SURVIVOR HEALTH · DAYZ
Common cold
The common cold is an early illness state driven by the INFLUENZA agent.
Effects in DayZ
The modifier starts at 100 influenza agents and causes sneezing. It deactivates at an agent count of zero.
What helps
Antibiotics attack the influenza agent, which has zero antibiotic resistance. Immunity also affects the agent system.
Important distinctions
Common cold, influenza and pneumonia share an agent but have different modifiers. Suppressing a sneeze does not necessarily clear the agent.
