The Centers for Diseases Control and Protection is taking all necessary steps to respond to an Ebola outbreak in the United States, the agency said Monday.

The agency said it is planning to quarantine all of its employees and contractors in the US.

Agency officials told CBS News that they have not yet issued a travel alert for people living in the U.S. They said they will release a more detailed statement later.

“We are taking all appropriate steps to protect the health and safety of all employees and others,” CDC Director Tom Frieden said in a statement.

The statement came just hours after a second CDC official, Dr. David Nabarro, said the agency was taking “a precautionary approach” to a possible Ebola outbreak.

Nabarro made the comments after a meeting with President Donald Trump.

He said he spoke with Trump by phone to reassure him of CDC’s preparedness to deal with an Ebola crisis.

The CDC is planning a major public health exercise next week, including a conference call with top health care professionals from more than 30 countries.

The exercise will include an open call with U.N. Secretary-General Antonio Guterres, who will lead the effort.

“The U.K., Germany, France, Italy and the Netherlands are among those participating,” the CDC said in the statement.

“Each country is responsible for a specific number of workers, so we are looking at the numbers, including those in the USA and the UK, who are expected to be working in a particular country.”

The U.A.E., a European Union member, and Brazil are among the nations that have already been notified about the CDC exercise.

The U to K in Germany, which has already been visited by CDC workers and is expected to receive a full quarantine, is one of the locations in Germany that is expected in the coming days, the CDC added.

The White House has also confirmed that the CDC will be hosting a briefing on the Ebola virus at the White House on Tuesday.

Trump also praised Nabarro’s comments and said that “everyone is doing their job.”

“Our country is very strong and it’s strong and will be strong,” Trump said Monday, adding that “the world is watching.”

But, he also noted that the virus was still “a big deal.”

“It’s very, very scary,” Trump added.

“But it’s going to get much worse.”

The CDC said the CDC is in the process of conducting a “massive exercise” to train U.C.L.A.’s infectious disease team on how to respond in the event of an Ebola pandemic.

The United States is not yet considered to be at a “high risk” level, which means the U, as the only country not currently taking in any Americans, has been spared the Ebola pandemics.

The new measures will likely take effect soon, with the agency predicting that “within the next few days” it will be time for the new rules to take effect.

“As of today, there are no new U.D.C.’s or CDCs in the country,” Frieden added.
