A South Bay resident from Santa Clara County was on the MV Hondius cruise ship but disembarked before the outbreak. Two other Californians were also on the ship and disembarked over the weekend in the Canary Islands. They are now in quarantine at a federal facility in Nebraska.

The fourth Californian, a Sacramento County resident, has returned home. That person was not on the ship but was exposed to someone who was ill on a plane in South Africa, according to health officials.
All four individuals are being closely monitored.
State health officials addressed questions about the two people who have returned home to California and whether they are in quarantine. Dr. Erica Pan said, "They're doing modified activities in alignment with our Centers for Disease Control guidance as well. So they are limiting acitivities outside the home. They're doing daily temperatures and are in contact with their local health departments."
Health officials continue to say that the hantavirus risk to the general public remains extremely low.
