Pneumonia

Pneumonia is a severe INFLUENZA-agent condition with health and stamina penalties.

Effects in DayZ

It activates at 1,150 influenza agents and deactivates at 1,100 or below.

It drains health, can cause gasping, increases stamina depletion and reduces stamina recovery.

Treating the underlying influenza agent with antibiotics can reduce the load that activates this modifier.

Pneumonia shares the influenza agent. Its health drain is additional to its stamina effects.
