On February 27, 1860, powerful New York Republicans invited Lincoln to give a speech at Cooper Union, in which he argued that the Founding Fathers had little use for popular sovereignty and had repeatedly sought to restrict slavery. He insisted that morality required opposition to slavery, and rejected any "groping for some middle ground between the right and the wrong". Many in the audience thought he appeared awkward and even ugly. But Lincoln demonstrated intellectual leadership that brought him into contention. Journalist Noah Brooks reported, "No man ever before made such an impression on his first appeal to a New York audience".

On 28 February, WHO officials said that the coronavirus threat assessment at the global level will be raised from "high" to "very high," its highest level of alert and risk assessment. Mike Ryan, executive director of WHO’s health emergency program, warned in a statement that "This is a reality check for every government on the planet: Wake up. Get ready. This virus may be on its way and you need to be ready. You have a duty to your citizens, you have a duty to the world to be ready," urging that the right response measures could help the world avoid “the worst of it." Ryan further stated that the current data does not warrant public health officials to declare a global pandemic, saying that the declaration would mean "we’re essentially accepting that every human on the planet will be exposed to that virus."
