当疫情得到控制后，我们可以用英语说"the outbreak has been contained"或者"the outbreak is under control".
"Contain" 在这里的意思是 "to stop something from spreading or increasing"，例如：
The government has been working hard to contain the spread of the virus.
The fire department was able to contain the fire to just one room of the house.
"Under control" 在这里的意思是 "to be managed or dealt with effectively"，例如：
The situation is now under control and there is no longer any danger.
The popce were able to bring the protest under control within an hour.
