Rode a thyla in swamp. I got swamp fever and couldn't ride my tame

To get a leech off of you, you need to create a fire and jump on the fire for a few seconds until the leech dies

On the island there’s many outbreaks of “swamp fever”. You get Swamp fever by getting a infected leech stuck on you and TRANSFERRING NO longer Gets RID of SWAMP FEVER.

This is for anyone who doesn't know how to get a leech off on ark, all you got to do is light a campfire and stand on it, then it comes off. Really simple.

No latch onto Beelzebufos

FOR MOBILE PLAYERS ONLY:

These are in the swamp, they’re just super rare and you rarely will find them. They must be removed via campfire or cooking pot, same thing applies to dinos that aren’t native to the swamp.

FOR MOBILE PLAYERS ONLY:

I read on the ark wiki that they dont latch onto tames native to the swamp

WATCH OUT THEY GO ON LAND AND WIGGLE

Fire doesn’t work to remove leeches anymore. Go to a tamed animal, open command wheel and click “hold to remove leech.”

The yutyrannus, not the rex, is your best friend for leech hunting. The leech is vulnerable to the fear roar, and the debuff reveals their location. This makes hunting them a simple errand. You'll collect so much leech blood you could start a swamp fever clinic.
