It's uncertain what this status effect is called yet, but it's a brand new effect caused by Stygian Zinogre's Dracophage Bugs.

This effect had one core and rather worrying point, the Dracophage Bugs themselves latch onto you and start eroding your items and weapon, causing you to completely lose items and lowering your weapons sharpness overtime the longer they are swarming you.

On top of this, your screen will also be covered by a red mist like effect (As shown in the image) that will flicker over, making is slightly harder to see.

Looking at the image, you can actually see a swarm of Dracophage Bugs around the hunter, as well as two on your sharpness gauge icon. The text on screen, "元気ドリンコが蝕まれた" translates to "Energy Drink has been eroded", destroying the item.
