The two people were not passengers on the cruise ship and officials say the potential exposure happened during air travel abroad.
Three people have died from the outbreak tied to the ship.
The New Jersey Department of Health was notified by the U.S. Centers for Disease Control and Prevention about the potential exposure and they say they are monitoring the residents as a precaution.
Neither individual is currently reported to have symptoms suggestive of hantavirus.
Health officials say the risk to the general public in New Jersey remains very low.
No current cases have been identified in the state and there is no history of a confirmed hantavirus case reported in New Jersey.
Health officials in several countries are trying to identify and follow people who may have been exposed to hantavirus on the cruise ship.
In addition to contact tracing, they are trying to learn more about the virus as fast as they can. Questions include whether it has mutated and how exactly it spreads. Hantaviruses usually spread when people inhale contaminated residue of rodent droppings.
While human cases are rare, small outbreaks have been documented around the world. And the Andes virus implicated in the outbreak unfolding on a cruise ship now in the Atlantic Ocean may be able to spread between people in rare cases.
