Onboard the MV Hondius cruise ship, an alarming situation has unfolded, with oncologist Dr. Stephen Kornfeld identifying himself as the American passenger who has tested ‘mildly PCR positive’ for hantavirus. Following these developments, Kornfeld has been placed in quarantine at a biocontainment unit located at the University of Nebraska Medical Center.

In an appearance on CNN, Dr. Kornfeld shared insights into his condition and the protective measures undertaken in the biocontainment facility. He expressed optimism about his health, stating, “I feel great. I feel wonderful, 100%,” despite testing positive for the virus. Dr. Kornfeld was on the cruise for leisure purposes, but took on the role of assisting fellow passengers who fell ill after the ship’s doctor also became unwell.
The U.S. Department of Health and Human Services (HHS) reported Kornfeld’s positive test result on May 10, which prompted a thorough investigation. Establishing the context, the doctor noted that he had taken multiple tests for hantavirus while aboard the cruise in early May, which were submitted to two different laboratories in the Netherlands. The results revealed one negative test and one that was faintly positive.
Describing the bureaucratic steps that followed, Kornfeld said, “One was negative and one was faintly positive. I was told the test was intermediate, but since it wasn’t a negative, it’s being looked at as a potential positive.” These results were communicated to the Centers for Disease Control and Prevention (CDC), leading to his current status in quarantine. He is expecting to receive further results from the CDC in the days to come.
While isolating in the biocontainment unit, Kornfeld elaborated on the measures in place, noting the facility’s stringent security protocols. “If I were to get sick and spill the virus, there’s no way this virus is getting out of this building,” he explained. The environment, while resembling typical hospital settings, is heavily fortified with multiple layers of safety checks.
Reflecting on his experience during the cruise, Dr. Kornfeld recounted how he initially presented flu-like symptoms in April. During his time on the MV Hondius, he experienced night sweats, significant fatigue, and mild respiratory issues. Although he felt unwell for three days, he managed to participate in various activities on the ship afterward. “It felt like just some virus,” he expressed, indicating that he and several fellow travellers shared similar symptoms at the time.
Kornfeld speculated on the potential source of his exposure, suggesting that he may have had contact with the virus prior to the ship’s outbreak. At that time, he interacted with a passenger who later succumbed to the illness. “There’s no way to really know” if his initial symptoms were indeed caused by hantavirus, he mentioned.
At present, he is the sole patient in his biocontainment unit, describing the experience as “a little weird” yet comfortable. He remains in contact with doctors and nurses, who wear full protective gear while attending to him. “I just see a pair of eyes,” Kornfeld stated, humourously noting that he struggles to recognise even familiar faces behind the protective masks.
In light of the situation, it has been recommended that all passengers connected with the outbreak remain in quarantine for a period of 42 days. Currently, the group consists of 17 American individuals who have all expressed their commitment to adhere voluntarily to these guidelines. Additionally, a British dual-national is also under medical observation in the U.S.
Three fatalities have been reported in connection to this outbreak, with two individuals confirmed to have contracted hantavirus. Among the deceased is an elderly Dutch man, with his wife also affected by illness, alongside a German woman. Complicating the situation, a French woman remains in critical condition, reliant on an artificial lung as treatment. Meanwhile, a spokesperson for the South African health ministry confirmed that a British man receiving care is showing signs of gradual improvement, though he remains unwell.
As investigations continue and health authorities monitor affected individuals, the World Health Organization (WHO) cautions that symptoms of hantavirus can take up to eight weeks to manifest, emphasising the importance of vigilance and ongoing observation for those who may have been in contact with the virus.
