• Note: As Transmissions usually increase the Pathogen's Infectivity instead of other Stats, none of the Transmissions listed here increase Severity or Lethality, with the exception of Bird 2, Bat 2, Rodent 2, and Air 3.

Transmission	Description	Base Cost	Infectivity	Other increases
Data Source: Necroa Virus Trait Stats (Game File: necroa.txt)
Insect	Insects susceptible to infection. Carriers increase infectivity, especially in hot climates and chance of mutation	8	5	+0.1 in Hot Climates -0.03 Research Work +0.5 Mutation
Zoonotic Shift	Genetic shift in virus increases infectivity, mutation chance and makes cross species infection possible. Increases future research speed	3	3	-0.02 Research Work +0.2 Mutation
Bird 1	Host range broadens to include birds. Increases infectivity, land transmission and mutation chance	13	4	+9 Land Transmission -0.03 Research Work +1 Mutation
Bat 1	Host range broadens to include bats which are hard to detect. Increases infectivity and mutation chance	9	7	-0.02 Research Work +0.5 Mutation
Rodent 1	Host range broadens to include rats. Increases infectivity, especially in urban regions and mutation chance	7	4	+0.8 in Urban Countries -0.04 Research Work +0.5 Mutation
Bird 2	Partial genetic activation triggers random bird attacks on humans. Significantly increases infectivity and land transmission	18	6	+3 Severity +70 Land Transmission -0.05 Research Work +0.2 Mutation
Bat 2	Partial genetic activation causes bats to mob and attack humans at night. Significantly increases infectivity and attacks can be lethal	15	8	+5 Severity +1 Lethality -0.02 Research Work +0.2 Mutation
Rodent 2	Partial genetic activation causes rat packs to attack humans. Significantly increases infectivity, especially in urban regions	15	7	+4 Severity +1.2 in Urban Countries -0.05 Research Work +0.2 Mutation
Saliva 1	Virus replicates faster in salivary glands - increasing chance of infection through contact with saliva	6	3	+0.1 Mutation
Saliva 2	Virus replicates directly in nasal cavity - significantly increasing chance of infection through contact with mucus	5	3	+0.1 Mutation
Gastrointestinal Expansion	Virus can replicate in stomach and intestine, increasing infectiousness through faeces and vomit	8	6
Urogenital Expansion	Virus can replicate in kidneys and urinary tract, increasing infectiousness through urine and other bodily fluids	7	7
Water 1	Virus can survive outside the body in fresh, warm water. Increase infectivity, especially in humid environments and ship transmission	5	2	+9 Boat Transmission +0.8 in Humid Climates
Water 2	Virus able to survive in chemically treated water. Increase infectivity, especially in humid environments and ship transmission	11	7	+90 Boat Transmission +1.2 in Humid Climates
Blood 1	Virus enters the circulatory system, blood is now a transmission vector. Poor countries particularly vulnerable	9	3	+0.8 in Poor Countries +0.1 Mutation
Blood 2	Virus can replicate directly in the blood stream, significantly increasing infectivity. Poor countries particularly vulnerable	11	4	+1.2 in Poor Countries +0.1 Mutation
Air 1	Virus bypasses alveolar macrophages in lungs to enter bloodstream. Increase infectivity, especially in arid environments and plane transmission	6	3	+9 Airplane Transmission +0.8 in Arid Countries
Air 2	Virus can travel on dust particles. Increases infectivity, especially in arid environments and plane transmission	10	6	+90 Airplane Transmission +1.2 in Arid Countries
Air 3	Virus replicates rapidly in aerosoled brain matter. Significantly increases risk of infection if interacting with zombie brains	8	3	+8 Severity +0.05 Cure Work
Segmented Genome	Virus splits its genome into smaller molecules - increasing the likelihood of a viable mutation during transmission	19	0	+2.5 Mutation
