He added that the federal government is "closely monitoring" emerging cases and had declared a public health emergency as a "precautionary tool to ensure that we have the resources we need at our disposal to respond quickly and effectively."
The president said he is receiving regular briefings on the outbreak, and that Homeland Security Secretary Janet Napolitano will provide regular updates
to the public.
Obama made his remarks during a speech to the National Academy of Sciences.
WASHINGTON (CNN) - An average of the most recent national polls indicates that two out of three Americans approve of the job Barack Obama's doing as president.
According to a CNN Poll of Polls compiled Sunday, 66 percent say they approve of how Obama's handling his duties as president. Twenty-seven percent disapprove. The 66 percent figure is up two points from CNN's previous Poll of Polls, which was compiled late last week.
The president's approval rating stood at 64 percent in a CNN poll of polls in January, just after his inauguration.
"Most polls have shown Obama getting fairly high marks on most of the issues he has handled so far," says CNN Polling Director Keating Holland. "One exception has been the way he has handled government assistance to failing banks and automakers. His numbers on the federal deficit are also low in comparison to his approval ratings on the economy and foreign policy."
So how does Obama compare to his predecessors in the White House around the first 100 days mark?
Editor's note: How would you rate the new Congress in President Obama's first 100 days? You'll get a chance to make your opinion known on at 7 p.m. ET Wednesday on the CNN National Report Card.
WASHINGTON (CNN) - There's little debate that Democrats who run Congress mark President Obama's 100-day milestone with some significant victories.
First and foremost, they passed the president's $787 billion measure intended to stimulate the economy with warp speed, meeting his February deadline.
Congressional Democrats also made good on promises to push through several priorities that President Bush had refused to sign into law.
They finally approved last year's bill to fund the government, with significant increases in spending for things such as education, health care and transportation.
And Democrats passed long stalled legislation for children's health insurance - the State Children's Health Insurance Program, known as S-CHIP - as well as the Lilly Ledbetter Fair Pay Act mandating equal pay for women in the workplace.
But the slew of legislative achievements during Obama's first 100 days have come at the cost of bipartisanship.

(CNN) - Our executive producer said it all, "All those people who told me that news never happens on Sunday mornings are out of their minds." Yes, there was plenty of criticism and controversy on the Sunday talk shows - and a fair amount of news was made - but the most important story broke after the usual pundits and politicians had had their say.
(CNN) - The United Auto Workers union announced Sunday it had reached an agreement with Chrysler, Fiat and the U.S. government that meets the requirements of the Treasury Department for loans to the auto giant.
In a statement, the UAW said the deal was still subject to ratification by union members at Chrysler.
The "painful" concessionary agreement, the UAW said, "includes modifications to the union's 2007 collective bargaining agreement and the Voluntary Employee Beneficiary Association (VEBA) trust."
Union members must approve the deal by Wednesday, the statement said.
WASHINGTON (CNN) - An independent commission is needed to determine who authorized the use of abusive interrogation techniques against suspected terrorists, a leading advocate of such a panel said Sunday.
"I want to know who was it who made the decisions that we will violate our own laws; we'll violate our own treaties; we will even violate our own Constitution," Sen. Patrick Leahy told CBS' "Face the Nation."
"That we don't know," said Leahy, D-Vermont, the chairman of the Senate Judiciary Committee. "We don't know what that chain of command was."
Former President George Bush repeatedly denied that his administration authorized the torture of prisoners in U.S. custody. But a set of legal opinions released earlier in this month documented the Bush administration's justification for coercive interrogation techniques including waterboarding, which has been considered torture since the Spanish Inquisition.
A Senate Armed Services Committee report released last week showed that top Bush administration officials gave the CIA approval to use waterboarding as early as 2002. And in 2003, a meeting that included then-Vice President Dick Cheney, CIA Director George Tenet, Attorney General John Ashcroft and National Security Adviser Condoleezza Rice reaffirmed the use of coercive tactics, according to the Senate Intelligence Committee.
The releases have fueled calls for investigations of former administration and led to arguments from Bush's defenders - including Cheney - that the tactics produced information that saved American lives.
Leahy first proposed the idea of a nonpartisan "commission of inquiry" in March. He said Sunday that he was not "out for some kind of vengeance," but added, "I'd like to read the page before we turn it."

WASHINGTON/POLITICAL For the latest political news: www.CNNPolitics.com.
As introductions go, it has been a fast-paced, fascinating first 100 days: an ambitious domestic agenda aimed at reinvigorating the economy and the government's reach into its workings, and several provocative steps on the world stage that, like at home, signal a clear break from the previous administration.
It's early April, and President Obama is on his way to France with the nation's top diplomat at his side. As he and Secretary of State Hillary Clinton converse in a private room aboard Air Force One, a photographer peers through the half-open door and snaps a candid picture of the formerly bitter campaign rivals.
President Barack Obama's decision to release four Bush-era memos regarding the use of so-called "enhanced interrogation techniques" was heavily criticized Sunday as a couple of prominent senators told CNN's John King that the decision was a potentially dangerous mistake.
Reporters are outshining the Obama administration in the first hundred days, at least according to the administration's press liaison.
An independent commission is needed to determine who authorized the use of abusive interrogation techniques against suspected terrorists, a leading advocate of such a panel said Sunday.
Obama administration officials, alarmed at doctor shortages, are looking for ways to increase the supply of physicians to meet the needs of an aging population and millions of uninsured people who would gain coverage under legislation championed by the president.
White House Press Secretary Robert Gibbs told reporters that President Obama had shown no flu symptoms since returning from Mexico, where he stopped April 16-17 on his way to a regional economic summit.
