Nebraska Medical Center Validates Andes Virus PCR Test for 16 Cruise Passengers
10 articles · Updated · WIRED · May 13
A University of Nebraska Medical Center lab built and validated an Andes virus PCR test within days, giving it capacity to run a few hundred patient samples before testing 16 exposed cruise passengers.
About 300 tests' worth of materials arrived from a University of New Mexico lab, and Nebraska used roughly one-third to validate the assay by detecting Andes genetic material at varying concentrations in healthy blood samples.
The push exposed a US testing gap: CDC can run an Andes serology test only after antibodies appear, while its own PCR assay remains a research test not yet cleared for patient management.
Andes virus differs genetically from US hantavirus strains, carries an estimated 35% fatality rate, and can cause fluid buildup in the lungs; early detection can speed supportive care that improves survival.
State hantavirus testing capacity remains limited, though several public health labs are now trying to add PCR capability as officials apply lessons from the flawed early Covid test rollout.

2026 MV Hondius Andes Hantavirus Outbreak: U.S. Quarantine, Nebraska Medical Center’s PCR Breakthrough, and International Public Health Response
Overview
After the MV Hondius cruise ship incident, where three passengers died and several others became ill or tested positive for hantavirus following their departure from Argentina, the United States quickly focused on managing the health risks. Passengers returning from the ship were placed under structured quarantine and daily monitoring, following World Health Organization recommendations. This careful approach aimed to detect any emerging symptoms early and prevent further spread. The U.S. response highlights the importance of coordinated quarantine protocols and international guidance in handling infectious disease outbreaks linked to global travel.
