American passengers from the cruise ship at the center of the hantavirus outbreak, including at least one who inconclusively tested positive, arrived in Omaha, Nebraska, early Monday for evaluation at a highly specialized quarantine unit, CNN reported. Seventeen U.S. citizens and one British national who lives in the U.S. entered the only federally funded quarantine unit in the U.S., designed specifically to safely house and monitor people who may have been exposed to high-consequence infectious diseases. 

One of the Americans has tested “mildly” positive for the virus, and another has mild symptoms, the Department of Health and Human Services said late Sunday. Both traveled in biocontainment units on the plane. The passenger who tested positive does not have symptoms but was taken directly to the biocontainment unit at the University of Nebraska Medical Center in Omaha. The other passengers went to the center’s National Quarantine Unit for assessment and monitoring.

The Centers for Disease Control and Prevention (CDC) was not treating this as a quarantine for the cruise ship passengers, but rather as a brief visit to monitor their health. Once at the facility, the passengers will be checked for symptoms of early hantavirus infection, including fever, muscle aches, and diarrhea.

Later on Monday, two American MV Hondius Passengers were transferred to Emory University Hospital’s Serious Communicable Diseases Unit in Atlanta, CNN reported. One person is experiencing symptoms and the other person is a close contact.

The hantavirus outbreak was first reported to the World Health Organization (WHO) on May 2. The virus, typically associated with rodents, may have been transmitted from person to person aboard the MV Hondius cruise ship, the WHO said. Since April 11, three people from the ship have died. As of May 8, there were eight total cases connected to the MV Hondius cruise ship—six lab-confirmed plus two probable cases.

On Friday, the CDC said the risk to the public remains low, although ISSA’s Dr. Gavin Macgregor-Skinner said the virus represents a significant health risk for those cleaning areas where the virus is present. Additionally, seven American passengers who previously disembarked the ship are being monitored in five states: Arizona, California, Georgia, Texas, and Virginia, officials said. New Jersey officials also are monitoring two others who were not on the ship but may have been exposed on a flight.

ISSA, the Association for Cleaning & Facility Solutions, released the speakers for the 2026 ISSA Altus Summit, a leadership experience designed exclusively for building service contractor (BSC) executives committed to strengthening their businesses and advancing the cleaning industry.

Taking place June 8-10 at ISSA headquarters in Rosemont, Illinois, the Altus Summit is the flagship in-person gathering for ISSA’s community of BSC leaders. ISSA curated the Altus Summit to provide a focused, high-trust environment to refocus, realign, and return with a stronger path forward. The event features ISSA’s six Altus Principals, BSC leaders who represent specific disciplines that drive successful cleaning companies:

• Chase Carlson, Pioneer president and CEO, focusing on operations.
• Mike Fitts, 4M Building Solutions chief commercial officer, focusing on strategy.
• Jill Frey, Cummins Facility Services president and CEO, focusing on technology.
• Channing Johnson, KB Building Services president, focusing on human resources.
• Steve Mastin, 4M Building Solutions chief financial officer, focusing on finance.
• Ricky Regalado, Route/Rozalado Services CEO and founder, focusing on sales and marketing.

“The Altus Summit reflects what the BSC community has been asking for: a forum where leaders learn from leaders, where strategy meets execution, and where conversations are honest, relevant, and operator-driven,” said Karina Neff, ISSA Chief Engagement Officer for BSCs. “Our Altus Principals don’t just speak to the issues facing today’s BSCs—they live them. That’s what makes this experience unlike anything else in the industry. It’s built by BSCs, for BSCs.”

In addition to the Altus Principals, the Altus Summit agenda features industry thought leaders such as Laurie Sewell, president of Servicon and president of the ISSA Board of Directors; Mark Herbick, founder and CEO of Pursant; Doug Flaig, CEO of Stratus Clean; Otis Scott, vice president of human resources at Prestige Maintenance USA; and Jill Davie, senior vice president and general manager at WorkWave.

“The Summit is not a conference attendees sit through, but a leadership community they step into,” Neff said. “Every session, peer exchange, and conversation is designed to deliver real insights, sharpen strategy, and produce decisions BSC executives can act on the moment they return home. We are thrilled to host such a powerful program—and equally excited to welcome a remarkable lineup of speakers and thought leaders whose expertise will add tremendous value for every executive in the room.”
