Skin Lesions is a tier 3 symptom. It greatly increases infectivity (the most infective symptom in the basic plagues) by causing large open wounds (large boils on the skin) to form. It is the only non-lethal symptom that overthrows Necrosis in infection rates (11% to 10%), and the only non-lethal tier 3 symptom in the normal game. Skin Lesions are highly recommended when infecting people in a quick and effective manner.

Although not deadly, it is noticed in every plague type on all difficulties, regardless of what the player does (Other than Symbiosis 3, which is exclusive to the Parasite disease type).

It can be evolved with the tier 2 symptom Haemophilia to acquire the Profuse Bleeding symptom combo, which is slightly lethal and increases infection rates. This combo also unlocks the Red Rain achievement.
