CARRIER

[noun] [C]A carrier is a person who has bacteria or a faulty gene which causes a particular disease and can give that disease to other people without suffering from the disease him- or herself.Dr Sewards estimates that as many as 1 in every 7 of the community is a carrier of the defective gene.At present only about 10% of the US's 1.5 million HIV carriers know that they carry the disease.
