90-Second Read: Hantavirus live updates: 15 in quarantine in Nebraska, 1 in biocontainment unit

The total number of confirmed and probable cases of Hantavirus onboard the MV Hondius cruise ship has risen to 11. Fifteen of those passengers were being monitored in a quarantine unit and another, who had tested positive, was in a biocontainment unit, officials said. Speaking to CNN, Kornfeld talked about being in the biocontainment unit at the University of Nebraska Medical Center after he too tested positive for the Hantavirus. Two cruise ship passengers complimented the quarantine staff and doctors.

David Fitter, the incident manager for CDC's Hantavirus response, told reporters in a telephone news conference that the agency has over 100 staff working full time on the outbreak. Steve Kornfeld, a physician who was onboard the MV Hondius and stepped in when the ship's physician contracted the virus, opened up about his own quarantine in Nebraska. The Minnesota Department of Health said it's monitoring the condition of a person who "may have briefly been exposed overseas" to another person who tested positive for Hantavirus after being on board the MV Hondius. Passengers began disembarking on Sunday in the Canary Islands, where many boarded charter flights to their home countries.

Sixteen American passengers arrived on Monday at the University of Nebraska Medical Center. Hantaviruses may also spread from person to person, but that also is rare and only suspected for one subtype from South America, according to the WHO. Jake Rosmarin, one of the American cruise patients currently quarantining in Nebraska, provided an update on his Instagram page Wednesday. After experiencing "night sweats, chills and mild respiratory symptoms, as well as more than two weeks of severe fatigue," he told CNN that he is experiencing no symptoms and is in good spirits.

On his third day of quarantine at the National Quarantine Unit, Rosmarin showed off his thermometer used to take his temperature, his breakfast and his daily routine. They have been very cooperative, and we are monitoring them daily for symptoms. Kornfeld added that the time is passing quickly and he's spending a lot of time on WhatsApp.
