping to another specie.
