A hereditary carrier (genetic carrier or just carrier), is a person or other organism that has inherited a recessive allele for a genetic trait or mutation but usually does not display that trait or show symptoms of the disease. Carriers are, however, able to pass the allele onto their offspring, who may then express the genetic trait.
For example, under the law of the United States, a U.S. flag air carrier is any airline that holds a certificate under Section 401 of the Federal Aviation Act of 1958 (i.e., any U.S.-based airline operating internationally), [5] and any ship registered in the United States is known as a U.S. flag vessel.
An asymptomatic carrier is a person or other organism that has become infected with a pathogen, but shows no signs or symptoms. [ 1 ] Although unaffected by the pathogen, carriers can transmit it to others or develop symptoms in later stages of the disease.
Disease carrier could refer to: Asymptomatic carrier , a person or organism infected with an infectious disease agent, but displays no symptoms Genetic carrier , a person or organism that has inherited a genetic trait or mutation, but displays no symptoms
An obligate carrier is an individual who may be clinically unaffected but who must carry a gene mutation based on analysis of the family history; usually applies to disorders inherited in an autosomal recessive and X-linked recessive manner.

The disease is X-linked and the father cannot pass haemophilia through the Y-chromosome. Males with the disorder are then no more likely to pass on the gene to their children than carrier females, though all daughters they sire will be carriers and all sons they father will not have haemophilia (unless the mother is a carrier) [35]
Often simply called an antiviral. A class of antimicrobial medication used specifically for treating diseases caused by viral infections rather than ones caused by bacteria or other infectious agents. Unlike most antibiotics, antivirals typically do not destroy their target viruses but instead inhibit their development. They are distinct from virucides. assembly The construction of the virus ...
