Mole rat disease

Mole rat disease is a potentially permanent effect the player character obtains if bitten by an infected mole rat in Vault 81.

Characteristics
The effect is -10 Max HP, or permanently lowers the Sole Survivor's level by 1. During the quest Hole in the Wall, one will obtain the only dose of the cure available. If the player character has contracted the disease, they must choose between curing themselves or Austin Engill, an infected child.

Bugs

 * It is possible to contract the virus without being bitten by a mole rat. This can be caused by a companion or the sentinel AI power armor killing a molerat.
 * If the dormant Protectron is activated and bitten, the Sole Survivor will contract the disease.
