Immune System

A character's  is a core Survival Character Stat in DayZ Standalone and can be boosted by consuming Multivitamin Pills. This stat provides raw resistance against contracting illnesses such as Infection and Cholera. You will get an illness if you eat any meat that is raw, eat or drink with bloody hands, or drink from a dirty water source.

When your immune system is above 95% you are immune to all diseases except for Brain Prion Disease. Meaning you could eat raw food and drink questionable liquids and not get sick. Note, that there are no additional benefits to having your immune system about 95%. To tell if your immune system is above 95%, your food and water stats along with health and blood must be full. When your immune system is above 65% you are immune to Influenza and Common Cold only. Any lower than 65% and you are immune to nothing. Multivitamin Pills will boost your immune system to 100% for 5 minutes, which can be beneficial if you are in a pinch and need food desperately. Try not to drink from Canteens, Plastic Bottles, or anything that can hold water until it is purified or emptied, as it can lead to an illness.
