The total number of confirmed cases associated with the outbreak is increasing, health officials said. To date, three people who were aboard the ship are known to have died of the virus.
No U.S. residents have experienced any signs of illness as of Friday morning, according to health officials.
Health officials in Texas, New Jersey and Georgia are monitoring two people while officials in California, Virginia and Arizona say they each are monitoring one person.
More than 100 passengers remain on the ship, and the World Health Organization is monitoring their health. Officials said that the "overall public health risk remains low" but that there may be some person-to-person spread.
A Centers for Disease Control and Prevention official confirmed to ABC News on Friday that the agency will be dispatching personnel to the Canary Islands and bring back Americans to the National Quarantine Unit in Nebraska.
According to the New Jersey Department of Health, an infected person had departed from the cruise ship MV Hondius, and the potential exposure to the New Jersey residents happened during air travel abroad.
The state health department went on to say that neither individual is currently reported to have symptoms suggestive of hantavirus. The New Jersey residents were not passengers on the cruise ship.
Officials said they will not release any information about where in New Jersey those residents live, or any other identifying details, to protect their privacy.

The state health department said it is working with local health officials to monitor returning travelers as a precaution.
"At this time, the risk to the general public in New Jersey remains very low. No current hantavirus cases have been identified in the state, and there is no history of a confirmed hantavirus case reported in New Jersey," the state department of health said.

The state health department added the following:
Hantaviruses circulating in the United States are carried by rodents and are not known to spread between people. The strain associated with the MV Hondius outbreak - Andes virus - is found in South America and is the only known hantavirus capable of person-to-person transmission, though such transmission is rare and generally requires close, prolonged contact with an infected individual or their bodily fluids.
The incubation period ranges from four to 42 days and asymptomatic persons are not considered infectious.
Health agencies in several other U.S. states are conducting similar monitoring of returning passengers. NJDOH will continue to coordinate with local and federal public health partners and will provide updates as the situation develops.
This is an evolving public health situation. The information provided reflects current knowledge and is subject to change as additional facts are confirmed by local, federal, and international partners.
