Associated Press is reporting that a hepatitis A outbreak hit the Brazilian soccer team Internacional, sidelining five players who are now banned from any contact with teammates.

The team said the liver disease probably spread from player to player in the locker room, most likely through shared water bottles.

Except hepatitis A is not spread by saliva; it’s spread by poop. So there was either poop on the water bottles — possibly from someone’s hand — or poop in the water.

Or the water bottle theory is wrong.

Internacional is a former club world champion.
