HPS is a severe and potentially deadly disease that affects the lungs. Symptoms of HPS usually start to show 1 to 8 weeks after contact with an infected rodent.

Early symptoms can include:

fatigue fever muscle aches, especially in the large muscle groups like the thighs, hips, back, and sometimes shoulders About half of all HPS patients also experience:

headaches dizziness chills abdominal problems, like nausea, vomiting, diarrhea, and abdominal pain Four to 10 days after the initial phase of illness, the late symptoms of HPS appear. These symptoms include coughing and shortness of breath. Patients might experience tightness in the chest, as the lungs fill with fluid.

HPS can be deadly. Thirty-eight percent of people who develop respiratory symptoms may die from the disease.

Hantavirus can be spread once mild symptoms appear, which unfortunately are so mild that most people wouldn’t even think about it being hantavirus. And it can take up to 8 weeks for symptoms to start to appear.

Edit: In addition, the fact that a flight attendant managed to catch it does speak towards it being more contagious than previously thought.

Yeah obviously a disease is caught from somewhere and they thing it has been transmitted human to human but seems to require close contact like family in the same cabin. This is all from the articles. In animals it required fluid contact and given what they see I think the assumption that would be needed I don’t think is a crazy assumption. This means any risk of contagion just requires simple isolation and you don’t have to have 10 foot rules and n95’s and such. Maybe a mask or shield to keep from inhaling cough spittle and gloves along with good hygene. Its doubtful such a thing could get out of control unless it was very mild and lack symptoms for awhile which does not appear to be the case.
