A Passenger, Quarantine, and Home Monitoring: Short Lessons on the Hantavirus Response

A hantavirus outbreak on the MV Hondius cruise ship prompted a multinational response in May 2026. Several Americans were repatriated and taken to specialized care units. Many other passengers have been allowed to return home for monitoring by local health officials.

One passenger, Angela Perryman, said she wanted to be monitored in South Florida but was held at the National Quarantine Unit in Nebraska. She and at least one other person were given a legal order on May 18 that required them to stay at the facility until the end of the month. The CDC has publicly acknowledged two mandatory quarantine orders.

The federal quarantine orders were issued under U.S. public health law, and the orders were signed by the CDC’s acting director. While public health experts say separation can protect the public, some legal scholars have questioned whether less restrictive monitoring would be lawful in this case. CDC guidance has emphasized careful observation because there is no vaccine and person-to-person spread can sometimes occur.
