Hantavirus cases linked to the cruise ship M/V Hondius are growing as health officials say the virus jumped from person to person. As @Ramy Inocencio reports, a new case involving a French man who was not on that 35-day luxury cruise is raising concerns that hundreds in the air and on the ground may have also been exposed. Contact tracing has begun. #hantavirus

Intervirus infections have risen again from seven people who were on board the M.V. Hondius to at least two new people for a total of at least nine. And one of those two new cases was not a passenger on that ship. And this is concerning because it means that antivirus has spread from person to person. Now, this case involves a French national, according to France's Ministry of Health, and French media who said that this is a man. French media also believe he traveled on this plane, which our CBS News confirms Joanne's stalker tracked. This is air link flight 4Z132 from the island of St Helena to Johannesburg, South Africa, and this was on April 25th. It's believed it was the same plane as one of the first passengers who got sick on the ship. That was a 69-year-old Dutch woman who collapsed just hours after she landed in Johannesburg. Her 70-year-old husband had already died on the ship, and he was the first victim in this antivirus outbreak. Now, making this more concerning, there were about 85 passengers and crew on that same flight. And then there is the second new confirmed case, which the World Health Organization has confirmed. This case involves a Swiss national and also a man, and he is linked to the ship and was another passenger. Now, we understand sometime in late April, he left the ship with his wife and flew home to Zurich. It's not clear when exactly at this point, but it could have been from St Helena or after from Ascension Island. And this is according to the ship's itinerary. Now, in Zurich, he felt sick. He was tested for antivirus and was confirmed to have the Andy's strain. This is the one that can jump from human to human. He's now hospitalized and in isolation in Zurich. His wife isn't showing any symptoms, and she is self-isolating. But what are a flight or flights this man and his wife took to get home will be in focus for more contact tracing, which could involve hundreds more people in planes and on the ground.
