Carriers are individuals or entities that transport goods or people from one location to another. They can be companies, such as shipping firms or airlines, that specialize in moving products across distances. Carriers play a crucial role in logistics, ensuring that items reach their destinations safely and efficiently. In the context of healthcare, carriers refer to individuals who possess a gene for a specific disease but do not exhibit symptoms themselves. For example, a genetic disorder may be passed on to offspring if one parent is a carrier. Understanding carriers is important for genetic counseling and disease prevention.
