Now that extra than 100 passengers aboard a hantavirus-stricken luxurious cruise ship have been evacuated, with 18 People in biocontainment items in Nebraska and Georgia, well being officers all over the world are working to watch greater than two dozen people who left the cruise and anybody with whom they could have are available in shut contact.
To this point, the entire 11 reported hantavirus circumstances are amongst passengers or crew on the ship, the World Well being Group’s director-general Tedros Adhanom Ghebreyesus mentioned at a press conference in Madrid on Tuesday. That features three deaths ensuing from the virus.
Usually, hantaviruses are unfold when contaminated rodent droppings and urine are stirred up within the air and breathed in. The pressure recognized on board the cruise ship, the MV Hondius, is called the Andes virus, and is the one sort identified to transmit from individual to individual. Whereas the virus could cause severe illness and carries a excessive fertility fee, well being officers say the hantavirus outbreak is unlikely to develop into a worldwide disaster just like the Covid-19 pandemic.
“In the intervening time, there isn’t a signal that we’re seeing the beginning of a bigger outbreak,” Ghebreyesus mentioned, “however after all the scenario may change and, given the lengthy incubation interval of the virus, it’s attainable we would see extra circumstances within the coming weeks.”
WIRED spoke with Nicole Iovine, chief epidemiologist and an infectious illness skilled on the College of Florida Well being, about how the Andes virus spreads and whether or not it is more likely to spark one other pandemic.

WIRED: One of many issues that’s in all probability high of thoughts for most individuals is how comparable is the Andes virus to SARS-Cov-2, and the way infectious is it?
Nicole Iovine: It’s not comparable in any respect to SARS-Cov-2. This outbreak on the cruise ship shouldn’t be going to translate right into a worldwide pandemic like Covid for plenty of causes. One of many causes is that it’s simply not as infectious as Covid was. Covid contaminated our higher airways and likewise deep in our lungs. However the truth that it contaminated our higher airways meant that once we talked or sneezed or coughed, it was simply put out into the air and so it was straightforward to transmit. With the Andes virus, this virus really infects very deep within the lungs. It does not usually infect the higher airways, so it is lots tougher for it to transmit from one particular person to a different.
How would you realize should you had the Andes virus? It looks like the signs are fairly nonspecific at first however progress rapidly to severe illness.
Individuals can begin to get signs wherever from about 5 days or so after publicity to so long as six weeks, which is once more very totally different from Covid and another excuse why hantavirus is of some concern however shouldn’t be more likely to trigger a pandemic. It begins out with very generalized signs. You may develop a fever, headache, fatigue, muscle aches and pains. These types of signs are what you’ll get should you had the flu or many different types of infections.
Is the Andes virus airborne?
Not precisely, as a result of the way in which that it transmits into your lungs is if in case you have actually shut contact with somebody for an considerable period of time. It isn’t one thing like measles, the place should you’re in a room and you’ve got measles, any person may come into that room two hours later and nonetheless contract measles. That is airborne, however hantavirus shouldn’t be like that.
