yup,

some joker druid and his hunter friend brought the disease after fighting in ZG.

after the outbreak... tons of bodies littered the Bank, Mailbox, Inns, Griffon master, AH. So happen a bunch of horde were raiding also... and they got the disease too...

Characteristics of the disease:-

Last only 3 or 4 secs

Does about 250 - 400 dmg i think ever 2 secs.
Transferable to other players

1 hunter and 1 pet plus 1 healer = GG IF

btw.. if u think it actually reduced the lag in IF, think again... it made it worse
