The US Centers for Disease Control and Prevention has classified the hantavirus outbreak as a “Level 3” threat and activated its Emergency Operations Centers, according to a report.

The risk to the public remains low, but epidemiologists, scientists, and physicians may be reassigned to monitor and assist with the disease response, several sources told ABC News Thursday.

By activating the Emergency Operations Centers, it means that there is a team ready to support whatever response may be necessary.

Many small natural disasters in the US tend to involve Level 3 responses under the CDC’s Emergency Management Program.

President Trump said he has been briefed on the hantavirus outbreak on the Dutch-flagged ship MV Hondius, which is en-route to the Canary Islands and expected to arrive Saturday.

“It should be fine. We hope,” he told reporters while speaking about the outbreak. “It’s very much – we hope – under control.”

He confirmed that a “full report” will be issued Friday – but stopped short of providing the exact details on what it might feature.

Trump also tried to reassure Americans when asked if they should be worried about the outbreak.

“I hope not, I mean, I hope not,” he said. “We’ll do the best we can.”

State agencies are monitoring American passengers who were on board the ship and have since returned home.

The passengers did not know that they had been exposed to the virus when they left the boat at Saint Helena on April 24.

Texas said the two residents have agreed to monitor their temperature daily for possible infection — but they are not currently showing infection.

The two Georgia residents are in good health, showing no signs of infection and following recommendations from the Centers for Disease Control and Prevention, the Georgia Department of Public Health said.

The Arizona passenger was not experiencing symptoms either, according to the state’s health services department.

The Virginia resident was “currently in good health” and being monitored, the Virginia Department of Health said.

Six Americans were among the 30 passengers who disembarked during the ship’s stop in Saint Helena, the vessel’s operator, Oceanwide Expeditions, revealed Thursday.

Hantavirus reached Europe earlier this week, with a man, who had left the boat, turning himself into a Zurich, Switzerland, hospital after exhibiting symptoms.

The European Centre for Disease Prevention and Control has also activated its response regarding the Andes hantavirus outbreak, which carries a mortality rate of 40%.

Officials confirmed Wednesday that an EU Health Force Task official had been deployed to the cruise ship.

Similarly to its American counterparts, the ECDC has said the risk to the population is very low.

Three suspected hantavirus patients were evacuated from the MV Hondius while it was in West African waters, off the coast of Cape Verde, and are receiving treatment.

A British man, 69, is being treated in a South African hospital but the UK’s Health Security Agency announced Friday an additional suspected case of the virus on the South Atlantic island of Tristan da Cunha.

The MV Hondius stopped briefly on the archipelago in mid-April.
