This value set expansion contains 3 concepts.

System	Version	Code	Display	Definition
`http://terminology.hl7.org/CodeSystem/v3-RoleClass`	3.1.0	EXPAGTCAR	exposure agent carrier	An exposure agent carrier is an entity that is capable of conveying an exposure agent from one entity to another. The scoper of the role must be the exposure agent (e.g., pathogen).
`http://terminology.hl7.org/CodeSystem/v3-RoleClass`	3.1.0	EXPVECTOR	exposure vector	Description: A vector is a living subject that carries an exposure agent. The vector does not cause the disease itself, but exposes targets to the exposure agent. A mosquito carrying malaria is an example of a vector. The scoper of the role must be the exposure agent (e.g., pathogen).
`http://terminology.hl7.org/CodeSystem/v3-RoleClass`	3.1.0	FOMITE	fomite	Description: A fomite is a non-living entity that is capable of conveying exposure agent from one entity to another. A doorknob contaminated with a Norovirus is an example of a fomite. Anyone touching the doorknob would be exposed to the virus. The scoper of the role must be the exposure agent (e.g., pathogen).
