I found an interesting article, not good, just interesting. Strange stuff! In the water? I hope they run out of Hepatitis Types before they run out of alphabet...

Five French patients infected with hepatitis E strain found in rabbits

In a rare finding, researchers in France discovered five cases of human infection with a hepatitis E virus strain found in rabbits. 

The researchers said they could not identify how the patients — who were not all from the same region — were infected with the HEV3-ra strain but suspect it might have been via waterborne transmission because the strain was found in environmental samples.
