As many of us from Durham's class know, Hantavirus is a robovirus that was was famous in the US for its epidemic in the four corners region. El nino caused increased rainfall -> which led to increased food for mice -> increased mice population -> more mice competition -> more mice biting (and spreading the disease) -> mice coming into homes, pooping and peeing everywhere -> humans infected with the sin nombre virus.
Apparently there was an outbreak in Sweden as well, and the virus caused the characteristic hemorrhagic fever with renal syndrome.
In connection with last year's epidemic, a research team at Umeå University in Sweden has managed for the first time to show that hantavirus exists in human saliva. This raises the question of whether this contagion can spread among humans.

Will Hantavirus spread from human to human then?
... does this mean Hantavirus could be a new, but more dangerous, virus like mono?
